That's going to be tough to pull off, though. Unless a team can pull of a deadline trade for a pitcher with two full years of control remaining, thereby benefiting his new team with (hopefully) three playoff runs and two full seasons, I haven't heard of many of those deals happening. Houston got Gerrit Cole with two controllable years remaining, and unless a team is really pinching pennies, there isn't much incentive for anyone to trade a pitcher with more than two arbitration years remaining.
It would definitely cost more, but the potential trade partner is adding prospects with more controllable years. For a team like the Marlins, that's got to be very appealing.
