Rodriguez, who underwent the procedure in March, is progressing on schedule. He's throwing long toss and, once out to 120 feet in a few weeks, will pitch from flat ground before graduating to a mound. Barring any setbacks, he hopes to be throwing bullpen sessions by October.
Rodriguez said he'd be up to pitching in the Arizona Fall League or with a winter ball team if allowed to do so. Either way, he expects to be at 100 percent by Spring Training.
The 28-year-old right-hander compiled a 10.13 ERA in four Spring Training games with the A's before learning that his ulnar collateral ligament was torn. Last year, he appeared in 71 games for Houston, compiling a 5.38 ERA and 78 strikeouts in 70 1/3 innings.
