Texas Rangers relief pitcher Matt Bush underwent surgery earlier this month, per the beat guys on Twitter. Dr. James Andrew did the surgery, which was an arthroscopic repair of the AC joint in Bush’s right shoulder, on October 19.
All the indications are that Bush should be ready to go for spring training.
This isn’t exactly surprising — there were reports all year about Bush dealing with shoulder issues which limited his availability, and it could help explain why he went from a 2.48 ERA/2.74 FIP in 2016 to a 3.78 ERA/4.00 FIP in 2017. Bush fanned batters at a higher rate in 2017 than in 2016, but walked more as well, and saw his HR rate double.
Hopefully Bush is fully healthy for 2018, and is back to being the guy who was such a huge asset in the pen his rookie year.
