Angels prospect RHP R.J. Alvarez has 14 strikeouts and is yet to allow an earned run through 9 1/3 innings out of the Double-A Arkansas bullpen.
Alvarez, 22, posted a 2.96 ERA and 79/29 strikeout-to-walk ratio in 48 2/3 innings last season at High-A Inland Empire, and he's now knocking on the door of the major leagues with his great start at Double-A. The right-hander has appeared in six games this season and recorded multiple strikeouts on five occasions. Alvarez has the potential to be a late-inning weapon for the Angels and should join the team's bullpen by midseason.
Rangers acquired OF Dan Robertson from the Padres for cash considerations; purchased his contract from Triple-A Round Rock.
Robertson, 28, has never played in the majors and just began his third straight season at Triple-A for the Padres. He's a career .304/.381/.411 hitter on the farm, has good speed and can play all through outfield spots. He'll provide some depth with Shin-Soo Choo (ankle) banged up.
