Dodgers' Joe Kelly reveals he underwent shoulder surgery last November

Los Angeles Dodgers right-hander Joe Kelly hasn't pitched since the World Series, and now we know why. 

Kelly revealed to WEEI's Rob Bradford that his shoulder hasn't felt good since the end of 2019, and he underwent shoulder surgery last November to deal with the issue. Kelly said:

"We found some cysts. My shoulder hasn't been good since the end of 2019. But during my suspension after the thing with the (Houston) Astros my arm was super weak. If I was laying on a table I couldn't lift my arm past gravity. They asked me how long it was going on for and I told them forever. I couldn't sleep at night and it felt like fire ants were eating my arm from the inside-out."

Doctors found a "massive" growing cyst on one of Kelly's nerves, which limited him to using 50% of the muscles in his shoulder.

In 12 games last season, Kelly registered a 1.80 ERA, 1.500 WHIP and nine strikeouts in 10 innings. He allowed just one earned run in 3 2/3 playoff innings. 

Kelly said he's hopeful he'll return to the Dodgers' bullpen soon.

The 32-year-old is in the final year of his three-year, $25 million deal and will be a free agent at the end of the 2021 campaign.
