The Texas Rangers hold a 2014 club option on Joe Nathan, who hopes to renegotiate a long-term deal.
Texas has three days to either exercise Nathan's $9 million option for next season or cut him a check for $750,000 as a buyout.
If the club decides to exercise the option, Nathan has the right to void it thanks to finishing at least 55 games in 2013.
"I want at least two years," Nathan said. "The last couple of years, I think I've proven that I'm healthy. I think I've proven to lots of skeptics and critics that I can handle a two-year deal or maybe two and an option."
