"It was great, especially not being able to get through the full three the other day and not reach pitch counts," Chavez said. "My whole goal was to go four, and that happened, and they let me go back out for the fifth."
The A's got right back in the game, scoring in the first when Billy Burns turned an infield single into a run two batters later and then putting three more on the board in the second. Eight of the first 14 batters for the A's collected hits, with Niuman Romero, Eric Sogard and Ben Zobrist all collecting RBI singles in the second.
Cain, who missed the last half of 2014 with elbow surgery, allowed four runs on six hits in his second outing of the spring, which lasted 1 2/3 innings. Chavez didn't walk a batter and struck out four in his second start of the spring.
Burns went 3-for-4 with his third triple of the spring in the top spot, and No. 2 hitter Eric Sogard and Romero in the No. 9 spot each had a pair of knocks. Romero also made a diving play at shortstop in the seventh inning that stirred up the crowd of 10,260 at Hohokam Stadium, the highest attendance mark in Oakland's first year at the facility.
McGehee added another double in the sixth and is off to a 10-for-20 start in his first Spring Training with the Giants.
A's Up Next: The A's will be back together as one unit Sunday after a split-squad trip to Las Vegas, and it will be right-hander Sonny Gray taking the mound for the second time this spring, meeting the Brewers at Maryvale at 1:05 p.m. PT, live on MLB.TV. Gray will be followed by veteran non-roster invitee Barry Zito. Gray allowed two earned runs on five hits in his two-inning Cactus League debut, and Zito has allowed four earned runs in 4 2/3 innings in one start and one relief appearance thus far.
