Peacock to start for Astros on Sunday
Peacock is 6-2 with a 2.73 ERA in the minors. The Astros need him after Dallas Keuchel, Sunday's originally scheduled starter, pitched in a 13-inning loss to Minnesota on Saturday night.
Manager Bo Porter could have started Lucas Harrell on Sunday, but said he needed him in the bullpen.
Peacock has appeared in nine games with the Astros this season - five of them starts - and is 1-3 with an 8.07 ERA. A corresponding roster move will be made before Sunday's game.
Second baseman Jose Altuve returned to the lineup Saturday after missing two games with a sore left quad.
