It took more than four months, but the Yankees seem to have finally caught a break. They should have been celebrating a big 5-1 win over Justin Verlander and the Tigers, but instead there was the all-too-familiar hush in the home clubhouse as they wondered how much time Mark Teixeira would miss after cutting his left pinkie finger while sliding into home in the eighth. Joe Girardi ruled Teixeira out for Thursday’s series finale, but the first baseman needed only three stitches to close the small wound and X-rays were negative, a rare bit of good news for the injury-ravaged club. “You play hard, that’s what happens,” said Teixeira, who has dealt with myriad injuries all season. “I’m just happy about the win. That was a great team win. Hopefully I won’t be out long and I’ll see how it feels tomorrow.” For a team that has been starved for power through most of the year, another major Teixeira injury would be a blow to the lineup. But given Carlos Beltran’s red-hot bat over the past five weeks, the solid play of Chase Headley since his July 22 trade and Brian McCann’s sudden power surge, the Yankees’ lineup is starting to look the way they envisioned it would this season. “It all starts with starting pitching,” said Headley, praising the efforts of Brandon McCarthy, Hiroki Kuroda and Chris Capuano the past three nights against the Tigers’ Cy Young trio. “When those guys go out there and give us a chance to win each and every night, I feel like this lineup has the capability to put some runs on the board.” They’ve had the capability all season. Now they’re actually putting that talent to work.
