PHOENIX -- In the Rockies’ crazy four-game series at Coors Field this past weekend, they scored 48 runs, including at least nine in each of the contests. Yet, they only split the set with the Padres.

That’s because they also allowed 44 runs, including a season-high 16 on Friday.

It wasn’t just an off weekend for the Rockies’ rotation, as they entered Tuesday with the worst rotation ERA in the Majors this season. Outings like the one Antonio Senzatela delivered in their series-opening 8-1 win over the D-backs at Chase Field have been rare.

However, Senzatela got Colorado’s rotation -- and himself -- on track by allowing one run over 6 2/3 innings. The right-hander scattered seven hits and four walks while striking out five en route to the Rockies’ 2,000th franchise win.

“He was the key to the game, no doubt about it,” manager Bud Black said. “He held the game in his hands the whole way, so I thought it was outstanding.”

After posting a 5.81 ERA through the first two months of the season, Senzatela started June with back-to-back quality starts, tossing six innings of one-run ball in victories over the Blue Jays and Mets. He then allowed eight runs (six earned) in four innings in a loss to the Cubs last Thursday, which was followed by tough outings from each of the other four members of the Rockies’ rotation.

Senzatela thwarted several D-backs rally attempts, leaving two runners on base in three of his first four innings. After putting runners on the corners with no outs in the fifth, the right-hander allowed only one run -- an RBI fielder’s choice by David Peralta -- getting Adam Jones to ground into an inning-ending double play.

“We had a tough weekend, but I’ve just got on my mind, ‘It’s a new day, new opportunity to win a game,’ and we did a good job,” Senzatela said.

Senzatela matched his season high in innings, as he also went 6 2/3 frames on April 15, his first start of the year, and May 12, both against the Padres. But the righty was most pleased with this outing, which earned him his third win in four starts.

“It was one of the best games I’ve had all season,” Senzatela said. “I felt my fastball command was really good, and I felt confident.”

While Senzatela dealt, the Rockies continued to rake. Nolan Arenado drove in the club’s first three runs with a two-run homer in the first and an RBI double in the sixth, which started a four-run rally also featuring a two-run double from Ryan McMahon. Leadoff hitter Charlie Blackmon recorded his fifth straight three-hit game, moving one shy of the MLB record.

The Rockies collected 12 hits as they scored at least six runs for the seventh time in eight games.

“I thought that Senza restored order, I thought that that was critical,” Black said. “This was, I think, in my opinion, a big game. Here’s a team that’s coming off a nice road trip, we’re all sort of bunched there [in the National League West] trying to track down the Dodgers, they have some momentum and I think our offense kept it going and Senza restored order.”
