It's time to talk up Zach Eflin. Based on his early season performance, he's now in the argument for best No. 3 starter. Eflin has a 2.77 ERA with a 19-to-2 strikeout-to-walk ratio in 26 innings. One of the two walks Elfin gave up was intentional. Philadelphia is 10-2 in Eflin's last 12 starts. 

The Cardinals rank 22nd in batting average hitting .222. The Phillies, by comparison, have the seventh-highest batting average in the league at .243. St. Louis has been held to two or fewer runs in five of its last eight games. 

Carlos Martinez will oppose Eflin. Martinez is off his best start in three seasons pitching six innings of one-run baseball against the Nationals five days ago. Martinez, though, still isn't anywhere close to being trusted. He has a 6.00 ERA despite that gem. St. Louis is 0-5 in his last five starts.
