The Rangers are expected to promote Jurickson Profar as rosters expand to 40 players on Saturday.

Keith Law of ESPN rates the infielder as the No. 1 prospect in baseball.

Profar hit .281 with 14 homers and 62 RBIs for Double A Frisco this season. He primarily played shortstop, but also saw some time at third, second and as a designated hitter.
