ST. LOUIS -- With one swing, Jonny Gomes made the World Series a best-of-three.
Gomes' three-run homer off reliever Seth Maness in the sixth inning Sunday night snapped a 1-1 deadlock and lifted the Boston Red Sox to a 4-2 win over the St. Louis Cardinals in Game 4, tying the series at two games apiece.
Gomes, who was hitting .148 in the postseason prior to his blast, was in the lineup only because right fielder Shane Victorino was scratched about 80 minutes prior to the first pitch due to lower back tightness.
Jumping on a 2-2 fastball from Maness, Gomes ripped the ball to left-center and over leaping left fielder Matt Holliday as the ball settled into the Boston bullpen, quieting a Busch Stadium-record crowd of 47,469.
While Maness crouched between the mound and first base line with his head down, Gomes fired his right fist in the air to celebrate the biggest hit of his career.
Felix Doubront pitched 2 2/3 innings out of the Red Sox bullpen to get the win. Koji Uehara worked around Allen Craig's pinch-hit single in the ninth inning for a save, picking off pinch runner Kolten Wong at first for the final out.
Lance Lynn was tagged with the loss. He pitched 5 2/3 innings and allowed three hits and three runs while walking three and fanning five.
Game 5 is Monday night at Busch Stadium, with Jon Lester pitching for Boston and Adam Wainwright working for St. Louis. It will be a rematch of Game 1, won easily by Lester, 8-1. Game 6 and, if necessary, Game 7, would be in Boston on Wednesday and Thursday, respectively.
St. Louis started the scoring in the bottom of the third. Matt Carpenter singled with one out and moved to second when center fielder Jacoby Ellsbury booted the ball for an error. Carlos Beltran grounded a single past diving second baseman Dustin Pedroia for a 1-0 lead.
Boston finally got its offense going in the fifth after Lynn faced the minimum 12 hitters through four innings. David Ortiz led off with a double to right-center. After consecutive walks to Jonny Gomes and Xander Bogaerts filled the bases, Stephen Drew lofted a first-pitch sacrifice fly to left, scoring Ortiz to tie the game. Lynn kept the game even by striking out David Ross and getting pinch hitter Mike Carp to ground out to first.
Red Sox starter Clay Buchholz, pitching with an aching right shoulder, worked the first four innings. He allowed three hits and an unearned run, walking three and striking out two.
Ortiz went 3-for-3 with a walk, raising his series average to .727.
Carpenter collected two of the Cardinals' six hits.
NOTES: Before the game, Major League Baseball recognized Detroit Tigers 3B Miguel Cabrera (American League) and Arizona Diamondbacks 1B Paul Goldschmidt (National League) as winners of the Hank Aaron Award, given to the best hitter in each league. ... Boston and St. Louis combined to use 12 pitchers in Saturday night's Game 3, tying the World Series record for a nine-inning game that was set in 2007 (Boston-Colorado Rockies) and equaled in 2010 (Texas Rangers-San Francisco Giants). ... Game 3 also represented the first postseason contest to end on an error since Bill Buckner's infamous flub in Game 6 of the 1986 World Series gave the New York Mets a win over the Red Sox.
