Red Sox optioned RHP Jedixson Paez to Triple-A Worcester.
It was a rough first MLB start for Paez on Tuesday, allowing eight runs in 3 2/3 innings against the Mariners. He did throw 63 percent of his pitches for strikes, including 86 percent on his curve, and his changeup posted a 17 percent swinging strike rate against lefties, but his fastball locations were not good, and he simply doesn’t throw hard enough to get by without solid location. There’s a chance he gets another spot start this season to keep Boston’s regular starters fresh for the playoffs.
