Trevor Bauer will make his major league debut for the Diamondbacks on Thursday, according to sources. Bauer, who has dominated minor league hitters at two levels this season, was pulled after making 50 pitches in 2 2/3 innings in his start for Class AAA Reno on Sunday. He is 11-1 with a 2.23 ERA in 16 starts and leads minor league pitchers with 116 strikeouts after getting five Sunday. "Soon," a source said when asked when Bauer would join the team.
