Shane Victorino played for enough winning teams in Philadelphia to understand there are moments within a six-month season that separate the contenders from the also-rans. This was another of those moments. After being muted for eight innings yesterday and facing an All-Star closer, the Red Sox struck for four runs to pull out an improbable 6-5 victory, their second comeback in as many days against an Indians bullpen that hadn’t been credited with a loss all season. “To me, games like this are going to be penciled in, where you say, ‘These guys haven’t lost, and we were able to come back against them,’ ” said Victorino, the injured right fielder, after Jacoby Ellsbury’s bases-loaded, two-out double scored Jonny Gomes and Stephen Drew for the walkoff win. “But this team all year has shown that resiliency. ‘We’re down five, OK, we’ll come right back at you. Don’t count us out.’ That’s what winning teams do, and that’s what I see here.” It was what Victorino saw 11 nights ago when, down to their final strike, the Red Sox got a three-run double from slumping Will Middlebrooks in a come-from-behind 4-3 win over the Rays. He witnessed it again Saturday, when they scored four eighth-inning runs in a 7-4 comeback against the Indians. And it happened again yesterday. The Red Sox notched three hits and worked three walks, including an impressive seven-pitch walk by rookie Jose Iglesias, and took full advantage of a shoulder injury to Indians closer Chris Perez, who left in the middle of Ellsbury’s at-bat. “We’ve seen it many times over,” manager John Farrell said. “This team loves to compete. Until that 27th out is recorded, this team doesn’t roll over by any means.”
