The Texas Rangers are planning to bring top pitching prospect Martin Perez back to the majors and give ace Yu Darvish an extra day of rest.
After Thursday's series-clinching 4-3 victory over Oakland, the Rangers said they would recall left-hander Perez from Triple-A Round Rock on Saturday to start that night against the St. Louis Cardinals.
Rookie right-hander Nick Tepesch (3-6), who had been listed as Saturday's starter, is being pushed back to series finale Sunday of the team's first trip to St. Louis since the 2011 World Series.
Darvish (7-3), the major league strikeout leader, had been scheduled to start Sunday night against Adam Wainwright (10-4). Darvish will instead pitch the series opener Tuesday at the New York Yankees.
