Tokyo Yakult Swallows is a professional baseball team in Japan's Central League.

The Swallows are named after their corporate owners, the Yakult Corporation. From 1950 to 1965, the team was owned by the former Japanese National Railways (known as Kokutetsu (国鉄) in Japanese) and called the Kokutetsu Swallows; the team was then owned by the newspaper Sankei Shimbun from 1965 to 1968 and called the Sankei Atoms. Yakult purchased the team in 1970 and restored its original Swallows name in 1974. Then it was renamed the Tokyo Yakult Swallows in 2006.

The team's mascot is a black and white swallow with a red face named Tsubakuro. He is known for his feuds with the Orix Buffaloes mascots.

The number on the back of his uniform is "8960" as opposed to 111/222 used by Buffalo Bull and Buffalo Bell, the Buffaloes' mascots.

There is also a female swallow mascot named Tsubami. She wears a skirt and may be intended as Tsubakuro's little sister, just as Bell is Bull's little sister.

Wladimir Ramon Balentien (Dutch pronunciation: [ˈvladimir balənˈtin]; born July 2, 1984 in Willemstad, Curaçao, Netherlands Antilles) is a Nippon Professional Baseball outfielder with the Tokyo Yakult Swallows.

Balentien was signed as an undrafted free agent by the Mariners in 2000. He spent his first five professional seasons in the minor leagues, playing for the Arizona League Mariners, Wisconsin Timber Rattlers, Inland Empire 66ers, San Antonio Missions, and Tacoma Rainiers, before being called up in September 2007.

In 2007, Balentien was selected to the All-Star Futures Game in San Francisco, a result of his .328 batting average, 20 home runs, and 66 runs batted in by that point. He was called up to the Mariners on September 4, 2007, and played that very night against the New York Yankees at Yankee Stadium. Balentien pinch-hit for José Guillén in the 8th inning, and hit a two-run double in his first major league at-bat.

Balentien was invited to spring training with the Mariners in 2008 and signed a one-year deal with the team. However, the starting job in right field went to Brad Wilkerson, and Balentien was optioned to Triple-A Tacoma on March 24. When Wilkerson and first baseman Greg Norton were designated for assignment on April 30, Wladimir and Rainiers teammate Jeff Clement were called up to the big leagues for a game in Cleveland against the Indians.
