3) José Buttó
Mets prospect José Buttó has been formidable so far this season. After two years in which he went up and down the minors, putting up unremarkable numbers, this season seems ideal to unleash his full potential.
Buttó had concentrated in his career on being a pitcher with practically two pitches, his fastball, with a speed average close to 94 mph, and his change-up, which is his signature pitch, was rated by scouts with a grade of 70 on the 70/80 scale. However, his profile was not able to get the opponents out of the way.
His fastball is still efficient and achieving a good level of swing and miss, but it is the adjustment in his changeup and the greater use of his sinker that has achieved a better level on the mound. The pitch is achieving a whiff higher than 45% thanks to a better combination and use in the strike count with his fastball to get hitters out of time. Likewise, his sinker, which he used only 5.6% of the time, is being used 23% of the time, with which he has managed to generate a batting average for his opponents below .100.
Buttó looks like the pitcher the Mets expected him to be at the fourth-in-a-rotation level. With the injuries that affect the rotation, Butto is achieving the task, putting pressure on him to stay in it for the remainder of the season.
