Eflin moved to 5-0 with seven scoreless innings Wednesday for Triple-A Lehigh Valley. He allowed two hits and one walk while striking out six.
Eflin lowered his ERA to 2.36 and now has a 39:7 K:BB in 45.2 innings. He has increased his K/9 to 7.7 this season after averaging just 4.7 K/9 last season at Double-A Reading. Eflin told Sam Dykstra of MiLB.com that better fastball command and learning how to setup hitters are the primary reasons for the spike in his strikeout rate this season. He'll be under strong consideration for a promotion to the majors the next time the Phillies need a starting pitcher.
