He’s mostly a fastball pitcher, ranging from 86 to 91 mph, but seems to pitch most comfortably and effectively at 89 mph. Unfortunately, that leaves just a 4-to-5 mph spread between his fastball and changeup. But Janssen employed a liberal amount of north-south movement on his heater to change the batters’ eyes and that was very effective, on Saturday at least. He mixed in the occasional curve (ranging 74 to 79 mph) — which he can throw for strikes, and a slider that ranged from 83 to 86 mph. I’d like to see Janssen lean more on off-speed stuff, especially his breaking ball. I believe that would really complement his fastball.
