It was good to see Hjerpe only walk 2. Still a 4.5 BB/9 rate, but a little improvement that can hopefully improve.
The best thing that could happen to Hjerpe is if he could somehow follow Jordan Hicks out the door. Get somewhere where they would have him dial it back a couple ticks and use his repertoire, better control and actual pitching skill, at the expense of fewer Ks, to get batters out and be successful. All while putting less stress on his arm. Cardinals pitcher development seems to consist of ‘adding a few ticks’, which works great for throwing it past minor league hitters.
