Astros' Luke Gregerson: Fans three in Tuesday's win

Gregerson struck out the side in a perfect eighth inning in Tuesday's 8-4 win over the Athletics.

Gregerson has allowed two runs while striking out 15 over his last 10 innings. An out-of-sync stretch earlier this season prompted manager A.J. Hinch to replace him with Will Harris and Chris Devenski as the main setup and high-leverage relievers, but Gregerson has been slowly earning back the manager's confidence.
