The Guardians traded Strzelecki to the Pirates on Friday in exchange for cash.
Strzelecki was designated for assignment Tuesday in order to make room for Franco Aleman on the Guardians' 40-man roster, but the former will now claim a spot on Pittsburgh's 40-man upon switching organizations. The 30-year-old put up a 5.01 ERA and 1.39 WHIP across 46.2 innings in the minors last season, and he will compete for a spot in the Pirates' bullpen during spring training.
