One more shot at the playoffs for Adam Dunn before he says he's probably done.
The White Sox also sent cash to Oakland and acquired minor league pitcher Nolan Sanburn. Because the deal was made before Sept. 1, Dunn will be eligible for the postseason if the Athletics reach the playoffs.
Dunn, 34, has played more games — 1,976 — without reaching the postseason than any active major league player. This is his 14th season and, with a contract set to expire, said he's planning to retire after this year.
Dunn waived his no-trade clause and approved the deal.
"This is probably going to be it," he said. "I think that also weighed a lot, too. This is an opportunity. I've been playing a long time and haven't got this opportunity, so I'm going to try to make the most of it."
Dunn is hitting .220 with 20 home runs and 54 runs batted in. He has also played for Cincinnati, Arizona and Washington.
"We're trying to do whatever we can to get some offense going here," Oakland Manager Bob Melvin said. "The guy has a history of hitting homers and getting on base, and I know he's excited about being with us."
Broxton, 30, is 4-2 with a 1.86 earned-run average and seven saves in 51 appearances this season.
Broxton is scheduled to join the team Monday in Chicago and is eligible for the postseason roster because the move was made before Sept. 1.
