Vinicio "Vinny" Castilla Soria (Spanish pronunciation: [kasˈtiʎa]; born July 4, 1967) is a Mexican former Major League Baseball third baseman who played his best years with the Colorado Rockies and Atlanta Braves.

Previously, he played with the Atlanta Braves (1991–1992, 2002–2003), Colorado Rockies (1993–1999, 2004, 2006), Tampa Bay Devil Rays (2000–2001), Houston Astros (2001), Washington Nationals (2005), and San Diego Padres (2006).

For the 1993 season he played regularly hitting nine home runs, nine triples (8th in the league) and 30 RBIs in 105 games as a shortstop.

In 1994, his playing time was reduced due to the acquisition of shortstop Walt Weiss and the 1994-95 Major League Baseball strike.

After the departure of starting third baseman Charlie Hayes, Castilla was the leading candidate to man third base for the 1995 season.

He finished the season with a .309 batting average, 32 home runs, 34 doubles and 90 RBIs, earning his first Silver Slugger Award.

Many considered Castilla's numbers to be a fluke because he played his home games in the friendly confines of a thin-air Denver stadium, a stigma that would follow Vinny for most of his Colorado career.

[4] During the Monterrey series in Mexico, Castilla switched briefly to number 14 on his jersey, in honor of former Rockies first baseman Andrés Galarraga (then with the Atlanta Braves), who was diagnosed with cancer and missed the entire ‘99 season.

Prior to the 2000 season, Castilla was sent to the Tampa Bay Devil Rays, a team that featured veteran sluggers Jose Canseco, Greg Vaughn and Fred McGriff.

Although his offensive numbers declined (.232/12/61), he established himself as a premier defender at third base, leading the league in fielding average with .982.

He returned for a second stint with the Colorado Rockies for the 2004 season and had a tremendous year, hitting 43 doubles and 35 home runs, and led the league with 131 RBIs.

Defensively Castilla had arguably his best season at third base, leading the league in fielding average and committing only six errors all year long.

He decided to retire after the Caribbean Series on February 7, 2007, becoming a special assistant to Rockies GM Dan O'Dowd.
