The Oakland Athletics have announced that right-handed pitcher Andrew Triggs will undergo thoracic outlet surgery on Sept. 26.
Head trainer Nick Paparesta confirmed to the Examiner that Triggs is suffering from thoracic outlet syndrome, a group of disorders that occur when blood vessels or nerves in the space between the collarbone and the first rib are compressed.
Triggs, who was placed on the 60-day disabled list on July 13, will undergo the surgery, performed by Dr. Gregory Pearl from the Texas Vascular Associates in Dallas, Texas, on Sept. 26.
Whether or not the surgery will require resection of the first rib is unknown. The degree of the procedure will be determined once Triggs is on the table.
The 27-year old pitcher began the season in the A’s starting rotation, and went 3-1 with a 5.23 ERA in 41 1/3 innings with 43 strikeouts in nine starts. He was sent to the 10-day disabled list on May 18 with right arm nerve irritation, then transferred to the 60-day disabled list in July.
Oakland has endured a rash of pitching injuries this year, including four Tommy John procedures (Jharel Cotton, A.J. Puk, Kendall Graveman and Daniel Gossett). In total, 10 A’s starting pitchers have made visits to the disabled list: Triggs, Puk, Cotton, Graveman, Gossett, Paul Blackburn (strained right forearm; right elbow lateral epicondylitis), Trevor Cahill (right elbow impingement), Brett Anderson (left shoulder strain; strained right Achilles; strained left forearm), Daniel Mengden (sprained right foot) and Sean Manaea (left shoulder tendonitis).
Triggs made one rehab appearance with Stockton during the postseason on Sept. 5 vs. Visalia. This is the second season in a row that he has ended the year on the disabled list after suffering a strained left hip in 2017.
