Rapid Reaction: Diamondbacks 8, Cubs 4

CHICAGO -- The Chicago Cubs lost for the second consecutive day on the heels of a six-game winning streak, falling 8-4 to the Arizona Diamondbacks on Sunday.

HOW IT HAPPENED: Edwin Jackson’s struggles continued as the right-hander gave up seven runs (five earned) on 12 hits over 5 2/3 innings. It was the third time Jackson had given up five or more earned runs in his 11 starts, while he has given up at least four runs six times. Jackson did manage to drive in a run with a fourth-inning single. Scott Hairston hit a two-run home run in the fifth inning. A day after allowing three walks and giving up a grand slam, reliever Carlos Marmol walked three more and gave up a run in a mop-up role. Wil Nieves had three hits and two RBIs for Arizona, while Gerardo Parra and Cody Ross each drove in a pair of runs for the Diamondbacks.

WHAT IT MEANS: The Cubs continue to lose games in which they held a lead at some point. Sunday’s defeat, when the Cubs led 1-0 after one inning, marked the 18th time they were defeated after once leading, matching the Los Angeles Dodgers for most in baseball. As it has been for both the Cubs and Dodgers this season, an unreliable bullpen is to blame. Sunday, however, the Diamondbacks scored three off Jackson in the second inning to erase the early lead, then scored three more in the sixth after the Cubs had rallied to tie it.

OUTSIDE THE BOX: It not only was the 500th career game for Starlin Castro, but Hairston hit his 100th career home run when he tied the game in the fifth inning on a two-run blast. In the first at-bat of his 500th game, Castro was hit in the knee on a pitch from Diamondbacks starter Patrick Corbin, finishing 0-for-3 with a run. Hairston’s 100th home run was his fifth of the season.

OFF BEAT: Hairston’s home run gave the Cubs a long ball in a season-high seven consecutive games. That tied the season-best home run streak from last year, a run that ended exactly a year ago Sunday. The Cubs have hit 13 home runs during the current streak (eight with a runner on base) after hitting 10 home runs during their seven-game stretch last season.

UP NEXT: After an off day Monday, the Cubs will open a brief two-game series at Anaheim, Calif., on Tuesday against the Los Angeles Angels. The Cubs will send right-hander Scott Feldman (5-4, 2.82 ERA) to the mound in the opener opposite Angels right-hander Jered Weaver (1-1, 3.71) in the 9:05 p.m. CST start from Angel Stadium.
