If I was picking players from the SOX for the All-Star game at this point I would go with Betts, JD, Sale, and Kimbrel. Because Kelly isn't a closer, he probably won't be chosen, although, at this point in the season, he deserves to be.
Barnes was throwing 98 so I doubt there's any physical problem. Like someone earlier mentioned, 98 with no movement has a name in baseball. It's called batting practice.
It's always a quagmire. Did Kelly tell Cora he wouldn't be able to pitch tonight? Or did Cora make that decision. Cora's gonna rest these players right into a WC situation.
What you say is true, but there are situations where it comes in handy. Players like Bradley should know how to bunt because that may be the few times he can help the team offensively.
