Law: Thoughts on stunning Miami-Arizona prospect deal and more deadline trades

Law: Marlins betting big on upside of Chisholm (1:33)

Keith Law contends that the Marlins are betting on Jazz Chisholm's upside after acquiring him from the Diamondbacks. (1:33)

One of the more shocking moves of the day was Arizona's trade of perhaps their top prospect, shortstop Jazz Chisholm, to the Marlins for pitcher Zac Gallen. Chisholm is electric on all sides of the ball -- he has incredibly quick hands, he's at least a 7 runner, and he's erratic but rangy and quick at shortstop, with the potential to come into a lot of power as he continues to fill out. He is raw at the plate, more so than I realized coming out of a successful 2018 campaign; he's hit just .204/.305/.427 this year as a 21-year-old in Double-A (young for the level) with a strikeout rate of 33.8 percent. If he's coming out of college into the draft right now -- he's the age of a junior and won't turn 22 until February -- he's a top-15 pick, and even that is speculative because we almost never see college position players with his kind of tools and athleticism; George Springer might be the last comparable such draft prospect. The Marlins must be ecstatic to get this kind of upside.
