Surprise Six: Colby Lewis' perfect day

SURPRISE, Ariz. -- Pitcher Colby Lewis was perfect in four innings against the Chicago White Sox. Here's six things to take away from the Rangers on Saturday.

1. Lewis decided to pitch one more frame than scheduled, but he still didn't allow a hit. He faced the minimum 12 batters in four innings. Lewis struck out five batters, including striking out the side in the second.

2. Craig Gentry left the game in the game with one out in the fifth inning. Manager Ron Washington said it was out of precaution. When Gentry entered the dugout, he said he was fine.

3. Alexi Ogando will pitch in Sunday's B game against the Kansas City Royals. He's scheduled to pitch three innings.

4. Mike Napoli was a late scratch from the lineup. He felt a little soreness in his left groin. The Rangers are calling it mild, but Napoli would've likely played if this was a regular-season game.

5. Yu Darvish threw live batting practice Saturday morning. He's slated to pitch three innings against the Cleveland Indians Tuesday.

6. Ben Lindbergh of Baseball Prospectus takes a look at how Neftali Feliz will transition from a reliever to a starter.
