The Windy City is now the high-five city.

Right-handed reliever Koji Uehara is the newest member of the reigning World Series champion Chicago Cubs after reportedly agreeing to a one-year, $6-million deal on Wednesday, according to Jesse Rogers of ESPN.

It was reported last week that the two sides had agreed to a deal, though the terms were not disclosed. Rogers adds that Uehara took less money to come to Chicago.

Uehara was one of the top relievers on the free-agent market as he remains highly effective despite entering his age 42 season. The eight-year veteran owns a 2.19 ERA, 0.81 WHIP, and 7.86 strikeout-to-walk ratio over the last four seasons with the Boston Red Sox wherein he also converted 79 saves.

While Uehara's been mostly durable throughout his career, a pair of injuries have interrupted his last two seasons. He suffered a broken right wrist in August 2015 after being hit by a line drive, and missed time last season with a strained pectoral.

The addition of Uehara now gives Joe Maddon three relievers with closer experience alongside Wade Davis and Hector Rondon.
