The announcement of Peter Moylan’s retirement came from David O’Brien of The Athletic. He does mention that the reliever will be pitching for a pro team in Italy with the intention of pitching for Australia in the Olympics. Moylan spent nine of his 12 years in the MLB as a member of the Atlanta Braves, and two for the Kansas City Royals.
Kansas City got Moylan in 2016 and 2017, ages 37 and 38. In each of those seasons he made at least 50 appearances and posted an FIP of 4.00. In 2017, his 79 appearances led the entire league.
