Peacock (1-1) took the loss against Miami on Wednesday, allowing three runs (two earned) on six hits while striking out three over five innings.
Peacock was tabbed for the start after Zac Gallen (elbow) was placed on the 10-day IL earlier in the day. The 27-year-old held his own considering the impromptu nature of the start, but he was done in by a pair of Marlins long balls. Peacock will likely return to the bullpen moving forward.
Peacock will start Wednesday's game against the Marlins, Zach Buchanan of The Athletic reports.
The 27-year-old will make the first start of his big-league career with scheduled starter Zac Gallen (elbow) a late addition to the injured list. Peacock has struggled in his first taste of MLB action this season with eight runs allowed through 11.2 innings. He primarily worked as a starter in the minors but hasn't pitched over two innings since his debut April 6, so he may not go deep into Wednesday's contest.
Peacock was recalled by the Diamondbacks on Friday.
Peacock spent a brief period on the big-league roster earlier in April, allowing two unearned runs on two hits in 5.1 innings. Riley Smith was optioned in a corresponding move.
Peacock was optioned to the Diamondbacks' alternate training site Monday.
Peacock has pitched fairly well in his first three MLB appearances, allowing two unearned runs on two hits in 5.1 innings of work while striking out three and walking two. However, the Diamondbacks had to make room for Zac Gallen's (forearm) return from the injured list. Peacock will likely be back in the big leagues at some point this season.
Peacock (1-0) delivered three innings Tuesday to pick up the win over Colorado in extra innings. He allowed two unearned runs on one hit and one walk while striking out one.
The Diamondbacks depleted their bullpen and needed length from Peacock, who was called up Tuesday to replace the injured Joakim Soria (calf). The 27-year-old was ticketed for low-leverage innings, but he was ultimately needed for important work in extra innings, which, as a minor-league starter, he had the stamina to carry out. He also delivered a base hit in the 13th inning and scored on Ketel Marte's two-run double.
The Diamondbacks plan to call up Peacock from Triple-A Reno ahead of Tuesday's game in Colorado, Bob Nightengale of USA Today reports.
He'll be moving up to the active roster as a replacement in the bullpen for Joakim Soria (calf), who is expected to be placed on the 10-day injured list later Tuesday. Peacock, a 27-year-old right-hander who has yet to pitch above the Double-A level, will likely be ticketed for low-leverage duties out of the bullpen.
The Diamondbacks optioned Peacock to Triple-A Reno on Sunday, Steve Gilbert of MLB.com reports.
Arizona thought enough of Peacock's potential to protect him from the Rule 5 draft this winter, but the 27-year-old right-hander wasn't considered a serious threat to break camp with the big club. He'll get his first taste of Triple-A to begin the 2021 campaign after he submitted a 2.97 ERA, 1.21 WHIP and 81 strikeouts in 115.1 innings at Double-A Jacksonville in 2019.
