For Marlins pitcher Zac Gallen, the wait is over.
The Marlins rookie will make his Major League debut against the St. Louis Cardinals, the team that drafted him and traded him last offseason in a deal with Miami to acquire outfielder Marcell Ozuna. Gallen has torn up the Pacific Coast League, earning three Pitcher of the Week honors and had proven regardless of his current position as the Marlins 18th ranked prospect by MLB Pipeline, he is as close to a sure thing this organization has.
There is some pressure in this kind of situation.
