Following an off-day on Friday, the Red Sox will again try to stay alive in Saturday night's Game 6, when they send Curt Schilling to the mound at what figures to be an electric Fenway Park.
The Indians lead the best-of-seven series, 3-2, meaning they still have two more chances to get to the World Series.
The Red Sox, meanwhile, knew their margin was at zero, and they played like it.
In particular, Beckett pitched like it while improving to 3-0 with a 1.17 ERA this postseason. Over eight innings, the Red Sox ace allowed just one run on five hits while fanning a season-high 11 batters.
"I felt good," said Beckett. "Like we always say, it's easy when you've got everything going. Once again, I had great defense and I held them off just long enough for us to put up some runs. It was a team effort. We know what we have to do now: We have to win."
That's all Beckett has done this October. And at the age of 27, he is quickly establishing himself as a legendary performer this time of year, pushing his career postseason record to 5-2 with a 1.78 ERA.
"He's the man. He's the man in the playoffs," said Red Sox left fielder Manny Ramirez, who has transformed into a media darling in this series while remaining a hitting machine. "That's why he's our No. 1 starter. We've got a lot of confidence in him."
The Red Sox are still alive in their quest to try to become the 11th team in the history of postseason play to rally back from a 3-1 deficit.
"We just have to keep grinding it out," said second baseman Dustin Pedroia. "Our backs are still against the wall. We just have to play it pitch by pitch and go from there."
While Beckett was front and center in this win, the offense also regained its groove. Pedroia went 2-for-4 from the leadoff spot. Kevin Youkilis homered and tripled while driving in three runs. David Ortiz added a hit, two walks and two RBIs, while Ramirez went 2-for-4 and narrowly missed hitting a home run.
The Red Sox didn't trail once.
"I think getting ahead was a huge factor for us in this game," said Youkilis. "We know when Josh Beckett is on the mound, we know maybe that one run could be all we need in a game."
Clinging to a 2-1 lead after five, the Red Sox finally got the insurance they seemed to be on the cusp of all night against Indians ace C.C. Sabathia.
Pedroia led off the sixth with a double to right-center and Youkilis brought him home with a triple that went off the glove of a diving Grady Sizemore. Indians manager Eric Wedge then lifted Sabathia in favor of Rafael Betancourt, and Ortiz lofted a sacrifice fly to left to make it 4-1.
"When we have the little guys getting on base, it's a totally different situation," said Ortiz. "We had the little guys on base and the middle of the lineup comes up to hit."
And hit they did.
The Sox broke it open with three in the eighth, sending eight batters to the plate.
"We really did a good job getting runners on base early, but we didn't do a whole lot with it," said Red Sox manager Terry Francona. "But we stayed at it and stayed at it and finally cashed in."
Looking to play with a lead, the Red Sox got one quick as Youkilis belted a solo homer to left with one out in the first. With two outs, Ramirez hit a double to left-center. Mike Lowell followed with a single to right, but Ramirez was thrown out at the plate by Indians right fielder Franklin Gutierrez.
The Indians bounced right back in the bottom of the first, as Sizemore led off with a bloop double down the line in left. Asdrubal Cabrera followed with a single to right, setting up runners at the corners with nobody out. Travis Hafner then hit into a 6-3 double play, but Sizemore crossed home with the tying run.
"I thought I executed my pitches pretty well in the first inning," said Beckett. "Just unfortunately you give up a bloop hit to a guy that's ... good hitters find ways to get hits, and Grady is definitely one of those."
After that, Beckett basically pulled the plug on the Indians, throwing his mid-to-upper-90s heat on the corners and dropping in curveballs at will.
"He was unbelievable," said Ortiz. "We have a lot of confidence in Josh, and I'm pretty sure the rest of our pitching staff is going to put it together just like he did."
Back came the Red Sox in the third, with the top of the order again making things happen. Pedroia led off with a single to right. After Youkilis hit into a double play, Ortiz drew a walk. Up stepped Ramirez, who lofted a drive to right-center that landed on the top of the yellow line that rests above the wall before bouncing back into play.
Ortiz came home and Ramirez, who thought it was a homer off the bat, settled for an RBI single that made it 2-1 Red Sox. Ramirez and Francona both argued vehemently that it was a home run, but the umpiring crew, after huddling for a bit, stuck with the original call. According to the Jacobs Field ground rules, a ball must be hit over the yellow line to be a home run.
"I thought it was out [of the park], but what can I say," Ramirez said.
As it turns out, it didn't much matter.
The bottom of the fifth began with an interesting wrinkle. Kenny Lofton worked Beckett to a 3-0 count and then thought he had walked on the next pitch. But it was ruled a strike. Perhaps Beckett was upset that Lofton presumed he had walked. Because once Lofton popped the next pitch into shallow left, Beckett appeared to shout something in his direction. Lofton was not amused, and after turning the corner at first base, he went towards Beckett. Both benches emptied briefly but nothing came of it.
Beckett and Lofton had a similar war of words in 2005 during a Marlins-Phillies game.
"It was a lot of stuff," said Beckett. "It kind of goes back before today. Those things have a way of working themselves out though."
Casey Blake and Sizemore then produced consecutive singles, but Beckett blew a 97-mph heater by Cabrera to end that threat.
Though Beckett won't start another game in this series, he all but vowed to be there if his team needs him out of the bullpen in a potential Game 7.
"We'll delve into that later," Beckett said. "Obviously I'm preparing myself for them to ask me that, and as of right now, yeah, I think that would be something I could do."
But all Beckett was thinking about in Game 5 was getting his team another game. That mission was accomplished in dominant fashion.
"Awesome," said Pedroia. "He's been doing it all year long. That's why he's one of the best in the game. He dealt tonight."
And thanks in large part to that, Fenway Park is not yet closed for the season.
