Daniel Kilgore reports on why Washington Nationals fans should keep their eye on Daniel Rosenbaum.

The more Menhart comes to know Rosenbaum, the more things he comes to like. His fastball, though it sits in the 88-92 range, is “sneaky-quick,” Menhart said. “He’s got that. He induces a lot of ugly swings from a lot of very good hitters. He’s actually got really strong legs. By having those strong legs, he’s able to hide the ball. He’s very deceptive. He’s got a nice, short arm action, and the ball kind of jumps up on you. Hitters don’t pick it up very well. And he’s not afraid to throw in.”

His minor league record is here. I like that he doesn’t walk batters.
