Nationals outfielder Jayson Werth is undergoing shoulder surgery today, and the Washington Post is reporting that he will need two to three months of rehabilitation.

For the mathematically challenged, Opening Day (April 6) is two months and 28 days away.

Werth originally hurt his right shoulder — diagnosed as AC joint inflammation – in August, missed a week and needed a cortisone shot to relieve the pain. The shoulder joint inflammation affected Werth’s range of motion and forced him to adjust his swing to avoid the pain. Werth still hit .338 with six homers and 19 runs batted in the final six weeks of the regular season.

Werth explains:

“I’ve been dealing with this issue since I banged my shoulder on the fence in August, if you remember I received two cortisone shots during the season for this issue,” Werth said in an email to the Post. “There was hope that it would heal with time and treatment, I pretty much did everything legally possible to not have surgery but in the end surgery was the best course of action with the 2015 season and beyond in mind.”

Werth said the “major shoulder tissue” has not been harmed, nor the rotator cuff or labrum, which is a good sign. The AC joint procedure will be done with a scope, which is minimally invasive, and performed by Diane Dahm of the Mayo Clinic in Rochester, Minn.

“I am fully confident in her, her staff and her care during this procedure and expect a full recovery,” Werth said. “I will continue to work and play hard for my city, my teammates and all Nat fans with the hopes of bringing a title home to DC. I would like to thank everyone for there thoughts, prayers, and support as we work diligently through this process. Go Nats.”

The “Go Nats” is a nice touch, as is the “everything legally possible to not have surgery.”
