Pitcher Hector Santiago moved from the White Sox to the Angels, outfielder Adam Eaton from Diamondbacks to Chicago, and left-hander Tyler Skaggs from Arizona to Los Angeles.
Arizona also will receive player to be named or cash from each of the other clubs in the deal made at the winter meetings.
Trumbo hit .234 with 34 homers and 100 RBIs this year, getting much of his playing time at first base because Albert Pujols was hurt. But he was deemed superfluous by Los Angeles, which needs starting pitching behind Jered Weaver, C.J. Wilson and Garrett Richards.
Santiago was 4-9 with a 3.56 ERA in 23 starts and 11 relief appearances. His fastball velocity has dipped from 93.8 mph in 2011 to 92.8 in 2012 to 91.8 last season, according to fangraphs.com.
Eaton hit .252 with three homers, 22 RBIs and 44 strikeouts in 250 at-bats for the Diamondbacks this year, when he also played with three minor league teams.
Skaggs went to Santa Monica High School, was taken by the Angels with the 40th overall selection of the 2009 amateur draft and was dealt to the Diamondbacks in August 2010 to complete the trade that brought Dan Haren to Los Angeles.
Skaggs made his big league debut in 2012, when he had six starts, but spent much of this year in the minors. He was 2-3 with a 5.12 ERA in seven starts this year for Arizona, leaving him with a 3-6 career mark.
OAKLAND: The Oakland Athletics found a trade partner for pitcher Brett Anderson and his big salary.
The A’s dealt the left-hander and cash to the Colorado Rockies for lefty Drew Pomeranz and minor league right-hander Chris Jensen on Tuesday.
Two-time AL West champion Oakland had been looking to move Anderson, who is due to make $8 million this season and has a $12 million contract option for the 2015 season. That includes a $1.5 million buyout.
The 25-year-old Anderson was the Athletics’ starter on opening day this year. He went 1-4 with a 6.04 in five starts and 16 appearances, finishing up as a reliever in an injury-interrupted season.
“Thanks to the A’s Organization and Fans for everything,” Anderson posted on Twitter. “I’ll nothing but fond memories of my time there.”
Anderson, a second-round draft pick by Arizona in 2006, has been plagued by injuries in recent years.
He returned in the summer of 2012 after missing 14 months following Tommy John elbow surgery. During his lengthy rehab, Anderson worked to improve his fitness and lost more than 20 pounds. He then missed four months this past season with a sprained right ankle and stress fracture in his right foot.
TANAKA: Rakuten Eagles President Yozo Tachibana says no decision has been made on whether star pitcher Masahiro Tanaka will be made available to Major League Baseball teams.
The New York Yankees are among the team interested in Tanaka, who was a record 24-0 in Japan’s regular season. Major League Baseball and Nippon Professional Baseball have an agreement in principle on a new posting system. If ratified, there would be a $20 million cap on the fee going to Japanese clubs for players, and any MLB teams bidding the specified price would be able to compete to sign a player.
There is a possibility that Rakuten could ultimately decide not to post Tanaka because of the new fee cap. Tanaka is eligible to be a free agent in two years.
