Alfonso Soriano and Miguel Tejada stayed put Monday afternoon, and on paper, Bobby Abreu may look like the only impact player to change teams before the July 31 trade deadline. But it may be right-hander Cory Lidle who makes the biggest contribution among the newest members of the Yankees. It's conceivable Lidle could be the top pickup of all players changing teams over the last few days. The Yankees are one of a number of contenders who are getting little out of their fourth and/or fifth starters. Starters other than Mike Mussina, Randy Johnson and Chien-Ming Wang have gone 2-3 with a 9.26 ERA in nine starts during July, putting a lot of stress on the Yankees' bullpen with a string of short outings. The 34-year-old Lidle, on the other hand, has won his last four starts -- beating Pittsburgh, San Francisco, Atlanta and Arizona. He pitched eight innings in both of his last two wins. Even more noteworthy may be Lidle's tendency to be at his best in August and September. He is 78-69 lifetime with a 4.54 ERA, but 31-16 (3.53 ERA) over the final two months of the season. Pitchers acquired by the Yankees -- from Kenny Rogers to Jeff Weaver -- have struggled in the pressure-packed environment of New York, but Lidle should be fine knowing he's not the staff anchor. He just needs to keep the Yankees' high-powered offense in games and he should get his wins.
