"CarGo at first base is something we've talked about introducing a little bit this spring, but it's more of a potential longterm outlook," Weiss said.
Before the Rockies dealt outfielder Corey Dickerson to the Rays in a trade that brought them lefty reliever Jake McGee, there was speculation that Dickerson or Gonzalez could play some first base. Weiss was asked on multiple occasions if Dickerson could be moved to first base, but he always answered with a decisive, "No."
"We're not really looking to circulate him at first base -- just starting to introduce it in a practice setting," Weiss said.
