Cleveland's versatile veteran seems to be following a similar script, as he collected six home runs and 19 RBIs in 56 spring at-bats last year.
The Indians reached the board quickly against A's starter Andrew Werner, acquired from the Padres alongside infielder Andy Parrino this offseason in a trade that sent righty Tyson Ross to San Diego.
Werner issued a leadoff walk to Michael Bourn, who advanced to third on a routine ground ball off the bat of Raburn that A's first baseman Brandon Moss threw away. With runners at the corners, Werner induced a double-play ball from Michael Brantley, allowing Bourn to score.
The left-handed Werner enjoyed a clean second frame, finishing his spring debut having allowed one unearned run with one walk and one strikeout.
Cleveland upped its one-run lead to three in the third, when Brantley followed Raburn's RBI hit with one of his own, via a double to left field.
Meanwhile, righties Justin Masterson and Ubaldo Jimenez, who combined for 32 losses last season, looked like winners on this day, with each firing two shutout innings. Masterson, who started the game, was perfect in his debut, striking out one and relaying on five groundouts, while Jimenez offered up two hits with one walk and two strikeouts.
"Masty was good," Indians manager Terry Francona said. "He was down. He was in the zone. He threw a couple changeups. I thought Ubaldo had a lot of life on his fastball. I think it was progress, which is really good."
Both Masterson and Jimenez were pleased to get off to a good start.
"Definitely," Jimenez said. "It took a load off my shoulders. Even last year, even in Spring Training, I couldn't do anything right."
Southpaw Hideki Okajima made his unofficial A's debut in relief, allowing one hit and walking one in an inning of work. Okajima pitched in Japan last season, making this his first appearance back in America since May 2011.
"Even though I'm a veteran, it's been awhile since I've been on an American mound," Okajima said through a translator." So even though I was a little nervous, it turned out OK."
Former A's player Matt Carson hit a two-run homer off Oakland pitching prospect Sonny Gray in the sixth to make it 5-0, before Oakland finally joined in on the scoring by way of a two-run homer from outfielder Shane Peterson.
The long ball came again in the seventh, this time from the Indians' Yan Gomes, who drilled a three-run homer off Oakland lefty Jordan Norberto over the left-field wall.
Parrino cut into the Indians' lead in the seventh with an RBI double, and outfield prospect Michael Choice hit a two-run homer off right-hander Frank Herrmann, who is fighting for a job in Cleveland's bullpen.
Up next for Indians: The Tribe will host the rival Royals in a 3:05 p.m. ET Cactus League tilt at Goodyear Ballpark on Tuesday. In what Francona described as a "bullpen day," right-hander Matt Albers will take the ball as the starter. Francona gave the nod to Albers, who is a leading candidate for a relief role, because he felt the pitcher could handle the assignment without altering his approach. All-Star closer Chris Perez is also scheduled to pitch, along with relievers Bryan Shaw and Scott Barnes, among others.
