With the designated hitter out of play, Texas Rangers’ Lance Berkman is comfortable with being on call as a pinch-hitter for this week’s first three games. “It’s a good break when you’ve got some aches and pains,” said Berkman, who had two surgeries on the right knee last year while with St. Louis. “I’ll be ready, but this will help.” Mitch Moreland started in the makeup game against the Cubs at Wrigley Field, and Washington expects to start him in both games at Milwaukee. In his first full season as a DH, Berkman said he is gradually adjusting to the unique rhythms of the position. He stays busy during games swinging a bat and taking a spin on an exercise bicycle. He leads designated hitters in average at .303 and on-base percentage at .441 and ranks second in slugging percentage at .449. Travis Hafner of the Yankees leads at .582.
