So what I wrote down (and it's hilarious as I was mistaken - we only got one speed reported on a change-up!😅):
First wild pitch was a beauty - off speed classic down and in to a lefty. I put it on Cabrera or just his massive movement (he was credited with 3 WP, mind you). More a testament to his stuff than being 'wild'. Cabrera mistakenly tried to backhand catch a sinking inner off-speed headed to the dirt. He needs to move and block it.
Would have loved to see the first pitch of his fourth batter on an accurate Gamecast - dropped a dime of a curve/slurve right on the outer stripe called a ball. Gorgeous pitch. 1-0 felt unfair.
2nd WP was indeed wild. High and outside went off-speed low and in. Runners advanced.
3rd WP - all 3 came in his first frame - and this one was also an off-speed pitch that ran away.
Appears to have a sinker as well as possibly two types of heat? Would love to hear it from Rivero himself or the pitching coaches. Also has a slider. A curve/slurve. And, maybe even a change-up. Lots of tools. He can go straight four-seam riser OR he can go sink OR he can go tailing two-seam by my eyes.
Robbed of another K second batter of 7th - beautiful outer half heater. It was a K. Eye test matters. He's been wild, yes, but in these lower levels the stats often lie.
Change-up drops to 81 mph - so, yes, definitely a change-up I am seeing in addition...
Slider appears to be a notch higher - I'd bargain 85-86. He opened up the 8th with a slider K.
Back-to-back K's via the slider. Clearly a strikeout pitch.
Final out on another pop-up. Lotta pop-ups induced. Hardest hit ball was an oppo liner run-scoring line drive single.
So given that change-up and what appeared to be a low to mid 80's slider I'm going 93-95 mph on the heat when he dials back. But, not verified.
