Clear is debatable? But your starting infield could theoretically be 1B Mountcastle/O'Hearn, 2B Westburg, SS Henderson, and 3B Mayo. The 1B and DH also gives Mayo some flexibility to get starts there. Under this scenario, Urias is my utility infielder and Mateo is backing up CF and SS but primarily used as a pinch runner and late defensive replacement.
The challenge then could then be finding a spot for Kjerstad.
Also have to consider that not every position player projected for the big league roster is guaranteed to be healthy on OD. So additional spots could open up.
