2026 Projections
Signed a one-year contract with the Rays in March of 2025. Traded to the Pirates in December of 2025.
Lands with Pirates in trade
The Pirates acquired Montgomery from the Rays on Friday in a three-team trade, Chandler Rome and Ken Rosenthal of The Athletic report.
Analysis
Montgomery logged a 5.67 ERA and walked 27 over 46 innings with the Rays in 2025, but he also struck out 63 batters and, at 98.7 mph, has one of the hardest average four-seamer velocities in the game. The lefty has past starting experience, but the Pirates are likely to keep Montgomery in the bullpen, and he could work his way into high-leverage appearances.

Past Fantasy Outlooks
2025
2024
2023
Montgomery was once a highly rated prospect in the Rays organization, but he was becoming increasingly more hittable as he moved up in the organization, and the club decided to move him to the pen after a July 12th loss left him 0-6 with a 6.62 ERA in the Durham rotation. Montgomery then went on to work in the bullpen for the Bulls where he struck out 30 in 18.1 innings of work and earned a promotion to the big leagues in early September. Montgomery went on to strike out 17 of the 37 batters he faced in September with a new-found upper 90s fastball and sharp slider. Simply put, Montgomery has found his new home in the bullpen as someone who can come in and get punches when needed and should be particularly tough on lefties with his fastball/slider combination if he and the club choose to pair down his offerings to that combination. As it stands now, he could be the primary lefty out of the pen in high-leverage situations with the departure of Colin Poche who previously held that role.

Latest Fantasy Rumors
Appears destined for Pittsburgh
The Pirates, Astros and Rays are in talks about a three-team trade that would send Montgomery to Pittsburgh, Ken Rosenthal of The Athletic reports.
Analysis
The Pirates would also receive Brandon Lowe and Jake Mangum as part of a six-player deal. Montgomery finished with a 5.67 ERA with the Rays in 2025, but he struck out 63 over 46 innings and is one of the hardest throwers in the game with an average four-seamer velocity of 98.7 mph. The lefty would likely be pegged for late-inning work in Pittsburgh.
