Some assorted prospect notes:
Alex Meyer of the Hagerstown Suns has a 95-97 MPH (touched 98 MPH in the Futures game as I watched his start before the Futures game and the Futures game) fastball. It has iffy command and he mixes it with a pretty good looking slider at 87 MPH
Cutter Dysktra on the Suns (the Nationals A affiliate) is listed as a 3rd baseman, but played 2nd when I saw him. He made a very good play defensively. Offensively, his long stint in A + last year was horrible, but he has been better (at least as far as K/BB is concerned) in the lower level. Matt Skole leads the league in walks and homers. He has an uppercut type swing, and a fly-ball hitter type swing.
The Tri-City Dust Devils (Colorado Rockies A-) closer Seth Willoughby is a skinny right hander with some swing and miss stuff. He has a good looking straight fastball, along with a moving fastball, and a curveball he can throw for strikes. At this point, he has thrown just 9 innings so it is hard to draw any conclusions, but it has been going well for him.
Drew Bowlin of the San Jose Giants is a little too old for the level and has just a 90 MPH fastball as a righty reliever. He has struggled so far this year, with a lot of strikeouts, but too many walks and a high ERA.
Richard Castillo of the AA Springfield Cardinals has a weird arm angle as a right-handed starter. He is pretty short and it doesn't look like he throws very hard. He has a soft moving fastball that tails low and in to righties. This is definitely his feature pitch and he was getting quite a bit of grounders.
Staten Island Yankees:
Saxton Butler is a big first baseman, so it is hard to get excited about him, but he has some really good pull power. He has a good looking swing and can go the other way with authority too.
Fu-Lin Kuo has a good approach and good long at-bats. He has a really good looking contact tool but nothing to suggest he will hit for much power.
Santos Rodriguez is a tall (6-5) lanky (180 pounds) left handed reliever for the Birmingham Barons (the AA of the White Sox). He hits 94-96 MPH on the gun, but even with his frame, at 24 he probably won't gain anymore velocity. He has been a fly-ball pitcher for a lot of his career with some pretty good K ratios (with perhaps too many walks).
Ryan Acosta of the Dodgers system (Rancho Cucamonga Quakes) has a curveball that he can throw for strikes. Despite an inconsistent delivery, he can throw 91-94 MPH as a right handed reliever. Acosta also has a changeup that he throws a lot. It has some break, but he can't really throw it for strikes. This didn't stop him from having confidence in it. This probably didn't help his control problems. He has sort of a starter's repertoire if he can gain command. It looks like he can miss bats.
Peter Hissey of the Portland Sea Dogs (Red Sox organization) is a lefty with a weak uppercut swing. His line drive rate is above league average, but his ISO is well below league average. He is an efficient base stealer but doesn't walk a ton.
Michael Foltynewicz is a former 1st round pick by the Astros currently playing for the Lexington Legends. He has a 94-97 MPH fastball, with pretty good control/command. He doesn't really have a great breaking pitch but has a decent curve that he can throw for strikes. The fastball is his best pitch, as he can locate it low or high. That pitch is why he was a first round pick. He gets some whiffs but doesn't appear to be a real strikeout pitcher (which matches with his numbers).
Mike Kvasnicka switch hitting catcher with a huge swing. He whiffs a lot and couldn't catch up to a plus fastball. Over the last two years, a 197 game period at Lexington, he is slugging just .368.
