Winquest was designated for assignment by the Yankees after Thursday's 1-0 loss to the Athletics, Gary Phillips of the New York Daily News reports.
He is the odd man out with Luis Gil set to make his return to the major-league roster Friday. It does come as a bit of a surprise that Winquest lost his spot on the 40-man roster though, and he will now be subject to waivers. The right-hander made the Opening Day roster after joining the Yankees as a Rule 5 Draft pick in the offseason, but he never appeared in a game. If Winquest clears waivers, he'll be first offered back to the Cardinals, his original team, before he'll be eligible to remain with the Yankees' organization.
