The Tigers found a taker for Dontrelle Willis.
Detroit dealt the lefthanded pitcher and cash to the Arizona Diamondbacks for righthander Billy Buckner, who was sent to Triple A Toledo.
The 28-year-old Willis was designated for assignment on Sunday, giving the Tigers up to 10 days to make a move with him. He was making $12 million this year.
"We are paying a substantial portion of that salary," said Detroit general manager Dave Dombrowski, adding a couple of clubs showed interest.
Willis was 1-2 with a 4.98 ERA in eight starts and one relief appearance this season.
"I'm just excited to get a fresh start," Willis said on a conference call. He was given the starting nod Saturday against visiting Colorado.
"He's an energetic guy who loves to play," Arizona manager A.J. Hinch said. "He wears his heart on his sleeve and has a lot of charisma. He had a lot of success early in his career for his play and his personality and his approach. He brings a fresh outlook to our team, and a fresh personality."
The former NL Rookie of the Year, All-Star and 22-game winner helped Florida toward the World Series championship in 2003, but failed to remotely regain that form in two-plus seasons with the Tigers.
He joined the team as part of the trade that brought Miguel Cabrera to Detroit after the 2007 season, and signed a 3-year, $29 million contract extension.
Willis was 2-8 with a 6.86 ERA in 24 games - 22 starts - and was put on the disabled list twice last season with what the team called an anxiety disorder.
He didn't agree with the diagnosis last season and still didn't earlier this season.
"I'm not on any kind of medication," Willis said a month ago.
As poorly as he has pitched, his next start likely will be for the Diamondbacks soon.
The Diamondbacks have a baseball-high 5.89 ERA, and Willis becomes their first lefty.
Buckner was 0-3 with an 11.08 ERA in three starts, which Dombrowski said were "not good," for Arizona this season. The 26-year-old righty has spent 4 years in the majors, going 4-6 with a 6.40 ERA in 13 starts last season for the Diamondbacks.
