That is true. That is also whyI suspect the Reds will look to move him.
However, I don't think his salary will explode via arbitration because of the way the system is set up.
The average raise in arbitration is about $900M, with first year eligibles getting less than that. I would suspect catchers only get about half of that due to their generally lower salaries/stats and the lack of great young catchers to compare to between the 2 & 3 year service level. I'd be surprised if Larue exceeds $700M in arbitration, and I expect something in the $600M range.
Considering the new CBA boosted the minimum salary to $300M, $600M is still pretty darn cheap.
