Coors Field, on an unseasonably hot and dry September night, was like a volcano ready to erupt.

And did it ever.

With a first-pitch temperature of 95 degrees — the hottest ever for a Rockies home game in September — the Rockies and Brewers combined for six home runs in Colorado’s thrilling 10-7, 10-inning victory. Colorado’s four homers were its most in a game this season.

The Rockies won it on Randal Grichuk’s walk-off, three-run homer off of lefty Taylor Rogers. Grichuk’s second homer of the night traveled 457 feet. He became the first player in Rockies franchise history to hit a game-tying home run in the eighth inning or later and then also hit a walk-off home run in the same game. He’s the first big-leaguer to do it since Baltimore’s Trey Mancini on June 7, 2017.

“This one is probably up there, in the top (moments),” Grichuk said. “To hit a game-tying homer in the eighth and then the winning homer. It’s pretty special.”

Grichuk knew he got all of the game-winner.

“That’s the only ball I’ve ever hit where I looked at our dugout and showed some emotion and didn’t just sprint out of the box,” he said.

But the biggest no-doubter of the night came off the bat of the Brewers’ Christian Yelich, who launched the longest home run by a left-handed hitter in Coors Field history.

More on that in a moment.

The Rockies, who trailed most of the night, tied the game, 6-6, with a five-run eighth inning, highlighted by a two-run homer by Yonathan Daza (fresh off the injured list) and a solo shot by Grichuk. Daza launched his solo homer to dead center off of Luis Perdomo. Grichuk’s came off of Peter Strzelecki.

Daza hit his second home run of the season and the fourth of his career. Three of those homers have come against the Brewers.

Asked if he knew his homer was gone, Daza quipped: “No chance. I have no power. … I was happy it went out. I have never hit a ball dead-center in my life. That feels good.”

Now, back to Yelich. After what he did, he should look into a meaty endorsement deal.

The Brewers’ leadoff hitter rocketed the fourth pitch of the ballgame 499 feet and into the third deck in right-center field. The ball landed not far below the Smashburger sign.

The homer, served up by Colorado right-hander Chad Kuhl, was smashed, indeed. Yelich’s homer fell just 5 feet short of the longest overall — a 504-foot blast by Giancarlo Stanton, then with the Marlins on Aug. 6. 2016. The previous record for lefty homer at Coors came on May 30 of this year by the Marlins Jesus Sanchez off of right-hander Ryan Feltner.

And get this: In 100 career at-bats (117 plate appearances) entering Tuesday’s game, Yelich had never hit a home run at Coors Field.

For Kuhl, Feltner, right-hander Jose Urena, and lefty Austin Gomber, tryouts for the Rockies’ 2023 starting rotation have become central to the club’s final stretch of a last-place season.

Kuhl’s latest audition, obviously, did not go well. After serving up the historic homer to Yelich, he walked Willy Adames, setting the table for Hunter Renfroe’s two-run homer and a 3-0 Milwaukee lead.

By the time Kuhl’s 4 1/3-inning performance was done, he gave up five runs on six hits, issuing two walks and striking out five.  After 23 starts, he owns a 5.38 ERA.

“I just felt like the first inning I left two pitches right over the middle and from there on out I felt like I was much more aggressive,” Kuhl said. “I felt like I was out of synch and they took advantage. My night really came down to pitches down the middle and that was really it.”

Manager Bud Black, obviously thrilled that the Rockies broke out with four home runs, said he liked how Kuhl rebounded from the poor first inning.

“Chad can spin the ball … and his fastball has velocity,” Black said. “The thing that has bit Chad a little bit here lately has been his lack of fastball command. And we saw that tonight.”

Since pitching a masterful complete-game shutout of the Dodgers at Coors Field on June 27, Kuhl is 1-4 in nine starts, posting a 9.08 ERA, allowing 15 home runs over that span for an average of 3.40 home runs per nine innings.

Before Tuesday’s game, manager Bud Black reiterated that Gomber — part of the Nolan Arenado trade — will get his chance to be a starter. Tuesday night, Gomber came on as a middle reliever, giving up one run on one hit with two strikeouts. Gomber’s ERA is 5.56.

Meanwhile, Brewers right-hander Brandon Woodruff dominated the Rockies for seven innings, giving up one run on two hits, with two strikeouts and two walks. His one major mistake was giving up a solo homer to rookie Elehuris Montero in the third inning. It was Montero’s fifth homer in 37 games of his inaugural season.

Crazy Coors
Tuesday night was a wild one at Coors Field. Here are some of the highlights:

Colorado overcame a five-run deficit, matching the largest come-from-behind win of the season (July 3 vs. Arizona, 5-0).
The first-pitch temperature of 95 degrees was the highest in any September home game in franchise history. The previous high was 94 degrees, two times, including Monday.
Randal Grichuk’s walk-off hit was the fifth of his career and his third walk-off homer.
Grichuk’s six RBIs tied a career-high. The last time he did it was on July 18, 2015, as a member of the Cardinals, against the Mets.
Rookie Elehuris Montero reached base three times, going 2-for-3 with two runs scored, recording a double, home run, and an RBI while also drawing a walk.
Shortstop Alan Trejo went the game 3-for-4 and his three hits were a career-high.

On Deck
Brewers LHP Eric Lauer (10-6, 3.54 ERA) at Rockies LHP Kyle Freeland (7-9, 4.75)
1:10 p.m. Wednesday, Coors Field
TV: ATTRM
Radio: KOA 850 AM/94.1 FM

Freeland is coming off a hard-luck start at Cincinnati. He took a no-decision in the Rockies’ 3-2 loss to the Reds, despite allowing just one run on eight hits over 5 2/3 innings. He’s been roughed up at home recently, going 1-1 with an 8.27 ERA over his last four starts at Coors Field. The lefty has faced Milwaukee four times in his career, going 2-2 with a 2.52 ERA and holding the Brewers to a .205/.297/.341 slash line.

Like Freeland, Lauer is coming off an unfortunate outing. Last Friday at Arizona, Lauer was saddled with the loss in Milwaukee’s 2-1 defeat at Arizona. He surrendered just two earned runs on six hits over 6 2/3 innings. He struck out five and didn’t walk any. Lauer has gone 1-4 with a 7.40 ERA in 10 career starts vs. Colorado. He is 0-4 with an ugly 14.63 ERA in five career starts at Coors Field.

Trending: Brendan Rodgers’ 16 defensive runs saved at second base are the most in the majors and fifth-most among all infielders, Plus, his 2.2 dWAR (Baseball Reference) is tied for the fifth-highest among all major league position players. (Entering Tuesday’s game).

At issue: Entering Tuesday’s game, the Rockies’ 7.4% walk rate was the second-lowest in the National League and 25th in the majors. However, their 21.0% strikeout rate was the fourth-best in the NL and eighth-best in the majors.
