SEATTLE -- Just hours before highly touted third baseman Rafael Devers made his Major League debut for the Red Sox on Tuesday night at Safeco Field, he vaulted to the No. 4 spot in MLBPipeline.com's Top 100 midseason rankings.
The left-handed-hitting slugger was ranked 17th in the preseason before a breakout half-season in the Minors (.311/.377/,578) led to his callup on Monday.
• Red Sox Top 30 Prospects
Devers, 20, hopes to give the Red Sox more firepower for an offense that has struggled to score of late.
Jay Groome, the ultra-talented lefty the Red Sox drafted out of high school in 2016, gives Boston two players in the Top 100. Groome, who returned recently after a prolonged absence due to a lat injury, is ranked No. 48.

Based on the points system for players in the Top 100, the Red Sox rank 19th among the 30 MLB teams with 150 points. Devers gets 97 points for his No. 4 ranking, while Groome notched 53.
Back in December, the Red Sox packaged current No. 1 prospect Yoan Moncada along with No. 12 Michael Kopech to the White Sox in a deal for ace Chris Sale. That was a deal Boston would do again, as Sale is currently a heavy favorite to win the American League Cy Young Award and is under the club's control at reasonable cost through 2019.
While Devers and Groome rank 1-2 in Boston's re-ranked Top 30, third baseman Michael Chavis has taken an impressive leap to No. 3, up eight spots from where he was in the preseason.
After a blistering first 59 games of the season at Class A Salem, Chavis was promoted to Double-A Portland on June 23. His combined numbers for the two affiliates include a .302 average, 23 homers, 71 RBIs and a .949 OPS. The right-handed hitter was drafted by the Red Sox with the 26th overall pick in the 2014 Draft.
Sam Travis, the second-rounder from '14, holds down the fourth spot. The first baseman handled himself well in multiple stints for the Red Sox this season, hitting .279 with five doubles and a homer in 43 at-bats.
Tanner Hauck, the hard-throwing righty from the University of Missouri who was a first-rounder in this year's Draft, makes his Pipeline.com debut as the Red Sox's No. 5 prospect.

Daniel Flores, the catcher who was Boston's top prize during the international free-agent signing period earlier this month, is No. 6.
The ranking of baseball's top prospects is done by MLBPipeline.com Draft and prospect experts Jonathan Mayo, Jim Callis and Mike Rosenbaum, who compile input from industry sources, including scouts and scouting directors. It is based on analysis of players' skill sets, upsides, proximity to the Majors and potential immediate impact to their teams. Only players with rookie status are eligible for the list. Players who were at least 23 years old when they signed and played in leagues deemed to be professional (Japan, Korea, Taiwan, Cuba) are not eligible.
