The Tigers on Monday night clinched the American League Central when they beat the Royals.
Detroit was able to hold off the White Sox, but it took until the final series of the season to do so.
While Turner is with the Marlins, he did pick up a key win for Detroit. On July 22, the right-hander pitched 5 1/3 innings and allowed three runs, while collecting a win against the White Sox.
The next day, Turner was part of a package of prospects traded to the Marlins for Omar Infante and Anibal Sanchez.
"Obviously, there are a lot of guys over there who I'm really rooting for," Turner said. "It's good to see them be able to win the division. I think they will be a scary team in the playoffs."
Turner is projected to be a big part of the Marlins' rotation for years to come. On Tuesday night, he was impressive in a season-high 7 2/3 innings against the Mets.
Turner gave up one run on three hits, but he wasn't involved in the decision. Miami, after watching a three-run lead disappear in the eighth inning, prevailed , 4-3, in 11 innings.
Still, Turner keeps tabs with some of his former teammates in Detroit.
"I talked to a few of the guys," he said. "Obviously, they are excited. They should be. It was a long season for them. They battled the whole season. They deserve to be where they are at."
