Ynoa is third in the NYP in innings pitched, second in WHIP (0.84) and fifth in opponents' batting average (.196) and fifth in opponents' walk rate among starters (1.15 BB/9). For the year, he's 4-1 with a 2.45 ERA with 45 strikeouts against seven walks. I saw him at 90-92, touching 93 in his first start of the year, with the ability to spin a below average slider for a strike. That's plenty of stuff to succeed in the New York Penn League. He's just 19, and the Cyclones press release claims he's the "youngest starting pitcher in franchise history" so there's a little bit of projection left for him. I view him as a back-end type rotation guy if everything works out and his secondary offerings progress.
Mateo leads the New York Penn League with 67 strikeouts in 54.1 innings pitched, the fourth-most innings on the circuit. Among starters, Mateo has the second-highest strikeout rate (11.10 K/9) behind only teammat Rainy Lara and has the fourth-lowest walk rate (0.99 BB/9). Overall, he's 4-4 with a 2.82 ERA. I saw him at 90-95 over the course of 5.2 innings. He was mostly 92-92 with a slider that was 88-90. I, and other professionals behind home plate, had trouble even identifying the pitch. That's not a good sign. With inconsistent velocity, a full-effort delivery, and two potential plus pitches, I see a bullpen pitcher for Mateo if he ever reaches the big leagues.
Robles is fourth in the NYP in ERA (1.74) with a K/BB over 7 (44 K/6 BB) in 46.2 innings. Apparently, he was up to 94-95 in his last start and mixed in a changeup according to NY Penn League Report's Dave Gershman. Two facts that limit his ceiling significantly: he'll be 22 next week and is listed at just 5'11".
Mincone, a refugee from the Cubs organization, who played indy ball last year, turned 23 in July. In 22.2 innings, he's fanned 23 and walked three working with a fastball at 87 mph and a curveball at 78. That stuff will play in the New York Penn League and the SAL, but he'll run into trouble at the higher levels.
