Frasso's AAA debut:
Sat pretty much 92-94mph. Threw 10 pitches over 95mph and topped out at 97.
Looking at the pitch by pitch tracker, his velocity dropped after about ~35 pitches. His fastball was mainly averaging 92-93 from pitch ~#35-80.
Another thing: he had just 5 whiffs on a total of 80 pitches. His fastball in particular only had 1 whiff on 51 pitches.
His overall line in the start looks good, but the stuff is down and really wasn't impressive by MLB standards. And therein lies the concern over his future profile: is his stuff ever going to hold up over a normal starter workload? He's at ~80 IP on the season which is a career high, but if he's already getting "tired" in an 80-pitch outing then he isn't doing much to squash the reliever vibes. Like someone mentioned above, he was 97-100 mph in outings prior to us trading him, so an outing wherein he's mainly throwing 92 mph is way down.
Mitch White in his most recent AAA start: 95 mph average on his fastball with 5 whiffs on 36 pitches. Not making any sort of statement, but Frasso's actual stuff is worth monitoring.
