Paul Sewald married Molly Sewald in December 2017. They got engaged on Dec. 9, 2016, and were married about a year later.
The two have one child together, a daughter, who was born in August 2021.
Molly was born on April 4, 1992, in Sacramento, California. She graduated from Arizona State University in 2015. She previously worked as a civil engineer for Kimley-Horn & Associates.
Sewald described what it was like when his wife went into labor without him. Sewald has faced some of the toughest hitters in Major League Baseball, and he'd choose that over missing the labor of his wife every single time.
"Nervous, anxious, worried I wasn't going to get on the first flight from Seattle down to Las Vegas," he was quoted as saying by Seattle Refine. "It happened very quickly. I've likened it to: I would rather race the bases loaded in a game than worry about not getting home to your wife who is in labor. It was a little tricky. I made it back. She had a tough night without me, which I'll never be able to live that down, but I was there for all the most important parts and that's what matters most."
Sewald has bounced around the league, spending time with the Seattle Mariners before the Diamondbacks, who just lost to the Texas Rangers in the World Series.
The Diamondbacks couldn't complete the dream season, falling in five games.
