The Houston Astros and the Los Angeles Dodgers faced off Saturday night in Game 4 of the World Series in Houston, Texas. The Dodgers walked away victorious ... but the real winner was Hailey Dawson of Henderson, Nevada, who threw out the first pitch.

As you might remember, Hailey is on a quest to throw out the first pitch at every major league ballpark. It's a big dream, considering Hailey is only 7 years old ... and uses a robotic hand due to a congenital defect that left her short three fingers since birth.

Hailey has been on the pro circuit since 2015, when she threw out the first pitch at a Baltimore Orioles game. But things really took off last month, when Bleacher Report tweeted about her dream to toss the first pitch at every park.

Hailey was flooded with invites from MLB teams, including the Minnesota Twins, Detroit Tigers, New York Mets, Milwaukee Brewers, Seattle Mariners and the Oakland A’s. With baseball season winding down, Hailey's mom told TODAY last month that they expected to hit most of the ballparks in 2018 — but it would appear that when the World Series comes knocking, you don't tell it to wait!

The Nevada native got her own custom "Vegas Strong" cleats, as well as a specially made World Series hand that featured an Astros logo. The hand, which is made with a 3D printer, is the eighth one Hailey has worn since receiving her first in October 2015.

"She's really a terrific young lady," MLB Commissioner Rob Manfred said after meeting Hailey at an event. "It's an honor for Major League Baseball to have her here to throw out the first pitch. It's an amazing scientific and medical accomplishment."

Congratulations, Hailey ... and here's to many more!
