When Mark Teixeira came to New York as a member of the 2008-09 Yankees' vaunted offseason free agent class, he was framed as a switch-hitting winner who could dominate equally from both sides. After his post-retirement disappearance and prominent return to the public sphere on Thursday morning, it's pretty clear he's always preferred one side to the other.
Teixeira retired after the 2016 season, tanking the Red Sox postseason run preemptively with a hilarious walk-off grand slam off Joe Kelly. Though he battled injuries during the latter part of his Yankees career, he essentially delivered on every promise he made when he arrived.
