"I thought C.J. was terrific," manager Mike Scioscia said. "I liked the pace that he worked, and he was in the zone and ahead in counts, and his stuff looked really good."
A's starter Chris Bassitt impressed in his spring debut, too, posting two scoreless innings in his bid for a rotation spot. The right-hander struck out two and didn't walk a batter in front of a sellout crowd.
Luke Carlin, Alden Carrithers and Tyler Ladendorf began Oakland's comeback with an RBI each in the seventh, and Max Muncy hit a two-run double to climb within one in the eighth. Ladendorf tied the game with triple in the ninth and, after loading the bases, Nunez came through to give the A's the win.
Angels infielder Taylor Featherston was responsible for the first run of the day, driving home Daniel Robertson with an RBI single in the third inning. Teammate Efren Navarro added an RBI base hit in the fourth off reliever Ryan Cook, and Featherston again found himself in the middle of the action in the fifth, when he successfully executed a safety squeeze bunt.
Navarro recorded his second RBI of the day in the sixth on a double.
Angels up next: Right-hander Matt Shoemaker will see his first Cactus League action Sunday when he makes the start for the Angels in a home game vs. the Royals at Tempe Diablo Stadium at 12 p.m. PT. Shoemaker, last year's runner-up in American League Rookie of the Year Award voting, is coming off a debut season in which he went 16-4 with a 3.04 ERA in 20 starts and seven relief appearances. This will be the first of two spring meetings between the Angels and defending AL champion Kansas City.
