Winningham is committed to Florida Gulf Coast University, but his loyalties might be flexible.
"Hopefully, I'll get drafted and get offered some good money," Winningham told the Ocala Star-Banner last summer. "If that doesn't happen, I'll go to Florida Gulf Coast for three years and try to do a good job there."
If he does do away with his commitment and sign with the Mets, the team will pick up a left-handed hitter who won't turn 19 until October, but is already 6-foot-2 and 230 pounds.
In addition to manning first for Trinity Catholic -- and helping the Celtics to a 19-9 record and a state championship -- during his high school season, Winngingham played for the Orlando Scorpions during the summer.
