The Texas Rangers reached the 40-man roster limit and protected four players from the Rule 5 draft with several moves Thursday night.

The team added right-handed pitchers Luke Jackson and Jerad Eickhoff, infielder Hanser Alberto and catcher Jorge Alfaro to the 40-man roster, protecting them from Rule 5 draft.

To make room for the players, the Rangers designated outfielder/first baseman Jim Adduci for assignment and traded outfielder Daniel Robertson to the Los Angeles Angels for cash or a player to be named later.

The club also placed pitchers Miles Mikolas and Aaron Poreda on unconditional-release waivers, allowing each to play for the Yomiuri Giants of the Japanese League.

The Rangers will receive cash for this move.

In Robertson, 29, the Angels are getting a corner outfielder who hit .271/.333/.333 in 70 games 2014. The Rangers considered him as a possible No. 4 outfielder, but with the team needing to get to the 40-man roster limit, it was best to trade him.

Of the prospects moved to the 40-man roster, Jackson has a possibility of making the roster at some point during the 2015 season.
