DENVER -- Following a three-game sweep at the hands of the Braves over the weekend in Atlanta that increased the D-backs' losing streak to four games, manager Torey Lovullo talked about his team needing to “regroup the troops” and get back on track.

Circumstances seemed to line up for that given that the D-backs were headed to play the 2-8 Rockies, who were set to start Kyle Freeland -- the same Freeland they knocked around for 10 runs on Opening Day. Meanwhile, the D-backs had their ace Zac Gallen, who had allowed just one earned run in his first two starts, on the mound.

But baseball doesn’t follow a script and seldom goes the way you think it will.

Such was the case Monday in the series opener as the Rockies rallied to beat the D-backs, 7-5. Arizona has now dropped five straight and six of seven since taking three of four games from Colorado in that season-opening series.

“I can't put my finger on it right now,” Lovullo said when asked why his team has struggled. “But we're gonna keep trying.”

In the first two games of the Braves series, the D-backs had early leads they let slip away, including a six-run advantage on Saturday. On Monday, they were up 4-1 heading into the bottom of the fourth before the Rockies rallied for two in the bottom half and three more in the sixth, relinquishing the lead and never reclaiming it.

“Things aren't going our way but they will,” Lovullo said. “It's gonna turn around for us at some point. The storm is coming. The storm is hovering. And when it comes, it's gonna be fun for all of us to watch. You’ve got to budget for the times it doesn't go good.

“We've lost five games in a row. We all know that's no fun, but we'll get there. I can't figure out what's going on. This is a good team. This is a very, very good baseball team and they're hungry. We just can't seem to get things moving in the right direction right now, but we will.”

Gallen did his part, striking out 10 without issuing a walk over five innings of three-run ball. The right-hander used an interesting mix to get there, throwing a whopping 40 curveballs out of his 108 pitches, tied for the most he's thrown in a game.

Normally, pitchers stay away from their breaking stuff at Coors Field because the altitude limits the break of them, but it was the opposite for Gallen.

Though he usually favors more of a diverse mix, Gallen threw 87 pitches that were either four-seam fastballs or curveballs.

“Just knowing what I've done here and how I've had success, it seems that my curveball tends to play up a little bit here,” Gallen said. “I don’t know the reason. Maybe it gets a little bit sharper just because I'm cognizant of the altitude and I just have to kind of, as they say, rip on it.

"I just felt like I was getting some pretty good responses from the hitter so we just kind of stuck with that. It's a place where I try not to get beat with my third and fourth pitches. I felt like fastball/curveball was working for me for the most part and stuck with it.”

The D-backs are going to stick with their same approach as well. They are going to stay the course for right now as they wait for injured players like pitchers Eduardo Rodriguez and Paul Sewald and shortstop Geraldo Perdomo to return and for when lefty Jordan Montgomery is stretched out enough in the Minor Leagues to join them.

“We've been playing really good baseball,” third baseman Eugenio Suarez said. “But not going our way right now. So we just got to keep going. Come tomorrow and win another game and try the tie of the series and then win and go home.”
