José Juan Arredondo (born March 12, 1984 in San Pedro de Macoris, Dominican Republic) is a Major League Baseball relief pitcher with the Cincinnati Reds.
Arredondo made his major league debut against the Chicago White Sox on May 14, 2008, at Angel Stadium in Anaheim, California. He surrendered a home run to Nick Swisher, the first batter he ever faced.
Arredondo earned his first career victory on May 26, 2008, against the Detroit Tigers in Anaheim, throwing two perfect innings of relief in an Angels' 1-0 12-inning victory. On June 28, he pitched in relief of Jered Weaver and combined with Weaver to not allow a hit against the Los Angeles Dodgers, but still lost the game 1-0. This was only the fourth time an eight-inning no-hitter had ever been lost due to the home team winning the game, and the first as a combined no-hitter. Because the Angels did not pitch nine innings, it is not officially considered a no-hitter.
