The Rangers have claimed Ryan Tucker off waivers from the Marlins, according to Joe Capozzi of the Palm Beach Post (via Twitter). To make room on their roster for Tucker, Texas designated Rich Harden for assignment, tweets MLB Network Radio Executive Producer Brent S. Gambill.
Tucker, 23, was selected 34th overall by the Marlins in the supplemental round of the 2005 draft. Though Baseball America ranked him as Florida's sixth-best prospect prior to the season, the right-hander struggled in 32 minor league appearances this year, posting a 5.72 ERA over 67.2 innings. Tucker enjoyed his best season in 2008, when he was named the Marlins' minor league pitcher of the year and made 13 appearances for the big league club.
Harden, meanwhile, signed a one-year contract last winter which includes an $11MM mutual option for 2011. Considering the righty didn't even pitch well enough this year to crack the Rangers' ALDS roster, the team figures to have to pay the $1MM buyout.
