The Cardinals have designated Ruben Tejada for assignment in order to make room on their roster Matt Carpenter. Tejada, who was with the Mets from 2010 to 2015, was cut by the Mets during spring training despite being tendered a contract earlier in the offseason. The Cardinals then signed him to a one-year deal to replace their injured shortstop Jhonny Peralta.
Shortly after that, Tejada himself was injured, leading to Jedd Gyorko starting at short on Opening Day for St. Louis. With Gyorko disappointing, Aledmys Diaz took over, and he's played like an All-Star, as he currently sports a .918 OPS on the season. With Peralta now playing in rehab games, Tejada's spot on the big-league roster was already tenuous.
Tejada was the Mets' starting shortstop in the first two games of the NLDS last year but was famously injured on a takeout slide from Dodgers by Chase Utley. The slide led to a rule change around takeout slides and folk hero status for Tejada, who received a standing ovation at Citi Field for Game 3.
