Gallen's been good. He's got a 3.18 ERA and 1.32 WHIP in his first two playoff starts. Wheeler has been better. He's got a 2.59 ERA and 0.72 WHIP for his career in the postseason. In two playoff starts this season, he's got a 2.08 ERA and 0.69 WHIP. Gallen was also just 5-6 with a 4.42 ERA on the road during the regular season. Arizona lost 6-5 when Gallen started against the Phillies. He's got a 4.38 ERA in three career road starts against them. Wheeler has a 2.96 ERA in 11 starts against Arizona. He went 6 or more innings in all 11 of them and allowed 3 or fewer earned runs in 9. I'm going with Wheeler. *home run club
