Yu Darvish likes stuff halfway through

ARLINGTON, Texas -- Nearly halfway through his first big-league season, Rangers right-hander Yu Darvish said he's been able to use his full arsenal of pitches and that he's mostly pleased with his progress as he goes for his 10th win in 15 starts tonight against the Detroit Tigers.

"It’s hard to say what a 10 is," Darvish said when asked to rank on a scale from one to 10 how he's adjusted to the mental and physical demand of the season. "But obviously, compared to times when I wasn’t pitching well, it’s come a long a way and I'm feeling much more in sync."

Darvish (9-4, 3.45 ERA) will look to match Matt Harrison for the team lead in wins against the Tigers, a club he beat on the road in his third start. In that game, Darvish worked around two hits and five walks through 6 1/3 innings, allowing just one run.

He said he's not concerned with reaching double-digit victories before the All-Star break. Darvish said he threw two bullpen sessions instead of one since his last start, a strong eight-inning victory at San Diego last Wednesday, but he said it was only to get in extra work.

"Double-digit (wins) or not, to me it is no meaning at all," Darvish said. "Each win is a win. I’m a rookie over here, but it’s not like I’m a true rookie; a rookie in Japan just starting my career. I take one game at a time. I don’t think I’m at a level where I could be happy or satisfied with double digit wins."
