Dietrich posted the first two-home-run game of his MLB career, and his three RBIs boosted the offense in Miami's 5-0 win over the Reds on Saturday at Great American Ball Park.
The Marlins were held without a hit until Dietrich homered off Anthony DeSclafani to open the fourth inning. Miami scored three runs in the inning, and in the seventh inning, Dietrich tacked on a two-run blast off Manny Parra.
"Any time you can put runs up on the board for your starting pitcher early, I think it just helps him settle in -- everybody, your defense, everybody," Dietrich said.
The left-handed-hitting third baseman is getting starts against right-handers because Martin Prado (right shoulder) is on the disabled list.
Dietrich's homer in the fourth was a no-doubter. Statcast™ tracking projected the towering drive to be right at 438 feet, with an exit velocity of 106 mph.
Nicolino, making his MLB debut, made the early run support hold. The lefty threw seven scoreless, and Miami snapped its three-game losing streak and a six-game road slide.
"I wanted to go out there and just give the guys a chance to win," Nicolino said. "They picked me up in the fourth with Dietrich hitting the home run, and then adding on two more, and I was able to relax a little bit more. It was just one of those ball games, take everything in and enjoy it."
Dietrich now has three homers in eight games since he was called up from Triple-A.
"I'm just happy that we got some runs early for [Nicolino], and he was able to settle in pitch like he knows how," Dietrich said.
