Ángel Salazar and John Young.
St. Louis Cardinals Oquendo spent all of with the Cardinals' triple A affiliate the
Louisville Redbirds. With the Mets, Oquendo had only ever played

third and in the

double by
Ken Griffey in the nineteenth, and took the loss. With

errors (three) by a second baseman in a 150+ game season—the record has since been broken by
Plácido Polanco (2009) and
Darwin Barney (2012), who recorded only two errors in their respective seasons. In the first game of the season, Oquendo suffered a hamstring injury that sidelined him for most of the season. Oquendo spent three more seasons with the Cardinals as a
