I've been running a modern fictional league called the American Premier League that began in 1996 with 12 teams. Just finished the 2013 season, with 16 teams.
Manuel Casdenito has been a mainstay of the league since its inception. He just turned 40 years old. On September 3, 2013, he became the first player in the APL to reach 3,000 hits. He currently sits at 3,014. The closest player is a 37-year-old active player with 2,566. Casdenito has won the league championship five times with two different teams.
Casdenito started as a 22-year-old center fielder for the 1996 Colorado Rapids, where he logged the first of three consecutive batting titles, in addition to winning the MVP in '97. The Rapids won the APL title in '97 and '98.
The Rapids let him walk and he signed a four year deal with the Chicago Firebirds, where he picked up another batting title and MVP award in 2001. The Firebirds moved him to the infield, where he primarily played second base.
The Firebirds also let him walk, and he wound up signing two long term deals for a total of 9 years with the Texas Twisters (subsequently rebranded to the Dallas Vaqueros). He initially split time between second and third base, but eventually made a more permanent transition to right field. The Twisters won three consecutive league championships in 2003-2005. Casdenito racked up three more consecutive batting titles in 2006-2008.
He's played the last two years with the Salt Lake City Bees, though he missed almost half the 2013 season due to various injuries.
He's now a free agent. If he plays further, he's going to have to play first base (no DH). His batting ratings are still decent (13/11/9/14/12 -- out of 20).
