Born in Mill Valley, California, Freitas attended Tamalpais High School in the mid-1920s. His father, who was Portuguese, was reluctant to allow Freitas to play baseball because of his duties on the family farm. Freitas was ultimately allowed to play for the school's baseball team while his older brothers, George and Arthur, tended to the cows.[2]
He was recruited by the Senators, playing with two of their Arizona farm clubs in 1928 and 1929. He moved up to the PCL with the Senators during the 1929 season.[3] He won 19 games in both the 1930 and 1931 seasons.
After pitching a no-hitter on his birthday in 1932, Freitas moved up to the Philadelphia Athletics for two seasons, followed by three with the Cincinnati Reds. He went back down to the minors during the 1936 season, returning to the Sacramento team (by then named the Solons) in 1937.
Freitas served in the U.S. Army Air Corps during World War II from 1943 to 1945[4] and was stationed at Mather Air Force Base.[5] He returned to the PCL with the Solons after the war, playing there into the 1950 season. He completed his 25-year playing career with four seasons in the California League, playing for the Modesto Reds in 1950 and 1951 and for the Stockton Ports in 1952 and 1953. He was the manager of the Solons in the 1954 and 1955 seasons.
With 342 wins in the minors, Freitas is fourth all-time and is the winningest left-handed pitcher. He won 20 or more games nine times. He has been selected for the Pacific Coast League's Hall of Fame and for its All-Century Team.
