According to TMZ Sports, Verlander and Upton wed in a small ceremony just days after Verlander won his first World Series title with the Houston Astros, beating the Los Angeles Dodgers 5-1 in Game 7 of the World Series.
After dating Verlander for three years, Upton made their engagement public last year, per Rebecca Macatee and Jimmy Chairman of E! Online.
The 25-year-old Upton had a visible presence throughout Houston's playoff run, and Verlander was a key part of the first championship in Astros history.
The former American League MVP and Cy Young award winner went 5-0 with a 1.06 ERA for the Astros during the regular season and followed that up with a 4-1 mark and 2.21 ERA in the playoffs.
