Utility player, of which you need at least 1, if not 2. Hamilton has probably the inside lane over Gonzalez if David can finish the year in a consistent fashion at SS. There is a $2M club option on Refsnyder for 2025, and I bet they sign him up for that price.
Then you have the #2 catcher, currently McGuire , who will be in arb #3 I believe. So 1 bench slot left on a `13 man position player roster . Probably come down to Valdez vs Gonzalez.
Keep in mind there will be some other youngbloods looking to break through next Spring, Anthony, Teel (?), Mayer (?). Sorry Story and Gruesome Grissom will be back as well ( for a short while)
Yoshida kind clogs the Red Sox colon , ability wise and money wise, unless he starts hitting .350 OBP and .800 OPS for his $18M salary. My advice, carry Yoshi into the winter and see if a multiplayer deal pops up, be prepared to pay about $12M of his money, even if he hits well over last 3 months.
