The biggest first base free agent is former Kansas City Royals, Eric Hosmer. He would be the biggest splash the Rockies could make in free agency, however it would come at a major cost (almost assuredly over $20 million a year for at least seven years).
I’m not sure if that’s a move the Rockies want to make, considering they gave Ian Desmond (who is supposed to be their starting first baseman) a five-year $70 million contract. Desmond hasn’t played to expectations and that is why first base is such a high priority for the Rockies.
So without spending a ton of money, there are some other options the Rockies can turn too. Logan Morrison is one of the younger first base free agents. Last year he played for the Tampa Bay Rays and hit .246 and has very good power, hitting 38 home runs.
Another possible first baseman the Rockies could go after is Yonder Alonso. Alonso played first base for the Oakland A’s and the Seattle Mariners last season. He hit .266 with 28 home runs.
Among the available first base free agents, Morrison and Alonso are second and fourth in WAR, respectively.
The question remains if the Rockies should risk signing a first baseman, when they already have a lot of money at the position in Ian Desmond. This isn’t an easy decision, because it all comes down to how much trust the Rockies have in Desmond to perform.
