If that's the case, there could not have been a better situation for Breslow to have come into than the eighth inning Wednesday night.
With the D-backs up, 4-3, the Nationals had put runners at first and second with no one out against Brad Ziegler when Gibson decided to go to Breslow.
"It's a tough situation," Breslow said. "The most important thing in that situation is just take it one pitch at a time, try to get a ground ball, maybe get a double play, and then just worry about one guy on third with two outs, and not kind of get an overwhelmed feeling like you have to get three outs before you give up something. I felt like I executed some pretty good pitches."
Breslow got Adam LaRoche to fly out to right field, then struck out Jesus Flores and Danny Espinosa to end the frame.
Breslow has pitched well for the D-backs this year, compiling a 2.19 ERA in 11 games. As for stranding runners, he has now allowed just two of eight to score this year.
"I think he's getting arm strength and getting locked in with his mechanics, and being more consistent with where he's trying to throw the ball," Gibson said.
Throughout his career, the left-hander has been equally adept at getting left-handed and right-handed hitters out. Entering Thursday's series finale in Washington, he'd held righties to a .222 batting average while lefties have hit just .133.
