Chase Lee is a 27-year-old, side-arm, right-handed reliever we picked up in trade from the Tigers in December. The Tigers needed a spot on the 40-man roster. And I had totally forgotten he was on the 40-man. I think this is the first one I totally forgot about. I’m not sure if this is true, but I’ve always felt that side-arm pitchers can continue to be effective into their late-30s.
The Jays sent Johan Simon to the Tigers, a 24-year-old left-handed pitcher who spent most of 2025 with Vancouver. He throws a 94 MPH fastball and gets a lot of ground balls. He had a 3.42 ERA across three levels last year. Not a big prospect but could make it as a lefty reliever.
Lee has two option years left, which gives him more value to the Jays. He pitched in 32 games as a reliever for the Tigers, with a 4.10 ERA, 9 walks, 36 strikeouts in 37.1 innings with 7 home runs against. Batters hit .239/.291/.478 against him. Statcast says he averaged 89.1 on his fastball.
He throws a sinker, sweeper, 4-seem and an occasion change up.
He also had 32 innings in Toledo with a 6.75 ERA in 32 innings, with 38 strikeouts, 10 walks and 4 home runs.
FanGraphs had Lee at #29 on their top 39 Tigers’ prospect list (39 seems a strange number). They said:
Lee, who came to Detroit from Texas in the Andrew Chafin deal, is a pretty standard sinker/slider sidearmer who has posted strikeout rates up around 30% his entire minor league career while maintaining a below-average walk rate. He doesn’t have precise fastball control — he lives in the zone, but not always on the edge of it — and that might be a problem against big leaguers when you’re only sitting 88. But both Lee’s sinker and slider live in the bottom of the zone consistently enough to consider him a high-probability up/down look reliever.
Bless You Boys had him #37 on their list:
Lee is a sidearm reliever who rarely tops 91 mph, but his mix of fastball types and sweeper-slider combination makes him a tricky at-bat, especially for right-handed hitters. The Rangers certainly thought so when they spent the second pick of the sixth round of the 2021 draft on the reliever out of Alabama. He racked up a ton of strikeouts in their farm system and limited home runs, but trouble with walks kept him from breaking through at the major league level.
Against right-handers, Lee will also use a heavy volume of sweepers. Against lefties he’ll mix his slider in almost as much as the sweeper. The sweeper is typically around 80-81 mph, with a lot of horizontal movement out of that low, side arm slot. Right-handers are consistently seeing the sweeper start in their hot zones, beginning their swing, and then flailing as the pitch bends all the way across the strike zone to be buried down and away. He’s racked up a solid but unspectacular whiff rate of 28.3 percent with it at the Triple-A level going back to the beginning of the 2024 season. The slider has more depth and is typically 84 mph. He uses it a little more when he needs to throw something that’s a change of pace for a strike.
As Lee is likely to be used as right-handed hitter specialist for the most part at the major league level, it’s the sinker-sweeper combination that you’re likely to see most from him. However, the slider and fourseamer give him extra weapons to work with against lefties, and he’s handled them pretty well too. He’s just more home run prone against southpaws and not the guy you want facing Shohei Ohtani and Freddie Freeman in an outing, as an extreme example.
For the Jays, I think a lot of his value is the arm angle and the options. You can see the arm angle here:
Steamer thinks he’ll pitch 30 games, 30 innings, with a 3.92 ERA, 29 Ks, and 10 walks.
