Marlins starter Phelps leaves with right elbow discomfort
Phelps, who entered the game with a 4-8 mark and a 4.35 ERA, gave up two home runs to Jason Heyward. After the second homer, he delivered one pitch to Randal Grichuk and then signaled for the trainer to come to the mound.
Left-hander Chris Narveson replaced Phelps, who gave up three runs on four hits in 2 1-3 innings.
Phelps grew up in the St. Louis suburb of Hazelwood.
