The Rangers have made an assortment of moves today with their minor league rosters, with the most noteworthy being the promotion of first baseman Ronald Guzman to high-A.

Guzman, 20, started the year at low-A Hickory, where he had also spent the 2013 and 2014 seasons. 2014 was a disaster for Guzman, as he got dropped from the roster at one point for oversleeping and showing up late, while finishing the year with a .218/.283/.330 line in 492 plate appearances.

This year has been much better for Guzman so far, as he is sporting a .309/.346/.433 line in 104 plate appearances, with 6 walks against 15 Ks. He will presumably be the everyday first baseman for High Desert now.

Taking Guzman's place on the Hickory roster is fellow bonus baby Jairo Beras, who was activated from the disabled list.

Jefri Hernandez, a minor league free agent who suddenly started throwing in the mid-90s this year, has also been promoted to High Desert. He's taking the bullpen spot previously manned by lefthander Cody Ege, who has been promoted to AA Frisco.

Meanwhile, lefthanded reliever Martire Garcia, who got an invite to the major league camp this spring, has been released.
