If the Yankees wish to keep soon-to-be-free-agent second baseman Robinson Cano in pinstripes, it looks like it won't come cheap.

Multiple reports – including one from ESPN's Buster Olney – have Cano's salary demands at a 10-year deal worth a staggering $305 million.

The numbers may seem staggering, but, according to ESPN.com the figures are not unprecedented in Major League Baseball nor even for the Yankees.

The $305 million total is exactly the amount Yankees third baseman Alex Rodriguez would earn over the duration of his current deal, were he to hit all his built-in incentives. Cano has 27 home runs and 106 runs batted-in for the Yankees in 2013. The 30-year-old has racked up 204 home runs and 821 RBI with a .309 career batting average in 1,371 career games with the Yankees.

He has been selected to five All-Star Games over his nine seasons in The Bronx, winning two Gold Glove Awards, four Silver Sluggers. He has helped the Yankees qualify for the playoffs in every season he's played save two (2008 and 2013), winning a 2009 World Series ring.

Cano has already become one of just 14 second basemen in Major League history to surpass the 200-home run plateau. He was originally signed by the Yankees as an amateur free agent out of the Dominican Republic as an 18-year-old in 2001.

He is currently in the final year of a six-year deal he signed with the Yankees worth a total of $57 million. Cano switched representation earlier this season, signing on with Roc Nation Sports – backed by hip hop artist Jay-Z. Prior to signing on with Roc Nation, Cano was represented by Scott Boras, the agent responsible for negotiating Rodriguez's record-breaking deal with the Yankees in late 2007.
