The Chicago Cubs top overall prospect got his call to the League on Tuesday. Slotted as the Club's starting center fielder, the rookie's fielding capacity was put to the test, using his elite speed to make two outstanding plays to save a couple hits in the first and sixth innings. With runners on the corners in the second frame, the 21-year-old California native slapped a pitch to second base to cash in the man at third base to record his first big-league RBI.
