Gary Sheffield made plenty of money during his career, but the slugger believes the value of playing in a stacked lineup might outweigh the almighty dollar.

That’s why Sheffield believes Robinson Cano could ultimately regret his decision to bolt the Bronx for Seattle, where he signed with the Mariners for 10 years and $240 million.

“When you leave New York, you’re gonna feel it,” Sheffield said Wednesday on MLB Network. “Just ask guys like Johnny Damon and all these guys that had names and went somewhere else, you didn’t hear anything about them. And I think that Cano is a good enough player that you’ll hear about him, but being in a lineup like that — he hasn’t tasted that kind of food yet.

“You’ve gotta be the first batter and the second batter all the way through the ninth batter and when you have to go up there every day and face that, you start to realize that money ain’t everything.”

Sheffield was a teammate of Cano’s in 2005-06, the first two years of the second baseman’s career. Now an agent, Sheffield said he would have done his best to keep Cano in pinstripes had he been representing him this winter.

“I would’ve tried to bridge the gap,” Sheffield said. “I would’ve tried to do everything possible to make that (Yankees) contract work.”
