Zac Gallen is the biggest story of the Diamondbacks season.
Sure, the trade of Zack Greinke made much bigger waves but we've been expecting a Greinke trade for over 3 years.
The trade of the Diamondbacks top prospect for a little known, previously fringe prospect in Zac Gallen is actually a much bigger deal for the Diamondbacks organization.
And after an impressive debut, Mike Hazen has proven his foresight once again.
The trade of Jazz Chisholm for an organization like the Dbacks was a major risk. Chisholm has legitimate superstar tools. But he's also struggling in Double-A. Gallen, who entered the season as the 19th best prospect for the Marlins lowered his ERA to 2.40 over his first 8 career starts.
Zac Gallen does more than just buoy the team's starting rotation, he reinforces something every Dbacks fan should take comfort in: Mike Hazen knows what the hell he is doing.
Hazen has shown a willingness to take risks and so far, those risks have paid off. He's overseen the trade of Paul Goldschmidt and Zack Greinke and also the free agent departures of AJ Pollock and Patrick Corbin.
Those were the 4 most prominent Dbacks over the last decade for this team. Losing four stars is usually crippling for any team but the Dbacks have a brighter future today than any point over the last few years.
So yeah, Zac Gallen is a big deal and that makes Mike Hazen an even bigger deal.
