Winans was recalled from Triple-A Gwinnett to start the first game of Saturday's doubleheader against the Mets.
Winans was appointed as the 27th man for the twin bill, which likely means he'll return to the minors immediately after his start. The 27-year-old righty made his big-league debut in late July, allowing two runs on five hits in 4.1 innings against the Brewers.
