Jay Bruce is going to be traded. That’s a near-certainty. He’s the only player on this year’s market to be (almost) traded not once, but twice by the team for which he still plays. The rumors have been persisting for more than a year now. Bruce is in the last guaranteed year of his contract, the Reds were never in contention, and he’s rebuilt his value with a great first half at the plate. Already, we’ve heard Bruce linked again to the Blue Jays, alongside the Indians, Nationals, Dodgers, and others. It will be an upset if he finishes the season wearing a Cincinnati uniform.
That much about Jay Bruce, we can be confident. We can be confident that he’s been a good hitter in the past, we can be confident that he’s been a good hitter in the present, and we can be confident that he’s likely to be moved within the next month. There exists an area of Bruce’s story that’s far more murky, though, and one’s perception of that area of Bruce’s game goes a long way towards one’s evaluation of Bruce. Despite a 120 wRC+ this season, Bruce has been worth 0.0 WAR, according to our calculations and 0.4 WAR by Baseball-Reference’s, and that’s all due to his defensive numbers.
The defensive numbers hate Jay Bruce this year. Ultimate Zone Rating calls him the season’s worst defensive right fielder, among 21 qualifiers. Defensive Runs Saved has him in a tie for last, with J.D. Martinez. Those negative marks stretch back a couple years now, but then you get recent tweets like this from Jeff Passan:
And quotes like this out of Buster Olney columns:
Bruce’s defensive metrics are not good, but some scouts believe that he’s better than those numbers indicate, and wonder if his skills are properly reflected in the stats — which some evaluators believe may be inexact.
And you begin to sense a divide on the evaluation of Bruce’s defensive ability. And it’s an important divide, because a Bruce with average-to-better defense is a useful player. A Bruce closer to what the defensive metrics suggest is a replacement-level designated hitter. Those two players fetch far different returns in a mid-season trade.
