Clay Buchholz has never pitched well against the Yankees and over the last two seasons, it has taken him several weeks to get into any sort of rhythm on the mound. But the Red Sox righthander felt confident when he took the mound at Yankee Stadium Wednesday night, even in winter-like conditions. Buchholz had pitched extraordinarily well in spring training and knew he was facing a Yankees lineup missing Curtis Granderson, Derek Jeter, Mark Teixeira, and Alex Rodriguez. If ever there was a chance to put two bothersome issues to rest, this night was it. Buchholz made good on the opportunity, allowing one run over seven innings as the new-look Sox beat the Yankees, 7-4. The Red Sox are 2-0 for the first time since 1999, when they started with five consecutive victories under Jimy Williams. The Sox went to the American League Championship Series that season. For now the John Farrell-led Sox would settle for a sweep of the Yankees. Ryan Dempster will face Andy Pettitte Thursday night. The Sox have scored 15 runs on 26 hits in their first two games. They scored 18 runs in the eight-game losing streak that ended last season. “It’s two games of the season. But, hey, it’s a positive start for us,” said Shane Victorino, who had two hits and drove in a run. “It’s always good to start like that.” Buchholz was 2-5 with a 7.19 earned run average in nine career starts against the Yankees. But this time he scattered six hits, walked two, and struck out four. “First start of year, get it out of the way. Especially here,” Buchholz said. “Pitching against this team; it’s never an easy task coming in here and throwing to these guys.”
