Nolan Jones hit a walk-off home run into the second deck in the bottom of the ninth inning, and the Colorado Rockies beat the San Diego Padres 5-4 after a rain delay in Denver on Sunday.
Coco Montes homered among his two hits in his major league debut and Ezequiel Tovar and Ryan McMahon also went deep for Colorado.
Jake Cronenworth homered and Fernando Tatis Jr. had two hits for San Diego.
The Rockies trailed 4-3 entering the ninth, and with a heavy rain falling McMahon led off with his 10th homer, a shot off Tom Cosgrove. The game then went into a 1 hour, 25-minute delay. After play resumed Brent Honeywell (2-4) got the first two batters before Jones smacked a 472-foot homer.
It was his fourth of the season.
San Diego's Blake Snell allowed a run on three hits and struck out 12 in seven innings, both season highs. He stayed in the game despite taking a line drive by Randal Grichuk off his foot in the seventh inning.
