The Diamondbacks actually took a 2-0 lead, in the first inning - with two outs, Paul Goldschmidt walked, and Jake Lamb then launched his tenth home-run of the year. However, that would be the only hit Arizona would manage off seven innings of Jake Hammel. The Cubs struck back immediately, Edwin Escobar allowing a home-run to the very first batter he faced, but then settled down through the end of the third inning.
It was the fourth that proved the turning point. Half the D-backs defense surrounded a pop-up and watched it land. A walk followed, and a ground-rule double into the ivy tied the game. With two outs, Chip Hale opted to walk David Ross to get to the pitcher's spot, but Hammel hit the pitch from Escobar back up the middle. It would have been a tough play, but the ball hit the second-base bag, and two runs scored, making it 4-2 to the Cubs.
Arizona got a run back in the eighth on a Yasmany Tomas home-run, and loaded the bases, but Rickie Weeks Jr lined out, pinch-hitting against a left-hander for Jake Lamb. The bullpen allowed one run over 4.1 innings of work, a solo homer off Daniel Hudson in the eighth, with Randall Delgado tossing 2.1 shutout innings. thunderpumpkin87 will be along in a bit with full details in his guest recap.
