Nolan Arenado Completes Cycle vs. Giants with Walk-Off Home Run

Nolan Arenado completed his first career cycle in the most thrilling fashion possible Sunday, belting a three-run walk-off home run to give the Colorado Rockies a 7-5 win over the San Francisco Giants.

Arenado's homer was part of a four-run ninth inning against Giants reliever Mark Melancon, who entered the ninth looking to preserve a 5-2 lead. The Rockies third baseman went 4-for-5 on the day and drove in four runs.

It's the fourth cycle of the 2017 season, as San Diego Padres first baseman Wil Myers, Washington Nationals shortstop Trea Turner and Texas Rangers outfielder Carlos Gomez previously pulled off the feat in April. Rockies pitchers gave up two of those three other cycles (Myers, Turner).

Arenado is the eighth Rockie to hit for the cycle and first since Michael Cuddyer in 2014. He began the game with a first-inning triple, singled in the fourth and then hit an RBI double off Giants starter Ty Blach in the sixth.

Raimel Tapia, Charlie Blackmon and DJ LeMahieu all singled in front of Arenado in the ninth, leaving him with runners on first and third. He then cracked a 374-foot home run to left field on Melancon's first pitch to send the Coors Field crowd into an uproar.

Sitting first place in the NL West at 46-26, the Rockies swept the Giants and will carry a five-game winning streak into their game against the Arizona Diamondbacks on Tuesday.
