Pirates designated RHP Trey Haley for assignment.
The 25-year-old right-hander has struggled at Triple-A Indianapolis this season, registering a 6.66 ERA, 1.89 WHIP and 19/20 K/BB ratio across 24 1/3 innings. There’s a decent chance he passes through waivers unclaimed and will continue to function as bullpen depth for the Pirates.
