UPDATE, 6:55:Ivan Rodriguez receied an epidural shot in his ailing oblique and will pause his rehab for three days as the shot takes effect, General Manager Mike Rizzo said. After Rodriguez took batting practice Saturday, Rodriguez “still felt something” in his right oblique, Rizzo said, and was given the shot to “expedite” his recovery.

Once the three days for the shot to take its course pass, likely on Wednesday, Rodriguez will begin swinging a bat again. If Nationals medical personnel clear him to play, then he will begin a rehab assignment. [END OF UPDATE]

Ivan Rodriguez reported to Hagerstown yesterday, taking batting practice in the hope he could catch Stephen Strasburg’s rehab start today. Those ambitions were dashed, though, when the Nationals did not permit him to play this afternoon.

Rather squatting behind home plate today, Rodriguez has left Hagerstown in order to resume his rehab from a strained right oblique muscle. Rodriguez has been pushing himself in order to make a fast return, but because oblique injuries require time and rest, Rodriguez’s efforts have been more of a hindrance than a boon to his recovery.

Rodriguez last played July 6, the day before he strained his oblique during batting practice. Friday, he visited Dr. Bill Meyers, the Philadelphia-based specialist who also operated on Ryan Zimmerman’s torn abdominal muscle earlier this year.

Rodriguez, 39, served as the Nationals’ backup catcher this season. He is 158 hits away from becoming the first catcher to reach 3,000, but his recent injury has become an obstacle to overcome on his way toward the milestone.
