Ryan Waldschmidt's walkoff HR lifts Diamondbacks past Cubs

Rookie Ryan Waldschmidt delivered a dramatic two-run walkoff home run with two outs in the ninth inning, lifting the Arizona Diamondbacks to a 5-4 comeback victory over the Chicago Cubs on Tuesday night at Chase Field in Phoenix. The hit capped a resilient rally from a four-run deficit and kept the Diamondbacks in the hunt for a National League Wild Card spot.

The Cubs held a 4-0 lead heading into the bottom of the eighth inning, having been dominant on both sides of the ball. Starter Clay Holmes had limited Arizona to just two singles over seven scoreless innings, and Chicago's offense had been on a historic tear, scoring 30 consecutive runs and throwing 23 consecutive scoreless innings since the second inning of their previous game. Ian Happ had broken a scoreless tie with a three-run homer in the fourth.

Arizona's comeback began in the eighth when Jordan Lawlar was hit by a pitch and replaced by pinch-runner Jorge Barrosa. After a walk, Gabriel Moreno hit a check-swing double that struck the first-base bag, driving in Barrosa. Geraldo Perdomo then singled to center, plating two runs and cutting the deficit to 4-3.
