Doc wrote up a prospect watch on SS Jeison Guzman.
After batting .186 (.571 OPS) over 11 games in May, Guzman found himself back in Burlington, where he showed more patience at the plate but managed only four XBH in 106 AB. Returning to Lexington on the 23rd of July, Guzman went 12-35 over his next ten games (.343/.378/.429), but plummeted to .215 over the remainder of the season (20 games, four doubles, one HR, four RBI).

But here’s the rub. The numbers don’t always tell the whole story. (WHOA!) The slider is his only pitch. Hitters recognize this and are laying off. They’re swinging at his slider just 41 percent of the time, by far the lowest of his offerings. And those numbers cited above in reference to his slider are relevant only when the ball is put in play.
