Manager Ron Washington made the decision and inserted Yorvit Torrealba into the lineup Sunday to catch Matt Harrison. Washington said Darvish hasn't said anything about wanting a particular catcher and has communicated well with both backstops.
"I'm excited and it's going to be a special day for him," Napoli said. "I don't know how he feels about it, but I imagine he'll be excited. But he's pitched a lot before. If I need to calm him down or settle him down, I will. But I don't see it going that way."
Napoli said he'll go over the scouting report with Darvish hours before Monday's game, as usual. Napoli caught several of Darvish's games in spring and said they talked before and after the outing and in between innings.
"I want to pick his brain as much as I can," Napoli said. "I'll be doing that all year. I have to learn everything I can and help him any way I can. He's going to be fine. I'm looking forward to it."
* Washington won't be afraid to use closer Joe Nathan for a third straight day if needed. It will depend on the workload and how Nathan feels. Nathan said he expects to pitch on three straight days if needed.
"I'd be upset if they didn't expect that," Nathan said. "I know sometimes my body will say, 'Hey, I need a day.' But we're just three days in. I feel good right now. If I feel good, I can pitch if they need me."
* Alexi Ogando threw just seven pitches in his outing on Saturday after pitching an inning on Friday. If he feels OK, he could be used again as well.
* David Murphy focused this spring on defense. But in the first two games, Murphy has struggled in that department. He lost a ball in the sun on Opening Day and made a wide throw toward home on Saturday that allowed a runner to advance to second. That didn't end up costing the Rangers, but Murphy wanted to fare better.
"I was just excited and pulled that throw," Murphy said. "I lost one in the sun. I don't know if I need to look at my angle or what, but I don't want that to happen. I want to keep improving."
At the plate, Murphy has had early success. He's 3-for-6 with two doubles in two games.
