Although Paco Rodriguez was seeing some progress in rehab, it was not enough.

The 24-year-old left was examined Thursday by Dr. Neal ElAttrache, who recommended an arthroscopy to remove loose bodies in the back of Rodriguez’s elbow. Surgery will be performed July 2, with Rodriguez expected to be sidelined for 8–10 weeks. That figures to put Rodriguez out of action at least until rosters expand in September.

A Dodger second-round draft pick in 2012, Rodriguez became the first from that entire draft to reach the Major Leagues, and from in 61 innings (87 games) 2012–13, he had a 2.21 ERA, 0.92 WHIP and 10.2 strikeouts per nine innings.

Rodriguez has thrown 24 1/3 big-league innings since, with a 3.33 ERA, 1.19 WHIP and 8.9 K/9. He most recently pitched for the Dodgers on May 29.
