McMahon hit solo homers in his first three at-bats to become the 18th player in Rockies history with three long balls in one game. He added an RBI double in the 13th.
Matt Peacock (1-0) had a big major league debut for the Diamondbacks, tossing three innings, getting his first hit and scoring in Arizona’s three-run 13th. He entered to start the 11th after sitting in the bullpen for hours.
“It wasn’t that difficult,” he said. “I’m the waterboy down there so I’m making sure everybody’s got their water, ready to go into the game. When it was my turn the adrenaline started going and I didn’t even think about the cold.”
Temperatures hovered in the high 30s and players’ breath was visible by the eighth inning while fans were bundled up around the Coors Field stands.
“It was a lot colder the first six innings for me than once I went into the game,” said Vogt, who entered in a double switch in the sixth. “It was high 30s with some wind. Fortunately the wind died a little bit as the night went on. Coming out of Arizona and San Diego, it was weather that we have not experienced in quite some time. It was tough to keep moving and just stay warm.”
The teams each scored a run in the 10th and 12th before Arizona broke it open in the 13th. Vogt’s single to left field off Ben Bowden (0-1) drove in Eduardo Escobar. Peacock singled and Ketel Marte hit a two-run double.
McMahon and Dom Nunez went deep in the second inning and McMahon hit another in the fourth.
“I was pretty cold, I’m not going to lie,” McMahon said. “I felt good about my approach and I felt good about the way I was getting my swing off tonight.
“I’m never going to say I’m feeling it. This is a very humbling game. It’s a hard game. Right when you think you have it figured out, it likes to humble you. I like where I’m at mentally and the focus I’m giving my at-bats.”
The Diamondbacks got a run in the fifth on pitcher Luke Weaver’s RBI single. Christian Walker hit a two-run homer to tie it in the sixth and then Vogt put them ahead with another two-run shot in the seventh.
Colorado got a run back in the seventh and Sam Hilliard tied it at 5 with a two-out homer off Chris Devenski.
“We give up five home runs today but we didn’t have extra traffic on the basepaths,” Arizona manager Torey Lovullo said. “You can’t predict anything in this ballpark. Even on a day when it was freezing you can’t take anything for granted.”
Diamondbacks: SS Nick Ahmed (right knee inflammation) is scheduled to hit in the batting cage soon. … RHP Zac Gallen (right forearm fracture) will throw 70-80 pitches in a bullpen session Wednesday.
Rockies: INF Josh Fuentes (sore left wrist) did not start but pinch-hit in the 10th and stayed in the game. … OF Raimel Tapia returned after being out of Sunday’s starting lineup with whiplash suffered in Saturday’s game against the Los Angeles Dodgers. He had a single.
SORIA TO IL
Arizona placed right-handed reliever Joakim Soria on the 10-day injured list with a left calf strain, retroactive to Monday. Soria was hurt covering first base against San Diego on Sunday.
“It’s severe enough that he is going to be out 10 days. We were hoping that it would be a day-to-day but that wasn’t the case,” Lovullo said. “He’s got 10 days to recuperate and we’ll re-evaluate at that point or as we’re getting closer to that day.”
The Diamondbacks activated Peacock from the taxi squad and he made his big league debut when he pitched the 11th inning.
The Diamondbacks will send out LHP Madison Bumgarner (0-0, 13.50 ERA) to face Rockies RHP Antonio Senzatela (0-1, 18.90) on Wednesday night in the second game of the three-game series.
