According to Marc Topkin, Shawn Tolleson underwent Tommy John Surgery on Wednesday, so he’ll be out for the rest of the 2017 season and probably won’t be ready until September of next year.
The Tampa Bay Rays signed Tolleson back in January, with the expectation that he could be decent late inning arm to bring into high leverage situations. However, he would only pitch in five games for the Rays during spring training and ultimately was placed on the 60-day DL to begin the season.
Tolleson began his career with the Los Angeles Dodgers after being taken in the 30th round of the 2010 draft. He rose through the system fairly quickly and pitched in 40 games for the Dodgers in 2012. The Dodgers waived him in 2013, allowing the Texas Rangers to swoop him and claim him.
While with the Rangers, Tolleson put up so-so numbers in 2014 and then had a career year in 2015 in which he actually received some Cy Young award votes (placing 10th). Unfortunately, injuries crept in the following season and he has been plagued with trips to the DL ever since.
Tolleson will become a free agent this off-season, but I wouldn’t be surprised to see the Rays pick him back up and rehab him through the Tommy John Surgery as they have done now with several other pitchers.
