The Tigers designated infielder Eddys Leonard and relievers Ricky Vanasco and Brendan White for assignment. Their spots on the 40-man roster will go to righties Chase Lee, Tyler Mattison and Tyler Owens. Detroit kept that trio out of next month’s Rule 5 draft.
Leonard has held a spot on Detroit’s 40-man roster since they acquired him in a minor trade with the Dodgers in August 2023. The 24-year-old infielder hit .253/.320/.435 between three minor league levels this year. He hasn’t appeared in the majors. Vanasco also landed in Detroit via a small trade with Los Angeles — this one coming this past July. He pitched two scoreless innings at the major league level and has four career appearances. White, who turned 26 yesterday, pitched to a 5.03 ERA across 40 2/3 innings as a rookie in 2023. He spent most of this season on the minor league injured list.
The three players joining the roster are all upper level bullpen arms. Lee, an Alabama product, came over from the Rangers at this year’s deadline in the Andrew Chafin trade. The 26-year-old righty turned in a 2.75 ERA across 36 innings between the two organizations. He punched out 30% of batters faced with a tidy 6.8% walk rate.
Mattison, a 6’4″ pitcher out of Bryant, posted excellent strikeout numbers this year. He fanned nearly 38% of hitters en route to a 2.41 ERA across 59 2/3 innings between High-A West Michigan and Double-A Erie. While the 25-year-old was a bit more advanced than most hitters he faced, he pitched well enough that another team could’ve tried to stash him in the middle innings.
Owens, 24 in January, has been traded twice since entering pro ball as a 13th-round pick in 2021. Originally an Atlanta draftee, he went to the Rangers last offseason for outfielder J.P. Martínez. Texas dealt him to Detroit as part of the Carson Kelly deadline deal. The 5’10” hurler put up a 2.96 ERA while striking out just over a quarter of opponents in Double-A this year.
