In February, MLB Pipeline's experts attempted to predict which Minor Leaguers would make Opening Day rosters by assigning likelihood percentages to several Top 100 prospects.
Jim Callis and Jonathan Mayo gave 100 percent chances to five different prospects, four of whom have already made their MLB debuts. They also pegged the Cardinals' JJ Wetherholt for a starting spot, which he nabbed on Monday.
We're getting closer to having all the official results.

Here's a breakdown of Top 100 prospects who have been in big league camp this spring and their expected outcomes:
Konnor Griffin, SS (PIT No. 1/MLB No. 1)
Griffin’s two-homer game in his third contest of the spring prompted significant buzz about his chances of cracking the Pirates’ Opening Day roster. As Spring Training progressed, though, the strikeouts started piling up for the 19-year-old phenom and his case got weaker. It's not out of the question that he reaches the Majors in 2026, but the Pirates opted to send Griffin to Triple-A to start the year.
Kevin McGonigle, SS (DET No. 1/MLB No. 2)
McGonigle’s defense -- a lingering question coming into Spring Training -- has been the talk of Tigers camp. Over 19 games this spring, the reigning Arizona Fall League MVP has split time between shortstop and third base, showing he has the fielding chops to match his electric bat. At the dish, his elite hit tool has been as advertised. McGonigle has a .923 OPS with two homers across 40 Grapefruit League at-bats and more walks (11) than strikeouts (eight).
JJ Wetherholt, INF (STL No. 1/MLB No. 5)
The seventh overall pick in the 2024 Draft, Wetherholt made his mark in his second big league camp. He even was able to take time out to score All-Spring Breakout Second Team honors en route to earning the job as the Cardinals' starting second baseman on Opening Day. The West Virginia product -- who sports a 65-grade hit tool -- tallied two homers while collecting nine walks (with seven strikeouts) in 44 plate appearances this spring.
Nolan McLean, RHP (NYM No. 1/MLB No. 6)
McLean endeared himself to Mets fans last season after posting a 2.06 ERA and a 1.04 WHIP with 57 strikeouts over eight big league starts between August and September. The successful MLB audition earned the former two-way player a Team USA invite for the World Baseball Classic and secured him the No. 3 spot in the Mets’ starting rotation for the upcoming season. McLean produces elite spin rates resulting in a pair of devastating plus breaking pitches.
Samuel Basallo, C/1B (BAL No. 1/MLB No. 8)
A catcher by trade, Basallo projects to start as the Orioles’ designated hitter on Opening Day because of the offensive boost his bat provides -- and the presence of All-Star backstop Adley Rutschman. Over 15 games this spring, the 21-year-old Basallo has three homers and a 1.114 OPS.
Colt Emerson, SS (SEA No. 1/MLB No. 9)
While some considered Emerson an option to fill in for veteran shortstop J.P. Crawford while he deals with a shoulder injury, the Mariners felt they would be doing the 20-year-old a disservice by using him as a placeholder. The 2023 first-rounder will report to Triple-A Tacoma to start the year after posting an .828 OPS with two homers in Spring Training.
Bubba Chandler, RHP (PIT No. 2/MLB No. 11)
Chandler made seven big league appearances last season, flashing a high-velocity four-seamer that averaged 98.9 mph and reached 102. The offering is a true elite pitch and pairs well with the 2021 third-rounder’s low-90s changeup. Chandler’s strongest start of the spring came on March 12, when he threw 18 straight four-seamers (49 total) and racked up eight punchouts over five innings. He projects to enter 2026 as the Buccos’ No. 5 starter.
Trey Yesavage, RHP (TOR No. 1/MLB No. 12)
Yesavage made the unprecedented climb from the Blue Jays’ Single-A affiliate all the way to the Majors in his first professional season. Then after three starts, he became a pivotal piece in Toronto’s run to the World Series. The 2024 first-rounder was projected to open the season in the club’s starting rotation, but will now begin the year the IL with a right shoulder impingement.
Carson Benge, OF (NYM No. 2/MLB No. 16)
As Juan Soto shifted to left field for the 2026 season, right field opened up for Benge. The 23-year-old made the Opening Day roster after hitting .366/.435/.439 with a triple, a double and a stolen base over 46 spring plate appearances. Benge figures to hit near the bottom of New York’s lineup at first -- likely the eight-hole, where he has been spending the final days of Spring Training.
Carter Jensen, C (KC No. 1/MLB No. 18)
The Kansas City native stayed nearby when he went in the third round of the 2021 Draft. After 20 games with the Royals last year following backup catcher Freddy Fermin's trade to the Padres, Jensen emerged as the next backstop working in tandem with the veteran Salvador Perez. With nine starts as a designated hitter in 2025, Jensen -- who slugged three homers this spring -- is poised for more opportunities behind the plate in his first full season.
Payton Tolle, LHP (BOS No. 1/MLB No. 19)
Tolle made the big leagues last season with just 91 2/3 Minor League innings under his belt thanks to his 70-grade fastball and elite extension. He made four starts for the Red Sox before moving to the bullpen for his final four appearances and the playoffs. This spring, Tolle once again showcased his strikeout stuff, combining for seven scoreless frames with 12 K's over his final two outings. But due to Boston's starting pitching depth he will start the year at Triple-A.
Sal Stewart, 1B/3B (CIN No. 1/MLB No. 22)
Primarily a third baseman during his time in the Minors, Stewart slid over to first for the majority of his 18-game MLB debut because Cincinnati wanted to find a way to fit his bat in the lineup. The 2022 No. 32 overall pick proved the club right with five homers over that span. Stewart has been similarly productive this spring (1.065 OPS, three homers) and projects to man the cold corner on Opening Day.
Bryce Eldridge, 1B (SF No. 1/MLB No. 25)
At 6-foot-7 and 251 pounds, Eldridge has titanic power, but the Giants opted to send him to Triple-A to start the season because of the more nuanced parts of his game. First-year MLB manager Tony Vitello cited Eldridge’s defense and baserunning as skills that could use improvement, and with first base already occupied by Rafael Devers, the club feels it can slow play Eldridge’s development.
Andrew Painter, RHP (PHI No. 2/MLB No. 28)
Painter will start the season in Philadelphia’s rotation while Zack Wheeler continues to work his way back from thoracic outlet decompression surgery. Last season was a mixed bag for Painter, as it marked the 6-foot-7 hurler's first full season since undergoing Tommy John surgery in 2023. This spring, Painter looked closer to his pre-surgery self. He allowed three runs while striking out eight over 11 2/3 innings (four starts).
Owen Caissie, OF (MIA No. 3/MLB No. 42)
Acquired by Miami as part of the package for Edward Cabrera this past winter, Caissie projects to be the primary right fielder for his new club. The 23-year-old crushed 22 homers at Triple-A last season and appeared in 12 big league games with Chicago.
Chase DeLauter, OF (CLE No. 2/MLB No. 46)
DeLauter became one of just six players to make his MLB debut in the postseason when he took the field in Game 2 of the American League Wild Card series last fall. In 2026, he'll have the chance to make an impact with a bit less pressure. The 2022 first-rounder is in line to open the season as part of the Guardians' outfield mix after slashing .459/.535/.838 so far this spring.
Jonah Tong, RHP (NYM No. 3/MLB No. 48)
The 22-year-old righty -- who will graduate from prospect status with one more day on the active roster -- will start the year at Triple-A. While making his big league debut in the final stretch of the 2025 season, Tong surrendered six earned runs across seven frames this spring, but he struck out seven to his lone walk.
Jett Williams, SS/2B/OF (MIL No. 3/MLB No. 51)
The headlining prospect in the return for Willy Peralta from the Mets, Williams was reassigned to Minor League camp, seemingly projected to start the year at Triple-A. The 5-foot-7 righty and 65-grade runner legged out a triple and stole two bases while slashing .353 /.476/.588 this spring for the Brewers.
Justin Crawford, OF (PHI No. 3/MLB No. 53)
Crawford won the Phillies' starting center-field spot after making 17 starts at the position in Spring Training. The son of four-time All-Star Carl, Justin possesses elite speed like his father with a 75-grade run tool. The 2022 first-rounder swiped over 40 bases each of the past three seasons in the Minor Leagues.
Moisés Ballesteros, C (CHC No. 1/MLB No. 55)
While making 16 of his 17 starts in 2025 as a designated hitter, Ballesteros is expected to fill a similar role after cracking his first Opening Day roster. Although most of his Spring Training starts (seven) have come behind the dish, he will receive the bulk of his plate appearances as the DH, providing depth behind Carson Kelly and Miguel Amaya at catcher and Michael Busch at first base. Ballesteros -- who slashed .298/.394/.474 with two homers in 20 games last season -- posted a 1.056 OPS with two homers and five doubles in 15 contests this spring.
Connelly Early, LHP (BOS No. 3/MLB No. 56)
While Red Sox counterpart Payton Tolle got reassigned to Minor League camp, Early earned his nod for the Opening Day roster, although his role has yet to be announced. In the Grapefruit League, the 2023 third-rounder out with a 60-grade changeup notched 16 strikeouts across 17 innings this spring with a 1.59 ERA, a 0.94 WHIP and a .180 average-against. The southpaw started for Boston in last year's Wild Card series.
Carson Williams, SS (TB No. 1/MLB No. 63)
After finishing the 2025 season in the big leagues, Williams entered Spring Training not only battling for a starting job, but a roster spot as well. The Rays optioned the 2021 first-rounder after he hit .281 across 15 games this spring, but with shortstop Taylor Walls suffering an oblique injury, it has opened the door for Williams to possibly be recalled.
Dylan Beavers, OF (BAL No. 2/MLB No. 69)
Although scratched from the Orioles’ lineup with knee discomfort Friday, Beavers doesn’t expect to miss Opening Day. The left-handed-hitting outfielder, who made his big league debut in August, posted a .485 slugging percentage with six extra-base hits across 11 games this spring. The California product sports a 60-grade run tool.
Harry Ford, C (WSH No. 3/MLB No. 71)
After moving out of the Mariners system, where AL MVP runner-up Cal Raleigh blocked his opportunity at catcher, Ford landed in the nation’s capital as the headliner in the return for Jose A. Ferrer. But with Keibert Ruiz and Drew Millas both poised to make the Opening Day roster, Ford will start the year at Triple-A in order to get regular playing time.
Rhett Lowder, RHP (CIN No. 4/MLB No. 86)
The seventh overall pick in the 2023 Draft, Lowder fast-tracked to the big leagues in his first full professional season before injuries derailed his 2025 campaign, which didn’t include an outing in the Majors. The Wake Forest product cracked this year's Opening Day roster while competing for starts in a rotation dealing with injuries to Hunter Greene, Nick Lodolo and Brady Singer.
Parker Messick, LHP (CLE No. 5/MLB No. 95)
In his first big league Spring Training, Messick came away with the fifth spot in the Guardians’ rotation. The lefty selected in the second round out of Florida State in 2022 started seven games for Cleveland last year, sporting a 2.27 ERA and a 1.31 WHIP in 39 2/3 innings. Messick didn’t make an appearance in the postseason.
Hunter Barco, LHP (PIT No. 5/MLB No. 96)
After a short stint out of the bullpen in 2025, the southpaw cracked the Pirates’ Opening Day roster as a reliever to start the season -- an approach taken with Chandler and Braxton Ashcraft as well. The 2022 second-round pick started two of his five Grapefruit League appearances, compiling 15 strikeouts to eight walks in 11 2/3 total innings.
Brandon Sproat, RHP (MIL No. 5/MLB No. 100)
Acquired from the Mets in the Peralta deal this past offseason, Sproat made four starts in his first cup of coffee in the big leagues in 2025. The 2023 second-rounder out of Florida cracked the Opening Day rotation for the Brewers after racking up 10 strikeouts in nine spring frames.
