NEW YORK -- Nationals outfielder Wily Mo Pena didn't start for the second straight game on Tuesday, and manager Manny Acta wants Pena to work on his hitting, which has been below average this season.
Entering Monday's action, Pena is hitting .219 with five RBIs, and he has been vulnerable to breaking balls.
"[Pena] has been working with [hitting coach] Lenny [Harris]," Acta said, "and making sure that he lays off the ones that are off the plate. He is going through a struggle like a lot of the guys here right now."
