Ryan Dempster was among the best pitchers in all of baseball earlier this season, posting a 2.25 ERA over 16 starts during his time with the Cubs, although that resulted in just a 5-5 record.
Among the most sought-after players on the trade market, Dempster wound up in Texas on a Rangers team that badly needed to add some depth to their starting rotation.
With Colby Lewis and Neftali Feliz out for the season, Alexi Ogando in the bullpen and Derek Holland pitching well below expectations, the rotation has been a mess to say the least, and Matt Harrison and Yu Darvish have been the team's only reliable arms.
While Dempster appeared to be the answer, he has struggled mightily in his four starts with Texas, posting a 6.04 ERA on his way to a 2-1 record.
The 35-year-old is in the final year of a four-year, $52-million contract, and he's pitching for one last big deal. He'll need to regain his National League form if he wants to cash in, though.
