ST. LOUIS — Jonny Gomes hit a tiebreaking, three-run homer in the sixth inning and the Boston Red Sox rallied to beat the St. Louis Cardinals 4-2 Sunday night, tying the World Series at two games each.

David Ortiz added three hits and also encouraged the Red Sox, shouting at his teammates from second base after a double and later gathering them for a huddle in the dugout.

Inserted into the starting lineup about 75 minutes before gametime because Shane Victorino had a stiff back, Gomes was 0 for 9 in the Series before connecting off reliever Seth Maness.

Felix Doubront won in relief of starter Clay Buchholz. John Lackey made a rare relief appearance to set up for Koji Uehara’s save.

Game 5 is Monday night, with Jon Lester starting for Boston against Adam Wainwright.
