The Giants signed Matt Chapman to a six-year contract late Wednesday night. It replaces the last two year of his current contract and runs through his age 37 season. The deal is worth $151 million.

Baseball Reference and FanGraphs differ greatly on Chapman’s WAR. For 2022-2024, BR has him at 13 WAR. FanGraphs put him at 11.4 WAR. Using BR WAR, I would estimate Chapman at producing 20.3 WAR over the life of the contract, 17.8 WAR according to Fangraphs.

It always seemed to me that FanGraphs WAR is more predictive, while BR is more awards driven; what the player should have done than what he actually did. It could be that FG in this case is consistently underestimating Chapman.

That would translate to the Giants paying him $7.4 per million per WAR based on BR, $8.5 million per WAR based on FanGraphs. Either one strikes me as a bargain, indicating the Giants built in a discount in case Chapman’s decline comes back.
