DENVER -- The D-backs fought through the twists and turns of a classic Coors Field slugfest to top the Rockies, 9-7, on Wednesday and win two of three games in a series featuring three straight come-from-behind victories.

“This is a gut check, and I'm proud of our guys,” manager Torey Lovullo said of the dramatic series win. “After losing the first day here, we came out and won two really tough ballgames. We didn't shut down.”

Arizona struck first, taking an early lead on Christian Walker's two-out, two-run homer to center. Walker has been a Rockies killer on the trip. He was 6-for-11 with four homers, a double, nine RBIs and three walks in the series. Two of those home runs and four of those RBIs came in Wednesday's finale.

“I'd say it's a battle for myself, not trying to do too much,” Walker said of his success. “Sometimes, I'm up there trying to hit a ball to the moon, and it's not a very efficient mindset as far as pitch selection or even body movement.

"I’m just trying to stay calm, trying to stay loose, trust my strength, trust what I see, and rely on the guys around me. Everybody's putting together really good at bats. There's a ton of protection in this lineup right now. It's a lot of fun.”

Slade Cecconi left his second big league start in the fifth with a runner on a 2-1 lead, though Colorado scored a pair in the inning after Cecconi left. He pitched four complete innings and allowed two runs on four hits and three walks with four strikeouts and a hit batsman.

“It was a solid effort on a day where we needed him to pitch into the fifth inning, and he did a great job for us,” Lovullo said.

Colorado starting pitcher Austin Gomber lost sight of the strike zone in the sixth, giving up three walks after not issuing a free pass all day. 

All three walks came around to score as he walked Buddy Kennedy before Nick Ahmed’s bases-loaded triple.  Ahmed tried for an inside-the-park grand slam but was easily thrown out at home on a 9-3-2 play initiated by Jones in right field.

“It was a spot-on, right-center approach with men in scoring position,” Lovullo said. “It's a long fly ball off the top of the wall, and [Ahmed] prepares for that. He just continues to ready himself for those moments, and it was a huge play for us. The Walker home runs and the Ahmed triple off the top of the wall were the catalyst for helping us win this game offensively.”

The Rockies plated four runs in the bottom of the inning to take a 6-5 lead before the pendulum swung back Arizona’s way one more time in the top of the eighth when Tommy Pham hit a leadoff single to left off Tyler Kinley and Walker launched his second home run of the game for an 8-7 lead. It was his third consecutive game with a homer, and his fifth in his last five games.

“Christian had an incredible series,” Lovullo said. “Four home runs -- and big home runs, very timely home runs where you think, ‘Here's our guy and let’s see if we can push across crooked numbers,' and he did. He's locked in. He's hitting the ball very well, and without him we wouldn't be in the position we’re in.”

Conquering Coors Field is nothing new to Walker.  He now has 13 homers in the Mile High City, tied with L.A.’s Max Muncy for the most of any active visiting player since 2018.  In 15 games since 2020, he is hitting .393 (24-for-61) with eight homers, five doubles, 22 RBI, 15 runs, and 10 walks.

“Knowing that I don't have to hit a ball 112 miles an hour to get out of the park [helps],” Walker said. “It's nice to feel like you get rewarded for just taking a clean swing, putting the barrel on the ball.  I'm a much better hitter under those circumstances, so when I can take a little pressure off myself and take a little bit of the intensity level out, things get way more efficient.”

Paul Sewald gave up a leadoff single up the middle to pinch-hitter Charlie Blackmon, then retired three in a row to notch his 25th save and a series victory over the Rockies.  It was the 250th win over Colorado, the most wins the D-backs have amassed against any team.

The victory put the D-backs back over .500 (61-60) and kept them in contention for an NL Wild Card playoff berth.
