I'm following along on game-day, so I don't how accurate it is all the time, but hasn't Rosario swung at a number of pitches well out of the strike-zone today?
The problem with Royce is that he has not shown any improvement. Since June 1st is hitting .240/.235/.280. In 51 PAs he has not drawn a single walk and hit only a pair of doubles. In terms of OPS, he's actually regressed throughout the year.
Rooker seems to be turning the corner at AAA... Look out! Including tonight's game, he's had an even 50 PA since June 1st. In those 50 PA he's struck out only 12 times, drawn 12 walks (24%), and hit .429/.540/.629!
