PHOENIX -- The A's hit four home runs on Sunday, leading to a 12-6 victory over the Cubs at Phoenix Municipal Stadium.
Chris Young, Josh Donaldson and Adam Rosales (twice) all homered for Oakland, which pounced on Cubs starter Scott Baker for three hits -- including Young's three-run homer -- and two walks in just one-third of an inning, spoiling the right-hander's spring debut.
Baker, who had been sidelined for 11 months while rehabbing from Tommy John surgery, made only 23 pitches before departing, though he was scheduled for two innings. He's not expected to be ready to pitch in the regular season until mid-April.
It was right-hander Cory Wade who surrendered the A's second homer of the day, this one coming off the bat of Donaldson with two runners on base in the third. Then, in the seventh, Rosales launched a two-run go-ahead shot off reliever Jason Berken. Rosales doubled his output with another two-run homer in the eighth.
The A's also got four hits from Eric Sogard, who is now 15-for-30 and keeping his name in the second-base competition.
Chicago, meanwhile, scattered four runs on eight hits off lefty starter Tommy Milone, who walked none and fanned two in his 4 2/3-inning outing.
Outfielder Dave Sappelt homered off the southpaw in the second and again caused damage in the fourth, notching a two-run single.
In the fifth, shortstop Javier Baez collected an RBI double off lefty Hideki Okajima, and the Cubs put two more on the board in the sixth, again getting to the reliever by way of a two-run homer from Brent Lillibridge.
Up next: After three days of split-squad games, the Cubs have two weeks to fine-tune before the start of the regular season. On Monday, they'll travel to Peoria to face the Padres. Expect to see Javier Baez and Jorge Soler in the lineup backing Edwin Jackson, who will make his fourth Cactus League start. Jackson has given up three runs on seven hits over nine innings.
