Game of the day: Philadelphia at New York Mets, 7:10 p.m. The National League East foes have gone in opposite directions since the peak of their recent rivalry in 2007, but it’s still fun to watch when they get together. The Mets have lost five of their last six games, and they need a strong start from right-hander Mike Pelfrey (3-4) on Saturday. The former first-round draft pick has a 5.25 ERA in 15 career starts against the Phillies, and hasn’t made it past the fifth inning in two rough starts against Philadelphia this year. Phillies left-hander Cole Hamels (6-2) hasn’t pitched particularly well against the Mets, compiling a 2-9 record in 14 career starts.

Other game to watch:

New York Yankees at Seattle, 10:10 p.m. The Mariners won eight of their last 10 games entering their series opener against the Yankees on Friday night, and they send reigning Cy Young Award winner Felix Hernandez (5-4) to the mound Saturday. Hernandez is 5-3 with a 2.73 ERA in eight career starts against New York, and he has allowed two earned runs or fewer in seven of his last eight starts. Right-hander Ivan Nova will start for the Yankees in what will be his first career appearance against Seattle. The Yankees have won four of Nova’s last five starts.
