Who is Sebastian Walcott? 5 things to know about the Texas Rangers’ star prospect

If you’re a Texas Rangers fan and aren’t aware of Sebastian Walcott, you should probably change that.

Walcott, a 19-year-old prospect from The Bahamas, has turned into one of the best prospects, not just in the Rangers organization, but in all of baseball. He is a 6-foot-4 shortstop oozing with tools, talent and potential.

Here are five things to know about Walcott.

1. The basics

Name: Sebastian Edward Walcott

Date of birth: March 14, 2006

Measurables: 6-4, 190 pounds

Birthplace: Nassau, Bahamas

Bats: Right Throws: Right

2. Got paid early

Walcott signed with the Rangers in January of 2023 as a part of Texas’ international free agent class.

Walcott, who was just 16 years old at the time, received a $3.2 million signing bonus to join Texas. The Rangers bet most of their $4.144 million international free agent pool on Walcott, and so far, that appears to be a very good bet.

He was ranked the No. 8 prospect in MLB Pipeline’s rankings of that year’s international class.

3. Teenage star

Walcott has spent the 2025 season at Double-A Frisco and is in some rarefied air. He is one of four teenagers to play at the Double-A level so far in 2025 and is the second-youngest player in the Texas League.

He became the first teenage prospect to start at shortstop for the RoughRiders since Jurickson Profar and Elvis Andrus.

Walcott has been incredibly successful in his first season at Double-A, too. As of June 9, he’s first leaguewide in runs scored (41), first in doubles (15), tied for 11th in home runs (8) and owns a .248/.349/.437 slash line that’s made him one of Frisco’s best statistical batters.

“He’s a great player,” RoughRiders manager Carlos Cardoza said, “and he has all the ingredients to be great at the highest level.”

4. Elite prospect

Walcott, 19, is the organization’s consensus top prospect and one of baseball’s best. He is No. 4 on ESPN’s top prospects list, No. 6 on Baseball America’s and No. 8 on MLB Pipeline’s as of June 9. He also played in the All-Star Futures Game at Globe Life Field in 2024.

Here are some of the things said about Walcott as a prospect ahead of the 2025 season.

“It’s not normal,” Rangers president of baseball operations Chris Young said during spring training. “You don’t see [teenagers] have one, the ability to perform at this level like he has, and two, the progress that he’s made, his aptitude, his willingness to learn. ... It’s just so impressive, the sky is the limit for him.”

“He’s just incredibly talented, and he’s doing things you wouldn’t expect of a guy his age,” Baseball America’s Josh Norris told The Dallas Morning News.“He’s got very little professional experience, relatively speaking, and he’s still mashing and showing all sorts of flashes of these loud tools that usually are reserved for guys that become superstars.”

5. Learning championship habits

Walcott was invited to his first major league camp in 2025, and he ended up with an unofficial mentor during spring training: Marcus Semien.

Walcott’s first big league locker was right next to Semien’s in the Rangers’ spring clubhouse, and he spent spring training picking the seasoned veteran’s brain. Semien is known for an outstanding work ethic throughout his career and was the captain of the Rangers’ 2023 World Series team.

“It’s awesome having Marcus as a locker mate,” Walcott said. “He’s easy to talk to, we can talk about anything. Working out, baseball, outside of baseball. We talk about almost everything. He’s just a great guy to talk to. He’s also a great guy to get advice from. He’s been in the game so long and he’s achieved so much.”

“I’m always trying to lead by example,” said Semien. “When I was his age, I wasn’t even in pro ball, so it’s a whole other level when you’re in college and seeing how the upperclassmen do it. He’s already a step ahead of that. He gets to watch major league players do what they’re doing at a very young age. He’s not very far off.”
