Rangers designate Rich Harden, claim pitcher

We interrupt our coverage of the ALDS to say goodbye to disappointing starter Rich Harden.

The Rangers claimed right-handed pitcher Ryan Tucker off waivers from the Florida Marlins on Wednesday. To make room for Tucker on the 40-man roster, the Rangers designated Harden for assignement.

Harden was left off the postseason roster after going 5-5 with a 5.58 ERA in 20 games, including 18 starts. In December, the Rangers signed Harden to a one-year deal that guaranteed him $7.5 million for this season, and he started the year as the club's No. 2 starter.

The Rangers have 10 days to trade, release, or outright Harden to the minor leagues.

Tucker, 23, appeared in 13 games for the Marlins in 2008, going 2-3 with an 8.27 ERA, then missed most of the 2009 season because of knee and oblique injuries. In 2010, he went 0-5 with a 6.15 ERA in seven games for Triple-A New Orleans. He also played for Class A Jupiter and the Gulf Coast League Marlins this year.
