Rapid Reaction: Giants 8, Cubs 3

CHICAGO -- The Chicago Cubs lost to the San Francisco Giants 8-3 on Wednesday night. Here's a quick look at the game.

How it happened: Edwin Jackson gave up seven runs in the first three innings as the Giants pulled away early. They scored four runs in the first inning with Pablo Sandoval, Joe Panik and Travis Ishikawa racking up the RBIs. The Cubs struck back when Chris Valaika hit his first home run as a Cub, a two-run shot in the second. But three more runs in the third by the Giants, including another RBI by Ishikawa and a two-run home run by Andrew Susac, put the game away. Hunter Pence hit a long ball the next inning. Luis Valbuena went deep in the eighth to complete the scoring.

What it means: There's simply nothing left to say about Jackson that hasn't been said. He lasted only 2⅔ innings, giving up eight hits, two walks and seven runs. His ERA is 6.09, by far the highest in baseball among regular starters. No other pitcher who qualifies for the ERA title has one over 5.00.

Turner for Thursday: Jacob Turner will take over on the mound for the Cubs when they resume play in their suspended game with the Giants at 4:05 p.m. CT on Thursday.

What's next: After the completion of their suspended game Thursday afternoon, the teams will play the series finale later in the night with Travis Wood (7-10, 4.86 ERA) taking on Madison Bumgarner (13-9, 3.14).
