"This is probably going to be it. This is probably going to be it," said Dunn, speaking to reporters during Sunday's game against the Tigers at U.S. Cellular Field. "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.
"I don't think [I could be talked out of retirement]. Kind of the way that everything's gone down, and the family. I think you know when it's time. I feel like now is as good a time as any."
Dunn departs for Oakland, the fifth team of his career, with 460 home runs, 1,158 RBIs and 1,311 walks. He also has 2,352 career strikeout and 1,976 regular season games without seeing the postseason. Dunn hit .201 with 106 homers and 278 RBIs during parts of four years with the White Sox, including a home run off of Max Scherzer on Saturday in the first game of a split doubleheader in his final game with the White Sox.
"It was fun. One of the main reasons was one of my good buddies, one of the best pitchers in the league [Chris Sale] gave up three runs, which nobody would have seen coming," said Dunn of his finale. "As many times as we haven't scored runs for him, he pitched well. To battle back and win a game for him, that's pretty huge."
