Dallas Keuchel outpitched college roommate Drew Smyly, and the Houston Astros edged Detroit 6-2 on Thursday to snap the Tigers' eight-game winning streak.
Houston also ended its own five-game losing skid. Keuchel (3-2) allowed two runs and six hits in 7 2-3 innings.
Keuchel and Smyly were both on the Arkansas team that reached the College World Series in 2009. The two left-handers were both sharp early Thursday, but Houston broke through with three runs in the fifth off Smyly (2-2) to take the lead.
Houston's George Springer, a first-round draft pick in 2011, hit his first major league homer. Carlos Corporan and Matt Dominguez also went deep for the Astros.
Victor Martinez homered for the Tigers.
