CC Sabathia has just one piece of advice for his friend Robinson Cano as the Yankees second baseman navigates free-agent waters for the first time. “Stay here,” Sabathia said Friday. “I’ve played with him five years now and I think he’s the best second baseman in the game. Obviously he is one of my dear friends, so we’ll have to wait and see what happens.” The ace lefty said he didn’t enjoy free agency five years ago, when he departed the Indians for a $161 million contract from the Yankees — the uncertainty surrounding the uprooting his young family was unappealing, he said — and hopes Cano has more fun with the process than he did. Cano could receive a $200 million deal and remains the focal point of what likely will be a busy offseason for the Yankees, who missed the playoffs for only the second time in 19 years. Sabathia, speaking at the Luxe Lounge at Lucky Strike in Manhattan to promote a scavenger hunt through Central Park on Saturday to benefit his PitCCh in Foundation, said he’s onboard if the Yankees want him to recruit free agents this offseason. “I’m down for recruiting,” he said. “I want to win. It’s hard to watch the Red Sox win the World Series this year, and you want to be in that spot, so whatever you’ve got to do to get the guys come play is what you’ve got to do.” Andy Pettitte’s retirement has left a gaping hole in the Yankees’ rotation, and Sabathia has another native Texan in mind to replace him.
