Power play: A's acquire slugger Adam Dunn from White Sox
AUG 31, 2014 11:41a ET
Dunn had to approve the deal because of his no-trade clause.
Dunn's arrival could help to boost an Oakland offense that has sputtered since the team dealt slugging outfielder Yoenis Cespedes to the Boston Red Sox in the July 31 trade that netted left-hander Jon Lester and outfielder Jonny Gomes.
The A's led the majors in runs scored through July 31, but they are tied for 20th in that category since the trade.
In 106 games this season, Dunn is hitting .220/.340/.433 with 20 homers and 54 RBI. During his 14-season major-league career, he has 460 homers. He never has played in the postseason.
FOX Sports 1 Insider Ken Rosenthal reports the San Francisco Giants were among the other teams making a late push for Dunn. Players acquired after Sunday's 11:59 p.m. ET deadline aren't eligible for postseason play with their new teams.
Sanburn is 3-1 with a 3.28 ERA and 73 strikeouts in 72 relief appearances (71 1/3 innings) in Single-A this season.
