10. Pedro and Ramon Martinez
Accomplishments: Pedro: Three AL Cy Young awards, one World Series title; Ramon: 135 wins, 3.67 ERA, 1990 NL All-Star
There once was a time where Pedro was merely considered Ramon's little brother. The elder Martinez won 135 games in his 13-year career, including 20 games as a rookie in 1990, and also threw a no-hitter in 1995. Everybody knows his brother Pedro, who won the AL Cy Young Award three times for the Boston Red Sox and was one of the most electrifying pitchers to watch in the last 20 years. The brothers actually pitched together in the same rotation on two different occasions, first in 1993 for the Los Angeles Dodgers and then again for the Red Sox in 2000 and 2001.
