The seven-year, $175 million contract extension the Seattle Mariners were prepared to offer pitcher Felix Hernandez may have hit a snag.
According to a report from ESPN's Buster Olney, the Mariners have developed concern about the status of Hernandez's pitching elbow, and negotiations over the contract extension have hit a snag because of that.
CBS Sports' Jon Heyman reports in a tweet that the negotiations could take a little while to be complete:
Hernandez has pitched 1,620 innings in his eight-year career, all of which has been spent with the Mariners. Hernandez has made the All-Star game three out of the last four seasons and won the AL Cy Young award in 2010.
