All three runs allowed by Ryu have come on two homers, including a two-run homer by a Giants pitcher in Ryu's last start. Meanwhile, Mikolas has allowed four homers in his first 10 innings this season after serving up only 16 homers in 32 starts last season. While the 30-year-old Mikolas was a natural pick to be the Cardinals Opening Day starter after going 18-4 with a 2.83 ERA last season and finishing sixth in the National League Cy Young Award voting, Ryu was actually the Dodgers' fourth choice.
