Thomas Hatch is officially a Major League Baseball player.
The former Oklahoma State standout did not allow a hit, struck out three and walked two in 2 1⁄3 innings for the Blue Jays in his MLB debut in a 6-5 loss in 10 innings to the Rays on Sunday at Rogers Centre.
Hatch, who was acquired from the Cubs for veteran reliever David Phelps on July 30, 2019, started to throw his changeup more often after working with former Double-A pitching coach Vince Horsman in New Hampshire.
