I did like that today, at least, Pagan threw a lot of fastballs. And pretty well located, at that. IMO he's got enough fastball to do that, and his troubles often arise from breaking balls poorly located, or falling behind with breaking stuff and being forced into "get it over" fastballs.
I nice slider down and away, ahead in the count, is fine.
I'd like to see Jax throw more fastballs, too.
