Cubs right-hander Edwin Jackson, who didn't take the mound until the second inning after arriving to the ballpark just 25 minutes ahead of first pitch, was on the hook for eight runs and nine hits in just 1 2/3 innings.
"I put in Google Maps and typed in Oakland Athletics Spring Training complex, and it took me to the old one," Jackson said. "I know it's crazy, but that pretty much sums it up."
Comeback hopeful Barry Zito, pitching in relief for the A's, strung together four more scoreless innings to bring his spring ERA down to 2.30. The lefty allowed just one hit and walked three with two strikeouts while continuing his bid for a big league roster spot.
Righty Blake Parker pitched the first inning for Chicago, surrendering Butler's third home run of the spring. Vogt, who also teamed up with Tyler Ladendorf for back-to-back doubles in the second, hit his homer in the third -- his first of the spring.
The six-run third inning was also highlighted by consecutive doubles from Ike Davis and Marcus Semien, which started a string of seven consecutive hits off Jackson.
Pomeranz struck out four but also walked four while laboring through 2 2/3 innings, allowing two runs on three hits in his fourth spring outing. The A's rotation candidate said afterward he was dealing with right hip tightness that hindered his ability to finish his pitches.
Cubs outfielder Jorge Soler notched an RBI single off Pomeranz in the first.
Davis and Vogt each finished with three hits for the A's, and Ben Zobrist two -- including a two-run, ground-rule double in the fifth.
Up next: The A's pay a visit to Maryvale Baseball Park on Wednesday to face Jimmy Nelson and the Brewers. Opening Day starter Sonny Gray will be on the mound for Oakland, with first pitch set for 1:05 p.m. PT on MLB.TV. Bullpen candidate Evan Scribner and switch-pitcher Pat Venditte are also scheduled to get in the game. Third baseman Brett Lawrie, who has been held out of each of the last two games because of general soreness, is expected back in the lineup.
