"I was just trying to see something out over the plate," Gosselin said. "Frederich has had a really, really good slider that he likes to back-foot, and he tried to get me on the heaters in too. So I was really just trying to see something out over the plate -- found a hole."
An ineffective Brown became the 14th pitcher in recorded history to walk three batters in an outing of 13 pitches or fewer. (Pitch counts weren't always recorded, however. For a better reference point, he's the 11th pitcher to do so in the past 20 years.)
Brown was one of the team's most reliable relievers early in the season before missing 85 games in two trips to the disabled list with right shoulder inflammation. Since his return, he has an 8.30 ERA in 11 games.
"That thing really lingered, and he was out longer than he probably anticipated," Rockies manager Walt Weiss said. "He's had a hard time."
The Rockies capitalized on an error by D-backs left fielder David Peralta to score a pair of runs in the first. In the early stages, it was that kind of night for Arizona, which committed a pair of errors and added a missed tag at third for good measure.
After the Rockies ran their lead to 3-1 on Carlos Gonzalez's 40th homer of the year, the D-backs scored runs in the third and fourth innings to tie things up. Rockies starter Christian Bergman worked five innings while D-backs lefty Robbie Ray tossed six before the game turned into a battle of the bullpens.
MOMENTS THAT MATTERED A second-half kind of guy: Gonzalez's third-inning homer was his 27th since the All-Star break, which matched Dante Bichette's club second-half record in 1995. Gonzalez also leads the NL with 60 RBIs since the break.
Out of a jam: Ray found himself in a tough spot in the fifth when a leadoff single by Charlie Blackmon turned into a double after an error by right fielder Ender Inciarte. Then, Blackmon would have been out at third, but Jake Lamb did not put the tag on him on a stolen base. Ray, though, was able to strand Blackmon at third and keep things tied at 3.
"When he got to third I told myself to limit the damage," Ray said. "He might score, but do everything you can to keep everyone else off base."
Basepath to nowhere:Jose Reyes was picked off first base just before Gonzalez's homer, and Blackmon was stranded two innings later. In the eighth, Nolan Arenado reached third after a double, before being picked off when DJ LeMahieu couldn't get down a safety squeeze bunt.
"I talked to DJ before he went up there and said if you see an opportunity, take it and push it to the right side. He's been really good at that," Weiss said of LeMahieu, who pushed across a run in Sunday's victory over the Dodgers on a similar play. "Nolan just got caught too far off the base."
The Rockies challenged a seventh-inning play at second, when the D-backs' Socrates Brito hustled out a double on a soft hit down the left-field line. But the call, that Brito beat the tag and maintained the bag, stood after Rockies manager Walt Weiss had challenged it.
WHAT'S NEXT Rockies: Righty Chad Bettis (8-5, 4.38 ERA) has been on a roll, and he'd like to use some of that magic in Phoenix against the D-backs at 7:40 p.m. MT. Bettis is 0-1 with a 10.80 ERA in four appearances (one start) at Chase Field.
D-backs:Chase Anderson will look to finish his season on a positive note when he starts Wednesday night's game against the Rockies at Chase Field. Anderson set a career high with 10 strikeouts in his last start.
