If not for another Very Bad Inning by Joba Chamberlain on Saturday, the Yankees might have swept all seven games of last week’s West Coast road trip, thanks to some awfully good starting pitching. Yesterday was CC Sabathia’s turn: The lefty earned his eighth-straight victory (and twelfth win overall) with seven innings of one-run ball. (Unlike Javier Vazquez the night before, Sabathia also got plenty of run support in the 8–2 win.) The Yankees staff allowed no more than two runs in any of the six wins over Oakland and Seattle — the four runs in the game they lost all came on the grand slam surrendered by Chamberlain — and the Yankees enter the All-Star break winners of eight of nine overall, two games ahead of Tampa Bay with a Major League best 56–32 record.
