ST. PETERSBURG, Florida — Pinch hitter Ben Williamson delivered a walk-off single in the 12th inning on Tuesday, and the Tampa Bay Rays staved off elimination with a 4-3 victory over the Milwaukee Brewers in Game 4 of the World Series.

The Brewers, who squandered a lead in the 12th, still hold a 3-1 advantage in the best-of-seven series and need just one more win to close it out. Game 5 is scheduled for Wednesday in St. Petersburg, where Tampa Bay must win to force a Game 6; a Milwaukee victory would end the series. To complete the comeback, the Rays would need three consecutive wins.

"Gritty. Gritty. We're dangerous," Tampa Bay's Nick Martinez said. "We have our backs against the wall. We know what we have to do. We can win four in a row. This team is capable of doing that."

Rookie Cooper Pratt capped a four-hit performance with a home run leading off the top of the 12th, putting Milwaukee ahead 3-2. Tampa Bay then rescued its season with a two-run rally in the bottom of the inning.

Junior Caminero opened the 12th by reaching on a throwing error from third baseman Joey Ortiz, which chased pitcher Antonio Senzatela from the game.

"There's no excuse. Not one at all," Ortiz said. "I should make that play every f—- time."

Shane Drohan (0-1) took over for Senzatela and yielded a single to Liam Hicks, putting runners on the corners. Jonny DeLuca then lined a single up the middle to plate pinch runner Cedric Mullins and tie the game at 3-3.

Chandler Simpson followed with a single to load the bases before Williamson chopped a ball into right field, driving in pinch runner Nick Fortes to end the game.

Drohan, making his first relief appearance since Oct. 15, accepted responsibility afterward. "(It's) definitely hard. I'm human, but I knew what I was walking into. I just didn't get the job done," said Drohan, who was charged with one run on four hits without recording an out.

Williamson had been 1-for-15 in the postseason before delivering the game-winning hit.

"You guys know how the game works, it's momentum, and we just got it right now," DeLuca told Fox Sports. "We're going to do everything we can to keep it going into tomorrow. We love the position we're in. We love being underdogs. We know the fight we have in this clubhouse, coaches, team, everyone. It's a fun position to be in."

Brewers captain Christian Yelich expressed confidence that his team would respond to the loss. "You're supposed to face adversity. You have to battle back from it. That's why you celebrate at the end, because that's what it requires out of you," he said. "I believe in our room and I believe we're prepared to meet that challenge."

Pratt, who also hit an RBI double in the fourth inning, drove a 2-2 sweeper from Ian Seymour (2-0) over the wall in left-center field in the top of the 12th. Seymour was charged with one run on two hits in one inning of work.

Milwaukee's Jackson Chourio collected two hits, raising his total to 10 hits through the first four games of a World Series. The only other player to reach that mark was Babe Ruth in 1928.

David Hamilton atoned for an earlier miscue by homering to lead off the fifth inning, pulling the Brewers even at 2-2.

Simpson contributed an RBI double in the second inning and, with the game still tied 2-2, a leaping catch at the wall in the ninth for the Rays, who at least temporarily prevented the Brewers from clinching their first World Series title.

Tampa Bay opened the scoring in the second, when DeLuca reached on a fielder's choice and hustled home on Simpson's double into the right-field corner.

Milwaukee answered in the fourth, as Sal Frelick singled with two outs and scored on Pratt's double into the left-field corner to even the game at 1-1. The Rays responded in the bottom of the frame, when a throw to first base from third baseman Hamilton sailed off the mark, allowing Caminero to score from second for a 2-1 Tampa Bay lead.

In the fifth, Hamilton sent a 0-2 fastball from Griffin Jax over the wall in right-center field to tie the game at 2-2. The blast chased Jax from the game.
