Extra inning doesn't tarnish Lewis' perfect day

Rangers righty needs just 36 pitches to get through four frames

GLENDALE, Ariz. -- Colby Lewis had no trouble talking his way into an extra inning Saturday against the White Sox. Going for the perfect game, though, was probably not a realistic option.

The Rangers' right-hander needed just 36 pitches to toss four perfect innings in Texas' 3-2 loss, though he was only scheduled to throw three.

"I was at, like, 28 pitches or something and was only scheduled to go three, but they asked me if I wanted to go in the bullpen or out in the game, and I'd rather have them out in the game -- there's a little more adrenaline when you're in the game," Lewis said. "So I threw another inning and it worked out good."

Lewis struck out five batters, including all three -- Chicago's Paul Konerko, Adam Dunn and A.J. Pierzynski -- in the second.

"He was hitting his spots with his fastball, dropping a couple breaking balls with two strikes," manager Ron Washington said. "Moved it around, kept it down. Didn't elevate it much today at all."

It was a pleasant bounce-back outing for Lewis, who surrendered two earned runs in as many innings in his Spring Training debut against the Royals on Sunday, walking one and surrendering a home run. He was 14-10 with a 4.40 ERA last year, his second in a row logging at least 200 innings.

Lewis said he knew he was in line for a perfect game Saturday -- at a pace to do it in a remarkable 81 pitches, no less -- but also knew it wasn't an option at this point in the year.

"It would have been kind of cool if it was midseason form to see how long you can go," Lewis said. "But it was a good time to go out there and pound the strike zone and get outs and get quick outs."

C. Jackson not concussed after fielding mishap

GLENDALE, Ariz. -- Conor Jackson had a large gash above his left eye Saturday morning in the Rangers' clubhouse -- to go along with five stitches -- but he said there were no lingering symptoms of a headache or concussion, and he hopes to get back into game action shortly.

Jackson, playing right field in the sixth inning of Friday's game, misplayed a fly ball and it struck him above his left eye. He was removed from the game, but X-rays Friday revealed that he did not suffer any structural damage, and Jackson said that he did not suffer a concussion on the play.

"It was kind of a short ball to the line, I was running in and kind of took my eye off it for a split second to see where the second baseman was, looked back up and caught a little bit of sun and caught a little bit of glare," Jackson said. "And that was all she wrote."

Assistant general manager Thad Levine said Jackson will not play Saturday, and may engage in some "mild exercise" but nothing more at this point.

"It's not super swollen, it's not blurry vision, I'm not concussed," Jackson said. "I'm not going to sit here and take days off until it's 100 percent. I don't have that luxury. The only problem is it's my lead hitting eye -- it's the eye that's facing the pitcher, so that's the only thing I can see being an issue."

The 29-year-old outfielder signed a Minor League contract with the Rangers this year after seven seasons in the big leagues, primarily with the D-backs. He hit .244 with five homers and 43 RBIs in 114 games last year with Oakland and Boston.

"The only way it can be a setback is if we have problems with concussion problems," manager Ron Washington said. "If we don't have problems with that, as soon as he feels like he can see well enough, he's back on the field."

Napoli scratched with minor groin issue

GLENDALE, Ariz. -- Catcher Mike Napoli was a late scratch from Texas' traveling lineup for its Saturday game against the White Sox due to a nagging left groin issue.

The team is holding him back purely as a precautionary measure, and Napoli said it was just a little sore and he didn't feel the need to push anything.

"There's no concern," manager Ron Washington said. "He's got some little nagging things, and we just want to make sure it doesn't turn into anything more. He's getting some at-bats -- it's not like he's falling behind. We just want to make sure that little nagging things don't turn into anything more than what they are."

Washington said Napoli, who came into camp with a high left ankle sprain, was scheduled to have the day off on Sunday but is now likely to play against the Indians.

Gentry exits but says hamstring will be 'fine'

GLENDALE, Ariz. -- Rangers right fielder Craig Gentry left Saturday's game in the bottom of the fifth inning with tightness in his left hamstring.

Gentry said he was somewhat surprised to see Kyle Hudson trotting out of the third-base dugout to replace him in right field and was able to jog back into the dugout with relative ease.

"They saw me out there stretching and just decided to play it safe and get me out of there. ... It'll be fine," Gentry said. "I should be in there tomorrow."

Gentry said he may have tightened up a little bit in his prior at-bat -- a groundout to third base -- but didn't expect it to hold him back at all in the coming days.

"He was out there grabbing his hamstring, but when he came in, he said he was fine," manager Ron Washington said. "I had already made the move and I didn't want to take any chances."

Worth noting

• Infielder Brad Hawpe, who has been battling tightness in his right hamstring, will run on Saturday, and if that goes well, he will be in the lineup for the Rangers' "B" game on Sunday against the Royals.

• Right-hander Alexi Ogando will throw in Texas' "B" game on Sunday. "Just so he can be comfortable and get his innings in," Washington said. "We want to stretch him out. ... This way, we can look at some other guys and Ogando can get his work back there. He's still gonna face big league hitters."
