W2W4: Phillies-Mets (Saturday)

With the help of Baseball-Reference.com, five things to know about the Phillies-Mets matchup on Saturday at Citi Field.

1: Phillies starter Cole Hamels is 2-9 career against the Mets (worst W-L among active pitchers) and has lost his last five decisions against them. He's 64-38 for his career against all teams other than the Mets.

2: Mets starter Mike Pelfrey is 2-0 with a 2.00 ERA in four starts at Citi Field this season, and 12-3 at home dating back to the start of 2010.

That includes three starts at home against the Phillies last season in which he allowed five runs in 21 1/3 innings pitched.

Pelfrey's ERA in eight home starts against the Phillies: 2.75. In seven road starts against them: 9.38.

3: Struggling Mets left fielder Jason Bay has had his issues in limited time against left-handed pitching this season, hitting .227, with 10 strikeouts in 22 at-bats. Perhaps he'll see the ball better tonight. Both his hits in four at-bats against Hamels are doubles.

4: Dating back to the start of the 2009 season, Carlos Beltran has 14 home runs in 177 at-bats against left-handed pitching (a home run every 12.6 at-bats). In that same span, he has 11 home runs in 518 at-bats against right-handed pitching (one every 47 at-bats).

5: Phillies slugger Ryan Howard has a pair of home runs in four at-bats against Pelfrey this season. Howard entered 2011 with three RBIs in 30 at-bats against Pelfrey, but already has that many this season.
