Tough call, and I don't have all the info Cora has, but with the day off on May 11th, pitching Bello would still give him an extra day off, so in a bubble, I'd go with Bello and give Pivetta some extra-extra rest.
Tomorrow? It might be a good idea to break paxton in slowly by giving him an extra day of rest, which he would not get by pitching, tomorrow. (With Thursday off, he'd get 2 extra days.)
I might go...
5/16 Bello (+1 day rest)
5/17 Pivetta (+3 days might be what he needs)
Day off
5/19 Paxton (+2) @SDP
5/20 Sale (+2) @SDP
5/21 Kluber (+2) @SDP (I might give Kluber a day or more off)
5/22 Bello (+1) @LAA (maybe pitch him on the 21st)
5/23 Pivetta (+1) @LAA (or maybe Kluber here, if he pitched well in his previous start)
5/24 Paxton (no extra rest) @LAA
OFF
5/26 Sale (+1) @AZ
5/27 Whitlock or Crawford? (Or, Bello over Kluber)@AZ
5/28 ??? It's getting too far out@AZ
OFF
Home for 3 v CIN then 4 v TBR
When you say it's gonna happen now
When exactly do you mean?
FWIW, the Mariners are ranked 15th in MLB in runs scored and 25th in team OPS.
Thanks everyone for a good discussion. I'm afraid the actual game could be painful.
