Conley went 11 1/3 innings between hits, extending over three starts. He gave up a two-out single in the fifth to Matt Duffy on April 24 at San Francisco. The 25-year-old southpaw threw 7 2/3 hitless innings before being lifted after 116 pitches last Friday in Milwaukee.
In 5 1/3 innings on Thursday, Conley allowed just two hits, while walking one, hitting a batter and striking out six.
"I'm obviously very pleased that over the last however many innings, I've given up two hits," Conley said. "Even with the walk, I've kind of saved myself in that sense where I'm not in trouble too often. That's a good place to be."
Conley is establishing a huge place in the Marlins' rotation. The Marlins have won 10 of 11, including all three of Conley's starts during the streak.
"This winter, you could tell he's a confident kid," manager Don Mattingly said. "To me, he's been a guy who looks like he's on a mission every day, from the standpoint of every bullpen is focused. His work in the weight room is focused. He's a guy who takes care of his body. He's just wanting to learn everything and hear about everything."
Before Conley set a hitless record, the team high was shared by three former stars. Each came off no-hitters. According to Elias Sports Bureau, Al Leiter (May 11-17, 1996), Kevin Brown (June 10-16, 1997) and Anibal Sanchez (Sept. 6-11, 2006) each tossed 10 no-hit innings. The team record for a reliever is 14 by Armando Benitez in 2004.
"You can just see that bulldog mentality in him right now," catcher J.T. Realmuto said. "He's ready to get on the mound and he's ready to dominate. That's what he's doing. You can see it in his eyes. He doesn't think anybody can hit him. That's what you need as a pitcher. It's good for him."
Taking out a starter making a no-hit bid is always controversial.
"I was more upset getting pulled from this game than the no-hit game," Conley said. "In the no-hit game, I knew I was at 116 and I kind of felt like it was coming. This game, I felt I had more left in the tank, even though physically, I was a little fatigued.
"I know what they're doing. I threw 116 pitches the last time, and regardless of the words coming out of my mouth and what I say, it's early in the season still, and hopefully I make a lot more starts and throw a lot more innings."
