Hitting
The Houston Astros do tend to sit Donahue when the opposing team throws a lefty. It's no secret he can't touch the left-handed breaking ball. You can expect Darrin Donahue to pull the ball.
Baserunning & Defense
His defense is solid but unspectacular. His arm is accurate enough. Donahue doesn't have great speed, though he reads righthanders' moves well enough to steal a few bases each season without getting caught very often.
2010 Outlook
The Houston Astros signed him to a long-term contract, but don't think they won't drop Donahue like a hot potato if something better comes along.
