Pelfrey's worst start this season came against these same Philadelphia Phillies back on May 1 at Citizens Bank Park, when he allowed six runs in just four innings in a 10-0 loss (his lone defeat of the season). But at home, he has been spectacular, with a 4-0 record in six starts with a 2.43 ERA. Opponents are batting just .237 off him at Citi Field, compared to .300 on the road.
Pelfrey (pictured), who has gone at least six innings in six of his nine starts this season, is 13th in the NL in ERA, but his strikeout to walk ratio is underwhelming at 39/21 (to compare Aaron Harang of the Reds has a 5.98 ERA and a 48/13 K/BB ratio).
Here are the Phillies' career numbers against the 6-foot-7 righty, a collective .302 average and .369 on base percentage. They have battered him around in the past with eight home runs, including four (with eight RBIs) for Chase Utley.
Ryan Howard is 11-for-25 (.440) with a home run and three RBIs off Pelfrey, while Shane Victorino, Raul Ibanez and Greg Dobbs have also homered off the tall righty.
In 10 starts against Philadelphia, Pelfrey is 4-3 with a 5.43 ERA.
As for Hamels, the 2008 World Series MVP is having a resurgent season after a lackluster 2009. He has gone at least six innings in six of his last seven starts (and the other was a five-inning victory), and hasn't allowed more than three runs in his last four outings. Hamels has 60 strikeouts in his nine starts.
Against the Mets, he is 2-4 with a 4.12 ERA in nine starts, but he has yet to face them this season.
