Horton had a locker in the Citi Field visitors clubhouse but was considered a member of the taxi squad Friday.

Horton reached the majors thanks to a collaborative process that began during spring training in Arizona: "He's going to impact this team."

Per Tommy Birch of The Des Moines Register, pitcher Cade Horton is expected to join the Cubs for their series against the New York Mets on the road this weekend. Horton, 23, is the No. 2 player in Chicago's farm system, per MLB.com.
