At a time the game could have slipped away from him in the fourth inning, Conley collected two critical strikeouts to escape a bases-loaded, one-out jam. Already trailing by a run, the lefty fanned Phillies pitcher Aaron Nola on four pitches, setting up a pivotal showdown with leadoff batter Cesar Hernandez.
The eight-pitch encounter went Conley's way, as Hernandez swung through an 86-mph changeup with the count 1-2.
Hernandez fouled off four straight two-strike pitches before taking a 95-mph fastball for a ball. The next pitch was a well-executed changeup for strike three, stranding three.
"That was big for me," Conley said. "I'd been kind of fighting myself all day, knowing I didn't really have my good stuff, and it was going to be a battle all day."
Conley topped 80 pitches in the fourth inning, and he could have been on his way to a third straight start of not going more than five innings. But he retired the final eight he faced and posted his first big league quality start, scattering three hits with four walks (one intentional) and five strikeouts.
"Six innings: When we can get that, especially from a rookie, that's huge for us," manager Dan Jennings said. "Our bullpen has been taxed of late. For him to do that was big."
A second-round Draft pick of the Marlins in 2011, the organization is striving to see if Conley has a chance to factor into its rotation plans in '16. Even if he doesn't win one of five Opening Day spots, he could be an option either during the season, or perhaps be used in relief.
Conley has now appeared in eight big league games, with four starts. It's been a struggle to get deeper into games, as in his last outing -- a no-decision against the Brewers -- he was lifted after 3 2/3 innings.
"I think today started off pretty rough, but I was able to find some rhythm there at the end," he said. "I made the best of my pitches towards the end there."
