I've noticed Taylor has retooled his swing a bit since I last saw him... gets his bat in a load position a lot quicker. That's good to see.
Taylor's pitch recognition is still subpar, but he seems to have improved the latter issues thanks to an adjustment in his stride. In video I watched of Taylor in June 2013, he employed a toe tap while getting ready to swing. At first, his left foot would lift slightly and he would bring it down on its toes, then he'd lunge forward from there, returning the left foot flat on the ground.
As the split-screen photo shows below, that's no longer the case. Both photos were screen grabbed as the ball left the pitcher's hand.
On the left, from 2013, Taylor is in the middle of his toe tap; on the right, from 2014, his left leg is raised a few inches off the ground.

The leg lift appears to have made it easier for Taylor to go from deciding to swing to actually swinging. In watching a few 2013 at-bats, it appears Taylor was often late bringing the bat to the hitting zone and would be forced to hurry his swing to catch up. When he did this, he had a tendency to jerk his head while trying to whip the barrel into the zone, and that kind of head movement can make it difficult to make solid contact.
