Yankees slugger Alex Rodriguez has dated a number of boldfaced names—Madonna, Cameron Diaz, Kate Hudson—but now he's in a new league: Billionaire Silicon Valley CEOs. Sources tell Page Six and People that A-Rod is dating Anne Wojcicki, head of genomics company and the ex-wife of Google co-founder Sergey Brin.

According to Page Six, "The couple was at Graydon Carter’s power player-packed pre-Super Bowl gathering in San Francisco, where they were pictured together. Rodriguez and Wojcicki were also last week spotted dining with friends at Bern’s Steak House in Tampa, Fla., where he was in town for spring training. A-Rod was also in the audience when Wojcicki, CEO and co-founder of genetic research firm 23andMe, spoke at a satellite event for the Annual Clinical Genetics Meeting in Tampa."

In a change of pace from exes Madonna, Diaz, Hudson and retired pro wrestler Torrie Wilson, not to mention ex-wife Cynthia Scurtis, Wojcicki is not a blonde. A source claims, "Alex and Anne are spending time together and have been on a few dates. It is very new. He finds her interesting, inspirational and very smart."

Both Wojcicki and Rodriguez have two children each from their previous marriages. Wojcicki reportedly received billions in her divorce from Brin; she apparently discovered that Brin and Google Glass marketing manager Amanda Rosenberg were having an affair after finding messages he sent Rosenberg. Wojcicki's sister Susan is the CEO of YouTube, BTW.

Of course, it's unclear what fans from opposing teams will do to taunt A-Rod if he's still dating Wojcicki well into the season—wave double helix models?
