On September 4, 2019, rookie pitcher Zac Gallen took a no-hitter into the 7th inning against the San Diego Padres, before surrendering a one-out single to Manny Machado. He had a 2-4 record in 12 starts entering the game in spite of an excellent ERA of 2.79, and once again was a victim of poor run support as the game was still scoreless when Machado reached base. He completed the inning with no further damage and then was the beneficiary of a four-run rally by his teammates in the bottom of the frame to end up a 4-1 winner, with three relievers completing his fine work. He had started the year with the Miami Marlins, making his major league debut on June 20th, then was traded to the Arizona Diamondbacks on July 31st, in return for minor leaguer Jazz Chisholm.
Gallen was originally drafted by the St. Louis Cardinals in the 3rd round of the 2016 amateur draft. On December 14, 2017, he was traded to Miami alongside Sandy Alcantara, Daniel Castano and Magneuris Sierra in return for OF Marcell Ozuna in the fire sale that followed the Marlins' acquisition by Bruce Sherman and Derek Jeter.
