Suddenly, the Yankees — old, feeble and scandal-ridden — have won four straight games and have played themselves back to the cusp of the periphery of the margins of the wild-card race. They’re just a half-game behind the Royals and 2½ games behind the Orioles, two of four teams they need to pass in this longshot quest. It isn’t time to fit anyone for a World Series ring quite yet, but if this offensive surge continues, there may be remote cause to show up at the Stadium in September other than a voyeuristic peek at Exhibit A-Rod.
