Winner: Challenge trade!
The Marlins traded pitcher Zac Gallen to the Diamondbacks for minor league shortstop Jazz Chisholm, an odd trade to make on July 31. The Marlins better hope Gallen isn't their next Chris Paddack or Luis Castillo. His raw stuff isn't on their level, but he has a 2.72 ERA through his first seven major league starts with 43 K's in 36.1 innings, suggesting he can pitch off a fastball that has averaged 92.2 mph.
Chisholm began 2019 as Arizona's top prospect, but he has struggled mightily in Double-A, hitting .204/.305/.427 with 123 strikeouts in 364 plate appearances. He does have 18 home runs, but just 11 other extra-base hits, so it has been an all-or-nothing approach. He's just 21, hits left-handed and can run, so he fits the Marlins' profile as a tools-laden position player with a questionable hit tool, but how many players who strike out 34% of the time in Double-A turn into good major league hitters? There's a chance the Marlins gave up a solid rotation anchor for Lewis Brinson II. Or maybe they hit a home run with a kid who develops into a power-hitting shortstop.”
