Yogi Berra once famously said, "Baseball is 90 percent mental. The other half is physical."
His numbers might have been a little off, but the sentiment is spot on. Jurickson Profar certainly can attest to that.
The A's second baseman committed his seventh error of the season Monday night, leading to six unearned Red Sox runs, sending the A's to their fourth straight loss, 9-4.
Profar's seven errors are three more than any other second baseman in Major League Baseball this season. Even more troubling, six of the seven have been throwing errors and they haven't even been close.
