Taylor Jordan undergoes second Tommy John procedure (updated)

Right-hander Taylor Jordan underwent Tommy John ulnar collateral ligament replacement surgery Thursday performed by Dr. James Andrews, the Nationals announced.

It is the second time Jordan has undergone the procedure. He first had the surgery in 2011 and returned in late 2012. Jordan was a ninth-round selection by the Nationals in 2009.

Nationals assistant general manager and vice president, player personnel Doug Harris said the club was careful in following Dr. Andrews' diagnosis before deciding to have Jordan undergo the procedure again.

"Dr. Andrews was thorough in his testing which led to this diagnosis and course of treatment," Harris said through text message. "Taylor worked diligently through this process in the past and will do the same once again. At this point the focus is on Taylor's rehab and together doing everything we can to help him return to competition in the future."

Jordan made his major league debut on June 29, 2013. He appeared in 18 games with 15 starts for the Nationals from 2013 to 2015.

His best run was 2013 when he went 1-3 with a 3.66 ERA in nine starts. He made five starts with the Nationals in 2014 and appeared in four games with one start last season.

Jordan made three starts with the Triple-A Syracuse Chiefs this season before being shut down. He was placed on the seven-day disabled list April 21. Jordan went 0-0 with a 1.72 ERA in 15 2/3 innings this season, his last start was April 19 at Lehigh Valley.

Jordan went 30-24 with a 3.15 ERA in 100 minor league games (93 starts) with 373 strikeouts in 489-plus innings, including three complete games and three shutouts.

This is an unfortunate setback for the 27-year-old Jordan, who was always considered a top 20 prospect with the Nationals. Jordan's rehab from the surgery begins immediately, and he will have the knowledge of the 2011 procedure to help him back again this time.
