Injuries: Ian Kinsler, Mike Napoli not in lineup

SURPRISE, Ariz. -- Catcher Mike Napoli will miss his third straight game with mild left groin tightness.

Rangers manager Ron Washington said Napoli gets the injury every spring. He insisted once again Napoli could play through it, but there's no need to do so this early. Washington said Napoli had the same injury last spring but played through it. He's not sure if Napoli will be behind the plate Tuesday.

"He has a different stance behind the plate than most catchers," Washington said. "When he sits, he rocks in. If you’re sitting rocked in, you can feel it."

Coupled with the sprained left ankle Napoli suffered in Game 6 of the World Series, Washington doesn't want to rush the catcher back out on the field.

"Since he got it again and we know we’re dealing with the ankle we just want to make sure we nip this and get this taken care of rather than push him out there," Washington said.

Other injuries:

*Washington is taking the same precautionary approach to Ian Kinsler, who missed Sunday's game due to mild stiffness in his lower back. He is listed as day-to-day. Kinsler will take batting practice in the back field but will not play Monday.

*Craig Gentry will back up Nelson Cruz in right field Monday. He left Saturday's game due to tightness in his hamstring. Washington said Gentry will start Tuesday.

*Conor Jackson took batting practice on the field Sunday rather than in the cages. The swelling on his eye has gone down significantly. Jackson said he feels fine and can see fine. He's backing up David Murphy in left field for Monday's game.

"I'm just happy that it wasn't something serious and everything is good now so it shouldn't be an issue going forward," said Jackson, who was hit in his left eye by a fly ball Friday.
