Baseball has seen its share of players who have been hyped before they ever played a game in the Major Leagues. Rarer, though, are the players who have managed to live up to the immense hype that followed them to MLB.
Roman Anthony and Kevin McGonigle are among the latest youngsters facing that test.
Anthony debuted last June, joining the Red Sox amid plenty of fanfare as MLB Pipeline's No. 1 overall prospect. Despite playing just 71 games, he managed to finish third in the AL Rookie of the Year Award race, raising expectations for what he might be capable of in 2026.
McGonigle, meanwhile, is MLB Pipeline's No. 2 overall prospect and made his highly anticipated debut Thursday as Detroit kicked off the 2026 season. He didn't disappoint, becoming the second player in Tigers history with a four-hit performance in his first game.
With Anthony and McGonigle looking to cement themselves as bona fide superstars in the years ahead, let's take a look at some of the most anticipated debuts that preceded notable careers, including both active stars and retired legends.
ACTIVE STARS
Paul Skenes, Pirates -- May 11, 2024
After capturing national attention pitching for LSU, Skenes was selected first overall in the 2023 MLB Draft by the Pirates and debuted in the Majors less than a year later. MLB’s No. 1 pitching prospect brought the heat from the very beginning in his first career start en route to the 2024 NL Rookie of the Year Award, before earning NL Cy Young honors the following year.
Elly De La Cruz, Reds -- June 6, 2023
De La Cruz spent the first three months of the 2023 season treating Triple-A like a video game. He hit a 432-foot walk-off home run, mashed seven balls at least 116 mph and went home to third faster than anyone in MLB. That all led to De La Cruz entering The Show with an almost mythical aura around him heading into his debut. After a solid debut season, he broke out with 25 homers and 67 stolen bases for the Reds in 2024.
Bobby Witt Jr., Royals -- April 7, 2022
After an incredible spring, the Royals decided to add Witt, MLB Pipeline's No. 1 prospect for 2022, to their Opening Day roster. Although the shortstop had an uneven rookie season, he broke out in 2023 and took his game to even greater heights the following year, finishing second in the AL MVP race.
Vladimir Guerrero Jr., Blue Jays -- April 26, 2019
Few prospects have performed better or generated more hype in the Minor Leagues than Guerrero, who also carried on his shoulders the expectations of being a Hall of Famer’s son. The slugger has lived up to the hype, though, becoming the face of the Blue Jays franchise and a perennial All-Star.
Ronald Acuña Jr., Braves -- April 25, 2018
Acuña was MLB’s second-ranked prospect behind Shohei Ohtani, but his arrival came with just as much excitement from Atlanta fans who had seen the 20-year-old tear up Minor League pitching. The five-tool prospect went on to win the NL Rookie of the Year Award in 2018 and bounced back from a torn ACL in '21 to earn NL MVP honors with a historic campaign in '23 (41 HR, 73 SB, 1.012 OPS).
Shohei Ohtani, Angels -- March 29, 2018
Ohtani was perhaps the story of the 2018 regular season thanks to his incredible two-way athletic ability. As someone who could reach triple digits off a pitching mound and hit majestic homers at the plate -- on top of the mystery of climbing up the ranks in Japan, where American fans only heard of his prowess second-hand -- it was hard to create a more compelling narrative. Ohtani has already cemented his place among baseball's all-time greats after six seasons with the Angels and two with the Dodgers, winning four MVP Awards, two World Series titles and producing countless feats that have no parallel in the history of the sport.
Bryce Harper, Nationals -- April 28, 2012
A Sports Illustrated cover story, tales of 500-foot home runs and comparisons to the great Mickey Mantle. Those were the kinds of things accompanying Harper on his way to Dodger Stadium, where he made his debut at just 19 years of age about a year and a half after the Nationals selected him with the No. 1 overall pick. Harper captured Rookie of the Year honors with one of the best teenage seasons in history, won his first MVP Award three years later and added another in 2021 after joining the Phillies in free agency.
RETIRED LEGENDS
Stephen Strasburg, Nationals -- June 8, 2010
Strasburg still has a claim toward the most-hyped prospect of modern times. Labeled by some as the best amateur pitcher ever while at San Diego State, Strasburg went No. 1 to the Nationals in the 2009 MLB Draft and reached the Majors the following year, producing one of the most electric debuts of all time when he struck out 14 Pirates hitters -- including the last seven batters he faced. Injuries were an issue, but Strasburg went on to earn three All-Star selections and won World Series MVP honors after pitching the Nats to a title in 2019.
Ichiro Suzuki, Mariners -- April 2, 2001
Ichiro faced plenty of skepticism as the first Japanese position player to play overseas in America, but that didn't last long. Ichiro's rookie campaign -- which netted him the 2001 AL MVP and was the first of 10 straight 200-hit seasons -- ranks among the absolute best in Major League history. The global hit king with 4,367 professional knocks between NPB and MLB, Ichiro went into the National Baseball Hall of Fame in 2025.
Andruw Jones, Braves -- Aug. 15, 1996
Called up by the defending World Series champions as a 19-year-old in August 1996, Jones became the youngest player to homer in the Fall Classic when he went deep twice against the Yankees in Game 1 later that fall. Ten Gold Glove Awards and 434 home runs later, Jones was elected to the Hall of Fame in 2026.
Hideo Nomo, Dodgers -- May 2, 1995
Featuring a whirlwind windup that earned him the nickname "The Tornado," Nomo made history when he crossed the Pacific Ocean from Nippon Professional Baseball to MLB in 1995. The fanfare, particularly in his native Japan, was enormous. Nomo went on to win the 1995 NL Rookie of the Year Award and was named an All-Star in his first MLB season. He would throw a pair of no-hitters -- including the only no-no thrown at Coors Field -- over a 12-year career that saw him pave the way for dozens of Japanese-born players who came after him.
Alex Rodriguez, Mariners -- July 8, 1994
A-Rod might have been the most complete prospect of the modern era, mixing Major League-ready talent at the plate with speed on the bases and athleticism at shortstop. Although his ties to PEDs complicate his legacy, his career numbers are eye-popping: 696 homers, three MVPs, 14 All-Star selections and a World Series title over 22 seasons for the Mariners, Rangers and Yankees. He also holds the distinction of having signed the first $200+ million deal in professional sports history -- a 10-year, $252 million pact with the Rangers in 2000 -- which he then topped when he signed with the Yankees for $275 million over 10 years after opting out of his previous contract in 2007.
Jim Abbott, Angels -- April 8, 1989
Interest in Abbott’s debut centered around more than just his talent, since Abbott was born without the use of a right hand. He was the top collegiate pitcher at Michigan and had pitched Team USA to a gold medal in the 1988 Olympics before signing with the Angels for $200,000, and then he bypassed the Minors altogether to become just the 17th player in the Draft era to make his professional debut in the Major Leagues. Four years later, while pitching for the Yankees, he threw one of the most memorable no-hitters in MLB history.
Ken Griffey Jr., Mariners -- April 3, 1989
Expectations were sky-high after Griffey -- who grew up in the clubhouses of the Big Red Machine as the son of All-Star outfielder Ken Griffey Sr. -- was taken No. 1 overall by Seattle in the 1987 MLB Draft, and he was the youngest position player to debut in over a decade when he took the field against the defending AL champion A’s on Opening Day in Oakland. He became one of the sport's most iconic superstars during a career that landed him in Cooperstown.
Bo Jackson, Royals -- Sept. 2, 1986
The 1985 Heisman Trophy winner and NFL star ranks among the greatest athletes in professional sports history. Suiting up for the Royals after he was drafted in 1986, Jackson got his first hit off none other than future Hall of Famer Steve Carlton, then a 41-year-old with the White Sox.
Dwight Gooden, Mets -- April 7, 1984
Gooden needed less than two seasons in the Minors before the Mets felt he and his unbelievable stuff were ready for big league hitters. “Doc” climbed the mound at the Astrodome for his debut at just 19 years and 143 days of age and let his high-90s fastball and world-class curveball go to work, striking out five Houston hitters over five one-run innings. His rookie campaign only got better from there, of course, as Gooden finished the year with 17 wins and a freshman-record 276 strikeouts. He was even better one year later, winning the NL Cy Young Award after going 24-4 with a 1.53 ERA and 268 strikeouts.
Darryl Strawberry, Mets -- May 6, 1983
Mets fans hoped that Strawberry, the No. 1 overall pick of the 1980 Draft from Crenshaw High in Los Angeles, would help lift their team out of the NL doldrums -- and Strawberry’s debut did indeed ignite a slow turnaround in Queens. ‘Straw’ was 21 when he debuted at Shea Stadium and drew two walks and scored a run in New York’s 13-inning win over the Reds. He went on to win NL Rookie of the Year honors with a 26-homer campaign before blossoming into one of the league’s most fearsome sluggers of the decade.
Willie Mays, Giants -- May 25, 1951 (AL/NL debut)
Mays’ .477 average led all Triple-A hitters by nearly 100 points when the fifth-place Giants announced that they were calling their prodigious center fielder up to the big league club. Mays’ arrival attracted hordes of African-American fans who didn’t typically attend games at Philadelphia’s Shibe Park, and his pregame practice session drew plenty of eyes -- both for his prowess in the cage and his grace tracking down fly balls in the outfield. Giants manager Leo Durocher put Mays right in the third spot in his batting order, but the “Say Hey Kid” would go hitless in his first 12 at-bats before homering off the great Warren Spahn to get his incredible career off and running.
Mickey Mantle, Yankees -- April 17, 1951
When it comes to mythical, sent-from-the-heavens baseball prodigies, the conversation must begin with Mantle. Born the son of a miner in Oklahoma, Mantle rose from obscurity to become the natural heir to Babe Ruth, Lou Gehrig and Joe DiMaggio in the eyes of Yankees fans thanks to his preternatural speed and, of course, his neck-craning, tape-measure home runs. Mantle nearly quit baseball in 1951 after suffering through a slump, but a stern discussion with his father, Mutt, inspired Mantle to go on an absolute tear with Triple-A Kansas City, finishing his tenure there with a .361 average and 11 home runs in 166 at-bats. The Commerce Comet debuted with a ton of fanfare against the Red Sox at Yankee Stadium and batted third between fellow legends Phil Rizzuto and DiMaggio, kicking off one of baseball’s most revered careers.
Satchel Paige, Indians -- July 9, 1948 (AL/NL debut)
Paige’s stardom was already well established in the Negro Leagues, of course, but he had to wait more than two decades before he could display his talent in the Majors. Paige was arguably the most famous pitcher in America when Indians owner Bill Veeck signed him at age 41 to help his club capture a pennant, and the legend proved that age was just a number by going 6-1 with a 2.48 ERA down the stretch.
Jackie Robinson, Dodgers -- April 15, 1947 (AL/NL debut)
The atmosphere surrounding Robinson’s debut was wholly unlike that of any other player on this list, of course, as he broke Major League Baseball's color barrier. The significance of those circumstances made Robinson’s debut one of the most famous days in modern American history, let alone baseball’s, and it opened the door for thousands of African-American players, including Paige, to follow in his footsteps. Despite facing immense scrutiny and emotional hardship, Robinson captured MLB’s first Rookie of the Year Award and compiled a Hall of Fame career. MLB now honors Robinson's debut with league-wide celebrations every April 15.
Bob Feller, Indians -- July 19, 1936
Feller’s friends in Van Meter, Iowa, were working summer jobs before their senior years of high school when the 17-year-old came on in the eighth inning of the Indians’ 9-5 loss to the Senators in Washington, D.C. His MLB debut included a strikeout, of course, as he worked around a pair of walks for a clean frame, but he really got people’s attention in his first big league start one month later. That’s when “Rapid Robert” struck out 15 Browns hitters and began his tenure as baseball’s most dominant strikeout ace.
Joe DiMaggio, Yankees -- May 3, 1936
DiMaggio, like Mantle, came from humble beginnings and was the son of Italian immigrants in the San Francisco area. Baseball was a way for DiMaggio to escape his father’s profession as a fisherman, and he used that motivation to make a name for himself in the Pacific Coast League, compiling a 61-game hit streak (foreshadowing the future) with the San Francisco Seals. A career-threatening knee injury for DiMaggio didn’t dissuade Yankees scout Bill Essick from signing the kid to a $50,000 contract and he debuted ahead of Lou Gehrig in the Yankees’ lineup at 21 years of age. The rest was history.
