Thursday Cup of Coffee, 4/13

Daily notes on prospects from lead prospect analyst Eric Longenhagen. Read previous installments here.

Foster Griffin, LHP, Kansas City (Profile)
Level: Hi-A   Age: 21   Org Rank: HM  Top 100: NR
Line: 6 IP, 3 H, 0 BB, 0 ER, 6 K

I saw Griffin sit 86-89 last year and get torched by a good Lynchburg lineup. He’s allowed one run and K’d 14 over 11 innings so far this year.

Joe Palumbo, LHP, Texas (Profile)
Level: Hi-A   Age: 22   Org Rank: 7  Top 100: NR
Line: 6 IP, 2 H, 0 BB, 10 K

Palumbo’s stuff has held since moving from the bullpen and into the rotation, sitting low to mid-90s with a plus curveball. Scouts wanted to see him work more efficiently and improve his changeup this year, and he has a mid-rotation ceiling if he can. The change need only progress to average if Palumbo is going to locate his curveball like this:

Magneuris Sierra, CF, St. Louis (Profile)
Level: Hi-A   Age: 21 Org Rank: 9 Top 100: NR
Line: 3-for-5, BB

Sierra has Gold Glove-caliber tools in center field but is also now riding a five-game hit streak, three of those games of the multi-hit variety.

Seranthony Dominguez, RHP, Philadelphia (Profile)
Level: Hi-A   Age: 22   Org Rank: 18  Top 100: NR
Line: 6 IP, 3 H, 0 BB, 1 ER, 10 K

The Phillies have a lot of young Latin American pitching and I spoke with a scout, when I wrote up the org, who liked Dominguez best among the ones he saw. Other scouts saw him struggle with control and thought the arm action fit best in the bullpen (and I wrote him up as a power reliever). He has walked one and K’d 14 over eight innings so far this year, has been 94-97 and up to at least 98 with the fastball, and missing bats with his breaking ball (the slider is ahead of an infrequently used curveball right now) and changeup while also locating the breaking ball for strikes in the zone.

Andy Beltre, RHP, Miami (Profile)
Level: Hi-A   Age: 23   Org Rank: HM  Top 100: NR
Line: 3 IP, 1 H, 4 K

Beltre has barely pitched since 2012 due to injury but threw hard last year, 94 plus with an above-average slider, and raised his arm slot. He went unpicked in last year’s Rule 5 draft but might move quickly, if he’s healthy, as a reliever.

“Foster Griffin” sounds like a 1980s Hollywood Squares celebrity panelist.

Of course, I HAVE been watching a lot of Foster Brooks on YouTube lately…
