Luis Vizcaíno Arias (born August 6, 1974 in Baní, Dominican Republic) is a Major League Baseball right-handed relief pitcher for the Colorado Rockies.
Vizcaíno was signed by the Oakland Athletics as an amateur free agent in 1994. After gradually working his way through the Athletics minor league system, he made one relief appearance for the A's in 1999, 12 in 2000, and 36 in 2001, but continued to spend significant time in AAA. In 2002, he was traded to the Texas Rangers for pitcher Justin Duchscherer, and the Rangers in turn traded him to the Milwaukee Brewers for Jesus Pena.
In his three years with the Brewers, Vizcaíno was a workhorse. After an outstanding 2002 (5-3, 2.99 ERA, 76 appearances), he slumped badly in 2003 (4-3, 6.39 ERA, 75 appearances) before having a bounce-back 2004 campaign (4-4, 3.75 ERA, 73 appearances). Milwaukee then sent him to the Chicago White Sox as part of the Scott Podsednik for Carlos Lee trade.
With the White Sox, Vizcaíno had another solid year, going 6-5 with a 3.73 ERA in 65 appearances for the 2005 World Champions (he pitched one scoreless inning during the World Series in his only playoff appearance). After the season, Chicago traded him to Arizona.
In 2006, Vizcaíno went 4-6 and posted a 3.75 ERA in 70 games for the D-Backs.
On January 9, 2007, Vizcaíno was traded to the New York Yankees with three prospects for Randy Johnson. releases/press_release.jsp?ymd=20070109&content_id=1775804&vkey=pr_nyy&fext=.jsp&c_id=nyy" target="_blank">http://newyork.yankees.mlb.com/NASApp/mlb/news/press_releases/press_release.jsp?ymd=20070109&content_id=1775804&vkey=pr_nyy&fext=.jsp&c_id=nyy He achieved a rare feat on July 21, 2007 when he was credited with both wins in relief in a day-night doubleheader for the Yankees, joining about 30 other pitchers.
