It appears Yan has recovered from his knee injury, because he's back to being awesome.
Yan Gomes was the best catcher in the American League in 2014. He was the best catcher in the American League during the second half of 2013 too, after taking over the job midseason.
A sloppy slide by Detroit's Rajai Davis during the fifth game of this season injured Yan Gomes' right knee, causing him to miss six week, and upon his return to the lineup in late May, Gomes struggled for a while. On June 29 Gomes had his first 3-hit game of the season, and he had a good final couple weeks leading into the All-Star break, with as many extra0base hits in those 11 games as he'd had all season to that point.
