Peralta is one of three options to win the Brewers' fifth starter job, Will Sammon of The Athletic reports.
He will be competing with Corbin Burnes and Eric Lauer. The Brewers could conceivably go with a six-man rotation where it's a tandem start on the sixth day, or they could just be very conservative with how deep they let the non Brandon Woodruff starters go. Peralta signed a five-year, $15.5 million contract extension in February, which should make it easier for him to accept any role the Brewers assign him for 2020.
