Masterson, 30, signed a one-year, $9.5 million contract with the Red Sox last off-season, but was not able to fully bounce back from his injury-stricken 2014 season or embrace his new role as a reliever.
This season, Masterson posted a 4–2 record with a 5.55 ERA in 17 appearances, nine of which were starts.
Boston has 10 days to decide whether they will trade, release or put Masterson on waivers. Masterson has said he does not want to retire yet.
“It really didn’t work out as well as we would have hoped this year,” Masterson told The Boston Globe. “I’m grateful for it. It’s that time. It’s a time when they’re bringing up some arms. They want to see some guys pitch some innings. So I’m going home for a little bit.”
The Red Sox are in last place in the AL East with a 50–62 record, 12 games behind the first-place Yankees.
