Detroit Tigers reliever Alex Wilson has outlasted the two other pieces acquired with him from Boston (Yoenis Cespedes and prospect Gabe Speier), quietly establishing himself as one of baseball’s most effective relievers.
He won’t blow anyone away with his fastball or miss a ton of bats (8.9 swinging strike percentage), but it is clear that Wilson knows how to get batters out.
The reliever has registered ERAs under three in each of his first two seasons, including a 2.96 number last season. While Wilson’s 4.33 SIERA and 4.58 xFIP aren’t necessarily anything to write home about, he did pitch exceptionally well after some initial struggles.
