Peterson (3-1) picked up the win in Thursday's 8-2 victory over the Nationals, allowing one unearned run on one hit and two walks over five innings. He struck out three.
Peterson continued his steady start to his big-league career Thursday. The left-hander has logged at least five innings and allowed three runs or fewer in each of his four starts. It's important to note that the southpaw only threw 74 pitches due to shoulder soreness, according to Newsday Sports. Peterson described the soreness as "nothing to worry about," which indicates he thinks he'll be ready for his start against the Marlins next week.
