MESA, Ariz. -- Cuban third baseman Yasmany Tomas hit his first Cactus League home run for the D-backs on Tuesday, a loud, opposite-field shot to right field off A's starter Sonny Gray, who surrendered two runs in his spring debut as Oakland beat Arizona, 6-5, Hohokam Stadium.
Gray, likely Oakland's Opening Day starter, was tagged for five hits over 2 1/3 innings ahead of lefty Barry Zito, who came on in the fourth and cruised until he hung a curveball the led to a homer by Jake Lamb to lead off the sixth. Lamb added another homer in the eighth.
It's the second homer Zito has allowed in as many outings this spring. The comeback hopeful walked his next batter, Tomas, and allowed a double to former teammate Cody Ross.
Rule 5 Draftee Mark Canha homered for the A's in the fourth inning, and Ike Davis pitched in with two hits, including an RBI double. Ben Zobrist went 1-for-3 with two RBIs and Sam Fuld went 3-for-4 with an RBI and two runs scored for Oakland.
D-backs starter Trevor Cahill pitched two innings in his second Cactus League outing, allowing one run on four hits with one walk and two strikeouts.
Cahill's batterymate, Oscar Hernandez, notched an RBI hit in the second inning.
Up next for the D-backs: Left-hander Robbie Ray, acquired from the Tigers during the offseason, will get the start on Wednesday when the D-backs take on the Angels at Salt River Fields. Randall Delgado, who is out of Minor League options and is battling for either a spot in the rotation or bullpen, will also see action, as will one of the club's top pitching prospects, Braden Shipley.
Up next for the A's: Rotation candidate Kendall Graveman is scheduled for his second Cactus League start on Wednesday. The right-hander will face former A's outfielder Brandon Moss and the Indians in a 1:05 p.m. PT matchup at Hohokam Stadium. Behind the plate, Stephen Vogt is expected to catch five innings, after getting through three in his spring debut Monday.
