Merrill Kelly finished what he had been chasing for years on Friday night at Coors Field, throwing the first nine-inning complete game of his major-league career. The 37-year-old right-hander worked into the ninth, permitted just four hits and no walks, and struck out the final batter to seal the victory on exactly 100 pitches. What might have been a routine managerial call instead became a matter of judgment and trust: Diamondbacks manager Torey Lovullo opted to let Kelly try to complete the game after a lengthy conversation between the two on the dugout steps.

Lovullo’s decision came with recent context: just five days earlier another Arizona starter, Eduardo Rodriguez, had been removed two outs shy of a complete game. That prior situation made the call with Kelly more scrutinized by observers and by the dugout itself. Kelly entered the ninth after a four-pitch eighth inning and after the manager and starter had talked at length on the bench. Kelly did have to work a bit in the final frame — he allowed a one-out double — but Lovullo never sent the bullpen to the mound, and Kelly closed it out with his fourth strikeout of the night.
Kelly’s performance provided some immediate tangible rewards. The outing lowered his earned-run average to 5.91 and represented a follow-up to a seven-inning appearance against the Mets his previous time out. More importantly for Kelly and the club, it was a complete-game achievement that has become increasingly rare in modern baseball. Kelly’s ability to maintain command without issuing a walk and to still generate swing-and-miss with his secondary pitches were central to his extended stay on the mound.
Asked after the game what led him to allow Kelly to finish, Lovullo pointed to the unique playing conditions at Coors Field. The high elevation has been associated with a greater incidence of soft-tissue injuries, the manager said, and that made him especially attentive as Kelly’s pitch count climbed. "I get a little uptight in this ballpark," Lovullo admitted. "We've had a lot of injuries with soft tissue, it's known. I told him I was gonna start to get a little edgy around pitch 95."
That edginess, however, had to be balanced against Kelly’s insistence that he had more left in the tank. According to Lovullo, Kelly asked for a window of seven to 10 additional pitches. "He was battling for seven to ten more pitches and I said, 'We'll see. But I'm not gonna leave you out there just for the simple idea of throwing a complete game. You're way too important to me in this organization and your next start is gonna be equally as important as this one,'" the manager said. The two reached an understanding: Kelly wanted a chance to finish, Lovullo wanted assurances, and both sides agreed to proceed.
Lovullo described the dugout atmosphere as the ninth inning stretched on: teammates were celebrating each out, but he and the coaching staff were becoming increasingly wary. He acknowledged feeling stressed as the inning progressed. "I was getting stressed out, believe it or not. Everybody in the dugout was celebrating Merrill with every out that he was getting. But with each pitch that he was throwing, I was getting more and more anxious," he said. Pitching coach Brian Kaplan leaned toward a more conservative approach, wanting to keep Kelly short; Lovullo countered that Kelly had thrown only four pitches in the eighth and therefore deserved an honest chance to finish the job. "We gotta give him an opportunity to throw a complete game. ... He deserved it. He definitely deserved that opportunity," Lovullo said.
The result was a milestone for both Kelly and the franchise. Kelly became the first Diamondbacks pitcher to complete a nine-inning game since Brandon Pfaadt's nine-inning outing in September 2025, though Pfaadt's outing did not register as a complete game because it extended into extra innings. The last D-backs pitcher credited with an official complete game had been Zac Gallen, whose nine-inning shutout came on Sept. 8, 2023. Lovullo praised Kelly's stuff and preparation after the game, noting that the right-hander still "had gas in the tank" and that his secondary offerings generated a lot of swing-and-miss. "This is what you work hard for in the offseason. This is what you work hard for as you're prepping for moments like this, so you can go out there and finish it and throw a CG. It doesn't happen a lot in baseball anymore, but he did a great job today," Lovullo said.
The decision to let a veteran take one more inning at Coors Field was a calculated gamble rooted in immediate indications of effectiveness and a negotiated agreement between player and manager. Kelly fulfilled the terms by retiring the final batter and protecting his arm through a 100-pitch complete-game effort. The manager’s explanation underscored the balance between safeguarding health and honoring a pitcher’s request to finish a game — a balance that on this night in Denver paid off with a rare and personal milestone for the veteran right-hander.
