Courtesy of MLB Tonight. They broke down why Latos was pitching better as of late in his past 2 starts (18 IP, 2 ER).
They said it was because of how frequent he has been using his slider, and how his slider is very deceptive, and how it's considered as an A+ pitch
This is how they broke it down:
First 14 G Last 2 G
F 58% 48%
S 26% 46%*
O 16% 6%
They said 25 outs (out of 54 outs from his last 2 games) have been recorded via the slider.
So some food for thought.
