He wasn't close to full speed. He was using choppy steps trying to get ready to time his jump.
Worth-lex only helps us with his D. He had another chance tonight and failed. From 14-16' he maybe had 1 ball go off his glove without catching it. This is the 3rd time he has had a ball go off his glove just since Aug 1. In addition to that, he dropped a flyout at the wall (and was given an error). Surprise surprise that was in the 9th. That game Mauer overcame that 2-base error, getting 3 outs in a row vs Twins.
In April, May, June, everyone said Worth-lex isn't do anything with his bat, but his D is still a big asset. And it was. But.....that ship has sailed now too
