Alvarez (elbow) was activated from the 10-day disabled list Tuesday, Jeff Wilson of the Fort Worth Star-Telegram reports.
Alvarez had been sidelined for a little over a week with the elbow issue and felt fine during a 26-pitch bullpen session over the weekend, which was good enough for the Rangers to bring him back without sending him out on a rehab assignment. The southpaw has submitted a 3.48 ERA and 12 strikeouts over 10.1 innings this season and is expected to settle back into a role in middle relief, mostly acting as a lefty specialist.
