Alfonzo, 36, is a member of the Atlantic League's Newark Bears and hopes to catch on with a major-league team again at some point.
"I feel pretty good," Alfonzo said. "I'll try to get back and see what happens. I told my wife maybe in a couple more years, when I'm 38, I'll retire. But if there's any teams out there that believe I can help them, I'll be ready."
As for this year, Alfonzo is keeping his options open. When asked what position he'll be playing for the Bears, he replied: "Third, second, shortstop and first."
