I was happy to see Beachy's velocity up again last night through four innings. But I noticed it started to fade in the 5th and more in the 6th. He had something like three straight fastballs of only 85 mph in the 6th. But through 4 innings he hit 93 mph a few times and had no issues hitting 92 mph quite a bit as needed.
This suggests to me that after the 5th he was a bit tired (and should've been pulled earlier).
