Worth noting

• Rangers first baseman Prince Fielder turned 30 on Friday.

• With infielders Rougned Odor and Luis Sardinas, the Rangers are the only team in the Major Leagues with two players who were 20 years old when they made their season debut. The Rangers haven't had two players under 21 on their Major League roster at the same time since 1991 with pitcher Hector Fajardo and catcher Ivan Rodriguez. The last time the Rangers had two position players under 20 on the roster was in 1989, when Juan Gonzalez and Dean Palmer -- both 19 years old -- were September callups.

• Odor was the ninth rookie used by the Rangers this season. The White Sox have used 10, while the Angels and the Yankees also have used nine.

• Infielder Michael De Leon, 17, whom the Rangers signed out of the Dominican Republic last July, has been transferred from extended spring workouts to Double-A Frisco. He was ranked by MLB.com as the 27th-best international signing last year. Outfielder Jamie Jarmon was also added to the Frisco roster, while catcher Brett Teschner was transferred from Triple-A Round Rock to extended spring.
