Top prospect Trevor Bauer will make his major-league debut with the Arizona Diamondbacks on Thursday, Fox Sports Arizona's Jack Magruder reported.
Bauer was the third overall pick in last year's MLB Draft, and he has dominated minor-league competition so far this year. He'll likely take over for Joe Saunders, who was placed on the disabled list on Sunday with left shoulder inflammation. Bauer was taken out of his start Sunday after 50 pitches, and Magruder reported that it was not due to injury.
Diamondbacks manager Kirk Gibson spoke "generally" about Bauer on Saturday, and it's clear that he is at least impressed with the 21-year-old Bauer.
"There are certain things he does great. We all know he has great stuff. His last two starts, he has had 100 pitches in five innings. If I was Trevor, I can tell you, when I was a big leaguer, I would argue that I would get better with better competition. I think that’s how he probably thinks. I don’t know that we know that answer."
Bauer is a combined 11-1 with a 2.23 ERA at Double-A and Triple-A this season. With the Triple-A Reno Aces, he was 4-0 with a 2.82 ERA. He has struck out 56 batters in just 44 2/3 innings. Baseball America rated Bauer as its No. 9 prospect going into the 2012 season.
