Peter Joseph Coscarart (June 16, 1913 – July 24, 2002) was a second baseman and shortstop in Major League Baseball who played from 1938 through 1946 for the Brooklyn Dodgers and Pittsburgh Pirates.

Coscarart was a graduate of Escondido High School in California, where the baseball field was named after him.

He later was signed by the Dodgers, becoming the first big leaguer coming out of San Diego State University.

[1] Considered the top defensive second baseman in the National League in 1939, Coscarart finished that season with a .277 batting average, 22 doubles and 10 stolen bases.

[2] Coscarart also was a member of the Brooklyn team that faced the New York Yankees in the 1941 World Series, but as his hitting declined, he was replaced by Billy Herman and then traded to the Pittsburgh Pirates before the 1942 season.
