The Washington Nationals have become a World Series contender, and their latest addition to the team’s roster has been a big reason why.

The Nationals announced on Tuesday that they had designated outfielder Tyler Wilson as the club’s Opening Day starter.

Wilson is a 23-year-old outfielder who spent the past two seasons with the Atlanta Braves.

He has an impressive .302/.369/.464 slash line in the majors over parts of two seasons.

He hit .267/.339/.439 in his first two seasons in the big leagues, and he has yet to walk in a major league game this year.

Wilson will start the season in the minors for the Nationals.

The move will be Wilson’s fourth stint with the Nationals after he signed with the club in January 2017.

Wilson, who turns 22 on Wednesday, had one plate appearance last week against the New York Mets.

The 23-man roster is set to be released on Tuesday at 3 p.m. ET.
