Former Arizona Diamondback Mark Reynolds hit a two-run homer with two outs in the bottom of the ninth inning to give the Colorado Rockies a 9-7 victory over the Diamondbacks on Sunday.
Carlos Gonzalez had a grand slam, and Trevor Story and Charlie Blackmon also went deep for the Rockies, who earned a split of the four-game series.
Story was hit by a pitch leading off the ninth. Silvino Bracho (0-1) retired the next two batters before Reynolds drove a 2-1 fastball an estimated 464 feet to left-center for his eighth home run of the season.
It was Colorado's first walk-off win since Sept. 26, 2015.
Arizona finished with 56 hits to set a club record for a four-game series. The previous best was 53, done twice against Colorado. The last time it happened was 2012.
Carlos Estevez (2-5) struck out two in a hitless inning for the victory.
Paul Goldschmidt had two hits and four RBIs for Arizona. Goldschmidt has reached base in 48 straight games against the Rockies, a mark that ties him with Mike Piazza, who did it from 1995-99.
Arizona led 3-1 after three innings and increased the margin to 5-1 on Goldschmidt's two-run triple in the fourth. The Rockies rallied in the fifth to take a 6-5 lead on Gonzalez's grand slam off starter Patrick Corbin.
It was Gonzalez's 16th homer of the season and the fifth career slam.
Goldschmidt gave the Diamondbacks the lead again in the sixth with a two-run single off Rockies starter Chad Bettis. Story answered with a solo homer in the seventh, his 19th, to tie it.
TRAINER'S ROOM
Diamondbacks: SS Nick Ahmed is on baby watch and did not start. Manager Chip Hale said Ahmed had an afternoon flight to Phoenix booked in case his wife went into labor, but it proved unnecessary. Ahmed entered as a pinch-hitter in the seventh and remained in the game. ... Hale said Chris Owings (left foot plantar fasciitis) "is not where we thought he'd be" in his rehab. Hale expressed hope that Owings could be back by the end of the Diamondbacks' upcoming 10-day homestand.
Rockies: 2B DJ LeMahieu left in the top of the sixth with a bruised left knee. He was hurt making a sliding attempt at Goldschmidt's two-run single. ... LHP Jake McGee (sprained left knee) threw a bullpen session. Manager Walt Weiss said McGee could be sent on a rehab assignment "in the next few days."
UP NEXT
Diamondbacks: LHP Robbie Ray (4-6, 4.59 ERA) takes the mound for the first of a three-game series against the Phillies on Monday. Ray won in Philadelphia on June 17.
