Mason Montgomery Fantasy Stats

Pittsburgh Pirates left-handed reliever Mason Montgomery is pushing into the ninth-inning conversation as the club mixes its late-inning assignments. Montgomery struck out the side in a non-save ninth against Philadelphia on July 2, one inning after Gregory Soto handled the top of the order. The 26-year-old has a 4.50 ERA and 1.35 WHIP through 34 innings, but his 50 strikeouts are the main reason to speculate on him. No one has taken control of the job. Montgomery still has zero saves, Soto owns 11, and Dennis Santana has two, so fantasy managers are betting on the next opportunity rather than a settled role. FanGraphs lists all three in the closer committee, while RotoBaller recommends Montgomery in 12-team leagues. He is rostered in only 1% of Yahoo leagues and is worth adding for saves speculation, though managers should expect uneven ratios and a committee for now.

Pittsburgh Pirates left-handed reliever Mason Montgomery and right-hander Dennis Santana have risen up the closer depth chart in Pittsburgh with lefty Gregory Soto struggling of late. Montgomery was afforded a couple of save opportunities in June, but the problem is he blew both of his save chances and struggled to a 6.52 ERA (3.00 FIP) with seven earned runs allowed on 11 hits (one homer) while walking six and striking out 16 in 9 2/3 innings with a 1-2 record, two blown saves, and a hold. Overall in 2026, the 26-year-old former sixth-round pick by the Tampa Bay Rays in 2021 out of Texas Tech University has gone 2-3 with a 4.68 ERA (3.35 FIP), 1.41 WHIP, and 46:16 K:BB in his 32 2/3 innings pitched across 33 outings (four starts) for the Bucs. While Montgomery is a late-inning option for the Pirates in their constantly evolving bullpen, he just hasn't been consistent enough in high-leverage situations for fantasy managers to trust as a source of saves in mixed leagues. Montgomery is rostered in just 1% of Yahoo leagues.

The Tampa Bay Rays report that left-handed pitcher Mason Montgomery has been sent down to Triple-A. In a corresponding move, right-handed pitcher Mason Englert was recalled to the big-league squad. Montgomery pitched well in 2024 when first called upon, but compiled an ugly 5.74 ERA and 1.77 WHIP through 40 appearances (31 1/3 innings) in 2025 despite good swing-and-miss stuff. He'll get some time to work things out in the lower levels. Englert pitched for Tampa Bay earlier this season, but hasn't since mid-June. He performed much better in the minors (1.23 ERA) this year than he did in the majors (4.84), so maybe his demotion was a productive one. He'll slot into the former's vacated spot in the bullpen.

The Tampa Bay Rays selected the contract of left-handed pitching prospect Mason Montgomery from Triple-A Durham on Thursday and also recalled infielder Austin Shenton from Durham. In corresponding moves, the club designated catcher Alex Jackson for assignment and optioned left-hander Tyler Alexander to Durham. Montgomery began the 2024 season in the minors as a starter, but since being shifted to the bullpen recently at Durham, the 24-year-old southpaw has been much better, tossing 9 2/3 scoreless frames out of the bullpen with 20 strikeouts and only five walks. The former sixth-round pick in 2021 out of Texas Tech went 1-7 overall for Durham with a 6.26 ERA, a 1.61 WHIP and a 105:36 K:BB in 31 outings (14 starts). He'll most likely start in a relief role but could be an interesting arm in holds leagues in 2025 if he works his way into a high-leverage role in Tampa's 'pen.

Tampa Bay Rays starting pitching prospect Mason Montgomery will look to improve in his fourth start of the season on Tuesday for Triple-A Durham. The left-hander has been off to a rocky start this season with a 10.80 ERA in three starts and has gotten worst in each outing. The lefty is the Rays top pitching prospect and has quickly risen through the system. Walks have been an issue for him in the past, but this year he has just three in 10 innings with 10 strikeouts. Despite being the clubs top pitching prospect, he is just inside their top 10 prospects overall. With his struggles and the Rays set with their rotation at the moment, Montgomery can remain on the waiver wire in all formats.
