The Nationals scratched Mark DeRosa, who had been starting in left field, from the lineup today, but DeRosa plans to return tomorrow night after experiencing minor tightness in his left calf.

DeRosa first felt the tightness during the Nationals’ game Tuesday and played through it.

“It’s not a big deal,” DeRosa said. “Nothing I’m concerned about.”

The Nationals are counting on DeRosa as a possibile left field fill-in should Michael Morse begin the season on the disabled list and as part of a first base platoon with Adam LaRoche.

DeRosa has recently recovered from various wrist injuries that limited to a handful of games the past two seasons. With that as the backdrop, DeRosa had no intention of rushing back with his calf injury.

“I figured, why go out there and jeopardize everything?” DeRosa said. “I’ve worked so hard. If anyone is tired of being in the training room, it’s me.”

For today’s game, Xavier Nady moved from right field to left and Brett Carroll played right.
