HOUSTON -- Astros manager Bo Porter successfully challenged a play in the fourth inning of Monday night's series opener against the Mariners.
Porter contested that a ball hit down the left-field line by Dustin Ackley was foul. The ball was originally ruled fair, and Ackley made it to second base with one out as a result.
The challenge was Porter's 16th, with nine of those overturned. It was Porter's first challenge regarding whether a hit was fair or foul.
