Heyman reports the Crew is interested in Benintendi, which makes all the sense in the world.
The Brewers (and other NL teams) have a big leg up on acquiring Benintendi from the Royals, as he is unvaccinated. That basically excludes any AL team from aggressively pursuing him, as any matchup with Toronto takes Benintendi off the roster. It's hard to see an AL team that expects a postseason berth to pay for a guy who might write himself off the roster in the first or second round of the postseason.
Benintendi is a free agent at the end of the season and has a 127 wRC+. And maybe most importantly, an OPS approaching .400. He'd be a huge addition to a Brewers lineup that is plenty deep with power but often struggles to drive in more than one runner at a time with that power.
