COMSTOCK PARK, Mich. — Shuffling through the dugout in a T-shirt, shorts, tights, and sandals, Mike Sirota flashes a grin, followed by a firm handshake. Still just 22 years old, there is an immediate ease emitting from Sirota as he takes a seat and stares out at the field. He had been through the Midwest League before, but this time he’s healthy, and for Sirota, he’s taking the journey and challenges all in stride.
