Josh Guyer is a 18 year old right-handed pitcher from South Wales Australia that was signed by the Minnesota Twins in late July. It was a 7 year minor league contract and he is set to join the organization in Spring Training (and considering his age, he will probably go to extended Spring Training until short season ball starts and join one of those teams). I watched his outing against New Zealand online (which you can watch yourself here) to get a look at the new Twin.
Guyer’s delivery contains nothing that is over the top, but there were a couple of things that I found a little strange. He doesn’t seem that he gets the best extension despite having decent height at 6 feet 2 inches (or 188 centimeters). Currently, he is already 185 pounds (84 Kilograms), so while he may add some weight, it won’t be much. He seems to have a slight hitch or hesitation in the middle of it, but I don’t think it is a big deal either in a positive way (deception) or a negative way (hard to repeat).
Guyer is known for his fastball (a “hard thrower“) and true to expectations, he was pretty fastball heavy in his outing. Especially early, it was staying mostly high, and he had pretty good command of it. It didn’t seem like it had great “life” but the velocity looked pretty good (though not eye popping or anything) and he was getting a lot of late whiffs (of course the competition he was facing was quite inferior). He did show the ability to move it a little bit inside (didn’t quite look like a cutter) and low to lefties. He could really become quite an effective ground-ball pitcher if he does consistently and it seemed like a legitimate sinker at times. He actually got his best swings and misses with the low fastball against right-handers. The only problem was that when he missed over the plate, it was when he was trying to throw low, not high.
Guyer also showed a slow and somewhat loopy curve (it is probably not quite 12-6 and not the traditional slow curve that you might see from Jered Weaver or Yu Darvish. However this may be what it eventually develops into as it certainly is not a “hard curve” and he threw a couple that were slower and more loopy than others) that he can throw for strikes and near the zone. I would like to see him get it down more (which he did a few times), but at age 18, it is a pretty good curve.
Overall, Guyer looks to me like a pitchability guy whose success will depend greatly on how his third pitch develops (I didn’t really see one other than one curveball that looked sort of like a slider) and the effectiveness of his fastball (like most pitchers). He is really advanced for an 18 year old pitcher, but the lack of dominant stuff will limit his ceiling.
