KANSAS CITY, Mo. (AP) Infielder Juan Uribe was added to the New York Mets' World Series roster after recovering from a chest injury, while 20-year-old infielder Raul Mondesi Jr. joined the Kansas City Royals' roster ahead of Game 1 on Tuesday night.

Uribe, who has not played since Sept. 25, took the spot of backup shortstop Matt Reynolds, who was on the NL Championship Series roster but has never played in a major league game.

Uribe injured chest cartilage while making a diving stop on Sept. 20, then aggravated the injury on a swing while pinch hitting Sept. 25. He batted .219 with six homers in 44 games, playing second and third base after the Mets acquired him from Atlanta in late July.

Mondesi, the son of former big leaguer Raul Mondesi, took the place of speedster Terrance Gore on Kansas City's 25-man roster. He replaced reliever Joba Chamberlain on the 40-man roster.

If he appears in a game, the versatile, switch-hitting Mondesi would become the first player in major league history to make his debut in the World Series, according to STATS.

Mondesi is considered one of the Royals' top prospects, but he spent all season at Double-A Northwest Arkansas, where he hit just .243 with six homers and 33 RBIs.

He was chosen for the World Series roster over Gore, a member of last year's AL championship team, fellow infield prospect Cheslor Cuthbert, and veteran outfielder Jonny Gomes, who has not been part of the Royals' postseason rosters after getting acquired late in the season.
