Jorge Posada hasn't caught since returning from the disabled list on June 2, but he's still not totally comfortable as a designated hitter. He says it has been difficult to stay in the game mentally. Posada was hitting just .133 with 1 RBI in 30 at-bats since his return heading into Saturday's action. "It's tough to do; it's not easy," Posada said of being a designated hitter. "It's not a like or a dislike. It's just not like when you play everyday. It's like pinch-hitting four times. You've got to get used to it and learn to be involved and be a part of it."
