Few different routes they could go for an upgrade.
They need another SP, I think everyone agrees on that.
Two obvious position players they can upgrade on are Gallo and IKF. Gallo they would probably flip for spare parts, but IKF has always best suited for a super utility role. Find someone that can play a legit SS, move IKF to the bench, and cut ties with Marwin (even though he’s been pretty good).
I would be fine with IKF’s zero offense if he was playing good defense. Metrics and eye test have been saying he’s below average the entire year. Possibly in the bottom 1/3 of shortstops.
