J.D. Martinez belted his seventh home run in 18 games with the Diamondbacks while Paul Goldschmidt, who registered his first career three-homer effort at Chicago on August 3, ended his six-game hitting streak by going 0-for-5. Adam Rosales scores. Ketel Marte reaches on a fielder's choice to shortstop, advances to 2nd. J.D. Martinez to third. Paul Goldschmidt scores. Throwing error by Javier Baez.
Drury, formerly an everyday regular but starting for the first time in seven games because of his defensive liabilities, drove a two-run double to center field to make it 4-0. Patrick Corbin called out on strikes. Walker, who never has faced Chicago, has posted a 4.14 ERA in eight starts at home - more than a full run higher than his 3.11 road mark.
RHP Jake Arrieta (11-8) starts Sunday's series finale for the Cubs and is 4-2 with a 2.18 ERA in seven starts since July 2.
Diamondbacks seventh. David Peralta doubles to right field.
Peralta finished it off with an inside-the-park homer in the eighth - his 12th homer of the season - against reliever Jason Grimm, a shot off the center field wall that ricocheted wildly and allowed Peralta to score easily. He escaped trouble in the opening inning when Ian Happ hit an inning-ending groundout with runners at the corners. The slide began at the beginning of the month, when the Cubs dropped the last two contests of their three-game home set against the Diamondbacks. Daniel Descalso doubles to left field.
1 run, 2 hits, 0 errors, 1 left on. On Saturday, he consistently shut down Cubs threats while scattering five hits in 6 2/3 scoreless innings. Jon Jay scores. Victor Caratini scores. Anthony Rizzo hit an inning-ending flyout with the bases loaded. Kris Bryant to third.
