I'm not sure. I've been really po'd at Breslow this season with his focus on pitching and ignorance about hitting, which stinks.
That said, Breslow's payroll is 12th largest in MLB, well below all previous CBO's under John Henry. I think he went after pitching because that's what he knows best.
Also, two of his priciest bats, Yoshida, and Story, are leftovers from the CB era. Plus Anthony and Mayer and Campbell, all studs in the minors, are now struggling with MLB pitching. Abreu and Rafaela, both from CG era, look good. Contreras right now is better than Bregman was last year (especially after injury).
