The only hit he allowed was a bases-loaded triple by Omar Infante, which helped the Marlins win 6-3 Sunday.
Still, Jimenez was encouraged by his second start since a cut cuticle on his right thumb sent him to the disabled list. He went five innings, battling Marlins ace Josh Johnson on even terms, and the only hit he allowed was by Infante.
"I felt like my old self out there that first four innings," said Jimenez, the All-Star game starter in 2010. "I was throwing my breaking balls for strikes, and I had my velocity."
Jimenez walked the bases loaded with nobody out in the fifth, then retired the next two batters before Infante came through.
"The last inning I ran a little bit out of gas," the right-hander said. "My velocity got a little bad."
Colorado leads the majors in comeback wins, and they nearly pulled off another one, scoring twice in the top of the eighth to tie the game.
"We threw a very bad pitch to Mike Stanton," Rockies manager Jim Tracy said. "It was a breaking ball that didn't do anything. He's going to hit those balls out of the ballpark, it's that simple."
Stanton's second homer this year earned him a curtain call from the crowd of 11,442. Slowed earlier by injuries to both hamstrings, the young slugger has hiked his average to .265.
"Being able to finally play every day and not have these mishaps here and there is good for me, and I'm getting a little more comfortable," he said.
The game matched two pitchers who finished in the top five in NL Cy Young Award voting last year. Jimenez and Johnson both brought their good stuff, and the game remained hitless until the fifth.
"I looked up there, and it was a lot of zeros," Johnson said. "I was like, 'This is what everybody wanted.'"
The game wasn't exactly what Florida All-Star shortstop Hanley Ramirez had in mind. A hitless afternoon left him 2 for his past 27, and manager Edwin Rodriguez said he may give the 2009 NL batting champion a day off Monday.
"I'm trying too hard, chasing bad pitches, and you see the pitches go 100 mph," Ramirez said. "I've just got to calm down and get back on track."
His attitude has drawn criticism in the past, and last year he was briefly benched for a lack of hustle. But new Marlins catcher John Buck praised the way Ramirez has dealt with his slump.
"All I heard about was as far as him not being a leader when stuff goes bad," Buck said. "But I think the best thing that could happen is him starting out bad and being the team player he has been. He's struggling probably the worst on the team, but when I'm making an out, he's the first one patting me on the back.
"Whatever he has been in the past is far from what I've experienced here. And if he gets going, it's going to be something fun."
The Rockies are sputtering at the plate, too, despite leading the NL West. They had six hits against four Florida pitchers and totaled only 13 in the three-game series.
Stanton snapped the tie.
"He's the type of player where, if you make one mistake, he can hurt you," Rockies first baseman Jason Giambi said. "We battled back, but unfortunately one swing of the bat turned the game around."
