The Blue Jays announced they’ve re-signed lefty reliever Joe Mantiply to a minor league contract. The ISE Baseball client receives a non-roster invite to MLB camp.
Mantiply finished last season in the Toronto organization. Released by the Diamondbacks in June, he signed a minor league deal with the Jays shortly after the All-Star Break. Mantiply spent a couple weeks building up at the team’s Florida complex before reporting to Triple-A Buffalo. He finished the season with the Bisons, allowing eight runs (six earned) across 15 2/3 innings.
The run prevention was unexceptional, but Mantiply posted a 19:0 strikeout-to-walk ratio against 64 Triple-A opponents. It didn’t get him a big league look. The Jays were impressed enough to bring him back on an NRI after he elected minor league free agency over the offseason.
Mantiply was a surprise All-Star in 2022 — a season in which he posted a 2.85 ERA across a career-high 60 innings. The 35-year-old southpaw has strong command and gets grounders but has below-average velocity. Mantiply averaged 88.4 mph on his sinker last year. He gets good movement on the sinker and his changeup and was a solid middle reliever as recently as 2024. He was knocked around for 17 runs in 9 2/3 MLB frames last year.
The Jays have one of the better rosters in MLB but are light on established left-handed relief. Eric Lauer is set for a multi-inning role. Mason Fluharty is a soft-tossing cutter specialist, while Brendon Little has much bigger raw stuff. Both pitchers can miss bats but aren’t reliably around the strike zone. Ricky Tiedemann could factor into the rotation or relief mix as a rookie, but the oft-injured former top prospect is again battling elbow discomfort early in camp.
