Texas Rangers right-hander Yu Darvish did just fine without a scouting report on the Colorado Rockies.

He struck out 11 in six innings in a 5-3 victory over the Rockies on Friday night. He allowed three runs and six hits and walked one.

Jason Giambi hit a two-run home run, his first of the spring, off Darvish in the second inning. Both Giambi and Todd Helton hit doubles off Darvish, who will be the Rangers' No. 4 starter.

The Rangers' Josh Hamilton left the game after seven innings with a tight left groin. He's day to day.

The Rockies' Michael Cuddyer left in the sixth after a Darvish fastball hit him on the right hand. He suffered a bruise.

Darvish struck out Carlos Gonzalez and Troy Tulowitzki each three times.

"It didn't seem like I had that many strikeouts," Darvish said through an interpreter. "But just the way me and (catcher) Mike Napoli, the way we worked together tonight, some of the great pitch calling that he made for me, and the way I was able to pitching comfortably, that all led to the 11 strikeouts."

Darvish walked the first batter he faced, Marco Scutaro, but ended the first inning with strikeouts to Dexter Fowler, Gonzalez and Tulowitzki.

In the second inning, Helton led off with a double, and Giambi followed with a two-run home run.

"I threw a strike, and he hit a home run, which I deserve to get hit in that situation," said Darvish, whose ERA is 3.60. "Giving up a home run to a hitter like Jason Giambi, I'm kind of honored by that."

Darvish threw 98 pitches and got in trouble in the sixth inning. He gave up a leadoff single to Fowler, and after a stolen base, wild pitch and two outs, he allowed an RBI single to Helton, a double to Giambi and hit Cuddyer. A flyout ended the inning.

Darvish said he didn't get tired.

Rangers manager Ron Washington said Darvish didn't seem fatigued, as he continued to show good velocity.

"He had a good four-seam fastball working. He was moving it around, threw some good sinkers, went through some pretty good hitters, especially those left-handers," Washington said. "Each time he's taken the ball, he's gotten better."

Darvish will make his final start before the regular season Wednesday in Frisco, Calif., against the Rangers' Double-A team.

Rockies starter Jhoulys Chacin allowed five runs and nine hits in 61/3 innings. He struck out three and walked one.
