Ross (elbow) threw a 30-pitch bullpen session Friday, Jesse Dougherty of The Washington Post reports.

EDGE Analysis

Ross was expected to require 6-to-8 weeks to recover after undergoing a procedure to remove a bone spur from his elbow in March, but he won't be eligible to return to major-league game action until at least early June since he's on the 60-day IL. While the right-hander still needs to work on building up, he appears to be trending in the right direction.
