Jurickson Profar up to majors

Jurickson Profar, the No. 1 prospect in baseball according to ESPN.com's Keith Law, will join the Texas Rangers on Saturday, the first day rosters can expand to 40 players.

The 19-year-old Profar will give the Rangers an additional infielder off the bench.

The Rangers also announced a slew of roster moves that go into effect on Saturday, which include placing left-handed pitcher Robbie Ross on the disabled list with a left forearm strain.

Profar spent the entire season at Double-A Frisco, hitting .281 with 14 homers and 62 RBIs. He scored 76 runs in 126 games and played mainly shortstop, though he did appear in 25 games at second base, five as the designated hitter and one at third base.

He had 47 extra-base hits, the most by any Double-A infielder, and has hit .294 (134 for 456) since opening the season 2 for 26. His 50-game on-base streak that lasted nearly two months early in the season is the longest by any minor league player this year.

Ross is 6-0 with a 1.78 ERA in 52 bullpen outings for the Rangers this season, his first in the big leagues. He had the fourth-lowest ERA among AL relievers entering Friday.

The Rangers also plan to add to the roster on Saturday: OF Leonys Martin, LHP Martin Perez, RHP Tanner Scheppers, INF/OF Brandon Snyder and RHP Yoshinori Tateyama.
