I look at his history from last year, and the teams he faced +innings. Has to be injury related.
On July 11th the Sox shut him down for 11 Days.
Came back on July 22 and faced Detroit, went 6 innings did OK.
Then he went right back on regular turn then, it started.
Came back on July 27th faced the Twins, went 6 innings did good, but Sox shut him down for another 2 weeks.
Aug. 12th came back and went 5 innings, 1 hit ball against the O's.
Then shut down for 30 days.
Sept. 11th 1 inning Toronto
Sept. 16 against the Mets went 3 innings, trying to build the shoulder.
Sept. 21 against Cleveland went 3.1 innings.
Sept. 26 against O's went 4.2 innings, and got hit pretty hard.
From July 27th to Sept 26th, pitched a total of 23 innings.
Throw out that 1 inning that he pitched to win it, Sale had a 4.40 ERA, in the Play-offs last year.
The last 3 Months wouldn't you have a little concern that something might have gotten by the Red Sox Doctors.
It has continued, and Sale is the last guy who will say something especially after signing good extension. Not that he's a bad person trying to get over on the Sox. The guy will go out there with no arm.
I think something got by our Doctors. I would get 2nd opinion. Tears happen that you don't see.
3 Month Shut-Down then whole Off Season shut down, and he has declined.
Has to be injury, too good of a Pitcher for too long, for this to suddenly happen.
