MLBTradeRumors has released their annual arbitration salary projections for the 2018-19 offseason. Their forecast has been pretty much spot-on over the years, allowing us to get an accurate early peak into the books of all 30 MLB clubs. Arbitration salaries are determined by a multitude of factors, including service time and performance. Teams can either negotiate with arbitration-eligible players to avoid arbitration altogether, take the negotiation to an arbitrator, trade the player, or non-tender the player, thus making them a free agent.
As for the Mariners, they’re in a really good spot with these projections. At the top are James Paxton and Álex Colomé.
