The Texas Rangers are starting to wonder if Yu Darvish can strike out 300 batters this season.

No pitcher has struck out that many batters since Randy Johnson and Curt Schilling did for the Arizona Diamondbacks in 2001.

So far, Darvish has 49 strikeouts in less than 33 innings.

"He can finesse you, and he can overpower you," Rangers manager Ron Washington said. "He knows what he has when he comes out of the bullpen, and he knows what he can use. He's comfortable out there."
