Blue Jays Acquire Chase Lee

The Tigers have traded right-hander Chase Lee to the Blue Jays in exchange for minor league lefty Johan Simon, according to announcements from both clubs. This move is likely to open a 40-man spot for the Tigers to make their signing of Kyle Finnegan official. The Jays had a 40-man vacancy but Lee takes up the final spot. Ken Rosenthal and Will Sammon of The Athletic first reported that Lee was headed to the Jays while Mitch Bannon of The Athletic first mentioned Simon as the return.

Lee, 27, doesn’t throw especially hard but is able to deceive batters with his sidearm delivery. Originally a draft pick of the Rangers, he was traded to the Tigers as part of the 2024 deadline deal which sent Andrew Chafin the other way.

In 2024 2/3 minor league innings, Lee has allowed 4.13 earned runs pere nine, with a fairly average 8% walk rate but a strong 30.9% strikeout rate. The Tigers called him up to make his major league debut in 2025. He gave them 37 1/3 innings with a 4.10 ERA. His four-seam fastball only averaged 89.2 miles per hour while he also threw a sinker, slider and changeup. He struck out 24.3% of opponents while limiting walks to a 6.1% clip.

For the Jays, Lee adds some extra bullpen depth. He still has options and can therefore be sent to Triple-A Buffalo and back throughout the year. Shi Davidi of Sportsnet recently wrote a piece about how the Jays appear to be prioritizing different arm angles, so it’s possible they are particularly attracted to Lee’s sidearming abilities. He has less than a year of service time and is therefore years away from qualifying for arbitration and even further from free agency. If he’s able to carve out a meaningful role in the big leagues, he could be a long-term piece for the Jays.

To get Lee, the Jays are giving up Simon, an international signing out of the Dominican Republic. In 2025, he began at Single-A and then climbed to High-A and Double-A. Across those three levels, he tossed 71 relief innings with a 3.42 ERA, 25.1% strikeout rate, 9.2% walk rate and a massive 64% ground ball rate.

For the Tigers, they had a 40-man roster crunch and needed to lose someone. With this deal, they’ve lost a bit of immediate depth but replaced Lee with a non-roster arm who is only slightly farther away from the majors.
