Willy Adames hit a grand slam in a seven-run fifth inning, Bryce Eldridge also homered among his four hits, and the San Francisco Giants routed the Colorado Rockies 19-6 in Denver on Sunday.

Jung Hoo Lee had a career-high five hits -- two in the fifth inning -- Jesus Rodriguez homered, Rafael Devers finished with three doubles and a single and Casey Schmitt had three hits for San Francisco, which snapped a five-game skid.

The Giants finished with a season-high in runs, hits (25) and extra-base hits (13). Colorado native Jonah Cox, called up from Double-A before the game, made his major league debut as a pinch runner in the eighth inning and doubled in the ninth for San Francisco.

Reliever Caleb Killian (2-3) got the win for the Giants with a scoreless sixth inning. Right-hander Joel Peguero left the game in the eighth after hobbling while trying to field Tyler Freeman's infield single.

Freeman had three hits and Kyle Karros and Troy Johnston had two hits apiece for Colorado, which totaled 10.

San Francisco took a 2-1 advantage after the second and then chased starter Tanner Gordon (0-1) in the fourth. Eldridge led off with his second double and Daniel Susac was hit in the head by a Gordon curveball but remained in the game. Brennan Bernardino relieved Gordon and surrendered an RBI single to Schmitt.

Luis Arraez brought home another run with a sacrifice fly to close the book on Gordon, who allowed four runs on six hits in three-plus innings.

The Rockies made it 4-3 in the bottom of the inning on starting pitcher Robbie Ray's two errors on Willi Castro's broken-bat comebacker. Colorado's Karros (single) and Chad Stevens (walk) scored on the play.

The Giants broke the game open in the fifth against righty Zach Agnos. Lee and Matt Chapman doubled. Two outs later, Drew Gilbert tripled, Schmitt singled and Devers doubled. Agnos intentionally walked Arraez before Adames slammed a full-count fastball into the seats in left for an 11-3 lead.

Colorado scored two in the bottom of the fifth, the Giants added a run in the sixth, two in the seventh, three in the eighth and two in the ninth. The Rockies scored one run in the seventh.
