Guillermo Reynoso Mota (born July 25, 1973, in San Pedro de Macorís, Dominican Republic) is a Major League Baseball relief pitcher for the Los Angeles Dodgers.

Mota was signed as an undrafted free agent by the New York Mets in 1990 out of high school. Originally a third baseman, he made his professional debut with the Gulf Coast Mets in 1993. In 1994 he played with the Kingsport Mets in the rookie leagues, hitting .245 while striking out 78 times in 245 at bats. The Mets switched him to shortstop the following season and he spent 1995 with the Columbia Bombers and 1996 with the St. Lucie Mets, continuing to strike out a large percentage of the time.

He was selected by the Montreal Expos in the minor league portion of the 1996 Rule V Draft, and the Expos converted him to a pitcher with the Class-A Cape Fear Crocs. He made 25 appearances for the Crocs, including 23 starts, and was selected to the South Atlantic League mid-season All-Star team.
