"I've been in the situation where things aren't going so well for the previous guy when I come in, being in the long role the last two years, so that wasn't anything new," Ottavino said. "We're a family down there [in the bullpen] and obviously it's been a tough year, but everybody is trying to pick up each other."
Ottavino's greatest escape came in the seventh, when the Dodgers rallied for five runs.
Nick Masset started the inning by serving up a wind-assisted ground-rule double to A.J. Ellis. Masset allowed all four batters he faced to reach before being helped off by a trainer with a left knee injury.
In his first appearance in more than a month since working his way back from an elbow injury, left-hander Boone Logan compounded the mess rather than mop it up.
Logan spent 14 pitches, including a wild one that skipped off the backstop, before his first called strike was greeted with a patronizing cheer from the Coors Field crowd. By then, the inherited runner had already scored on a Hanley Ramirez single and Adrian Gonzalez had reached on a four-pitch walk.
After Matt Kemp's walk loaded the bases, Rockies manager Walt Weiss brought in his third reliever of the inning, Ottavino, without an out having been recorded.
Ottavino proceeded to induce Juan Uribe into a routine 6-4-3 double play before ringing up Ellis on a called third strike.
"We got an 8-2 lead and had the game in hand, but it looked like it was slipping away in that seventh," Weiss said. "Fortunately, we pulled it together and Otto was huge."
In the Dodgers eighth, after Dee Gordon slapped a one-out pinch-hit single and stole second, Ottavino buckled down yet again. With one out, he blew a 97 mph fastball past Yasiel Puig for a swinging strikeout, a personal victory he took pride in considering Puig crushed a homer off him to the deepest part of Coors Field last season.
"He hit a long homer off me the first time I ever faced him," Ottavino said. "Ever since then, I've really made a point to try to get him out as well as I can."
But the most satisfying out of his two-inning outing was the weak ground ball generated off Ramirez's bat to end the eighth with the Rockies clinging to a one-run lead.
"All of it would have meant nothing if I gave up a hit to Hanley at the end [because] Gordon is going to score on anything," said Ottavino, who pumped his fist and slapped his glove after that final out. "Nothing would have mattered if I wouldn't have finished it off."
In the first inning, the Rockies answered two quick runs with a rally of their own off Dan Haren (8-5). Corey Dickerson's ground-rule double plated Josh Rutledge before Wilin Rosario snuck a single past Dodgers second baseman Miguel Rojas to tie the game.
In the third inning, Drew Stubbs followed up another Rosario RBI single with a two-run, opposite-field blast, and the Rockies continued to build on their lead from there.
Dickerson's solo shot to the upper deck of right field made it a 6-2 game in the fifth. An inning later, the Rockies added two more off Charlie Culberson's RBI triple and Charlie Blackmon's RBI single off the glove of Rojas.
"Baseball is a humbling game," said Haren, who was charged with all eight of the Rockies' runs. "Five days ago I couldn't have felt any better. Today, I just wore it out there, basically. If I throw the game I've thrown all year, we win. I just couldn't do it."
Jorge De La Rosa (9-6) secured his third consecutive win by limiting the Dodgers to three hits and two runs over six innings. The fact that the Rockies' three wins over the past 19 games came with De La Rosa on the mound wasn't lost on Weiss.
"It was good timing with Jorgey going out there with the tough stretch we've been in," Weiss said. "We always feel good with him on the mound, and he stepped up and gave us a great performance."
In his first appearance since allowing the game-winning run on Thursday, LaTroy Hawkins logged a 1-2-3 inning for his 15th save of the season.
