DETROIT -- The last of the Tigers eligible for free agency filed on Tuesday. Whether Kenny Rogers plans to sign on to pitch next year remains to be seen.

Rogers became of one the final players around the league to file when he submitted the necessary paperwork on Tuesday, one of the final few days in which to file.

That does not necessarily mean that the veteran left-hander will pitch in 2009. Players who retire often file if they're eligible. Fellow Tiger Todd Jones, who announced his retirement near season's end, filed earlier.

Rogers, who turned 44 years old on Monday, said near the 2008 season's end that he wanted to wait until the offseason before deciding on his future. He said at the time that if he did pitch in 2009, he wanted to do so in Detroit, where he has spent the last three seasons.

Rogers has not yet responded this offseason to e-mails about his situation. He serves as his own agent, having parted ways with Scott Boras in November before re-signing with Detroit on a one-year, incentive-laden contract.

Tigers president/general manager Dave Dombrowski said Monday that he expected Rogers to file this week, but that they did not know yet whether he plans to pitch next year. The Tigers hold exclusive negotiating rights with Rogers until Friday; Rogers can talk with other clubs before then, but not about financial terms.

Rogers went 9-13 with a 5.70 ERA in 30 starts for Detroit in 2008. He took a 6-6 record and 4.55 ERA into the All-Star break before struggling over the second half, including a 7.93 ERA and 83 hits over 59 innings, resulting in a .339 batting average and .967 OPS allowed.

The Tigers currently have at least two spots undecided in their rotation for 2009. Justin Verlander and Armando Galarraga are all but assured of rotation spots next year, manager Jim Leyland suggested, as is Jeremy Bonderman if he's healthy. Bonderman missed much of this past season following surgery to repair a blood vessel in his throwing shoulder.
