The Giants are said to want to extend star closer Sergio Romo, who's off to a big start, but any contract talks will very likely wait until the season's over.

The sides have agreed not to let talks disrupt the season, so assuming the Giants remain in contention they won't engage in discussions about any deals with the free-agent-eligible reliever until after the year. In the meantime, Romo is setting himself up for a decent-sized pay day with a terrific beginning in his walk year.

With incumbent teams holding options on other top closers Rafael Soriano ($14 million) and Huston Street ($7 million), Romo could be viewed as the top free-agent closer in his prime. The market will be far from bad, however, as no one's having a better year than Brewers closer Francisco Rodriguez, and other free-agent closers could include Jason Grilli, LaTroy Hawkins, Casey Janssen and Jim Johnson (and potentially, Soriano and Street, depending on their 2014 seasons).

The Giants have an excellent record of keeping their better players with long extensions, including deals for Buster Posey, Matt Cain, Hunter Pence, Tim Lincecum, Jeremy Affedlt, Javier Lopez and Angel Pagan. Pagan signed back after becoming a free agent, Lincecum re-signed days before he would have filed for free agency and Pence became a rare Giants player to sign during the season, when he agreed to a $90-million, five-year deal with a couple games left in the 2013 season, a rare year the Giants didn't contend.
