ARLINGTON -- Reliever Mike Adams, who can be a free agent after the World Series, will undergo surgery for thoracic outlet syndrome next Thursday in Dallas.
The surgery will be performed by Dr. Greg Pearl.
Thoracic outlet syndrome is a condition in which a rib bone presses against a nerve, causing pain and numbness in the arm. Adams was diagnosed with it late in the season and did not pitch after Sept. 27.
The right-hander is expected to need a full offseason of rehabilitation but is expected to be ready for Spring Training.
Adams finished the season 5-3 with a 3.27 ERA. He was 2-0 with a 7.56 ERA in nine games in September. He has a 1.98 ERA over the past five seasons, third lowest for any reliever in the Major Leagues with at least 153 innings pitched.
In addition, pitcher Matt Harrison underwent Lasik surgery on Thursday and catcher Mike Napoli will have a similar procedure next week. Napoli is also a free agent after the World Series.
