A native of
Somerville, Massachusetts, Blanche was the son of Italian emigrants and the youngest of four children. He attended
Somerville High School, and played
college baseball at
Providence College, graduating with a degree in philosophy in 1934. While at Providence, he played summer baseball in the
Cape Cod Baseball League (CCBL). In 1931, he began the CCBL season with
Wareham, but finished the season with
Falmouth. In 1933 and 1934, he pitched for the league's
Harwich team, winning the decisive third game of a three-game championship series sweep for Harwich over Falmouth. Blanche caught on with the big league Braves near the end of the
1935 season. Though it was the end of a dismal campaign for the Boston club, Blanche posted an impressive 1.56 ERA in 17 innings over six appearances. His debut came on August 23, when he tossed four innings in relief of
Ben Cantwell, allowing two earned runs and smacking a hit in the Braves' 7–5 loss to the
Pittsburgh Pirates at
Braves Field. His best outing came on September 29 in the first game of a home
doubleheader against the
New York Giants and hurler
Al Smith. With the Braves down 5–2 after three innings, Boston starter
Ed Brandt was lifted for Blanche, who finished with six strong shutout innings in the eventual 5–3 loss. Blanche began the
following season with Boston, now known as the "Bees", appearing in 11 games and posting a 6.19 ERA in 16 innings before being optioned to the minor leagues. He made one appearance with the
Syracuse Chiefs, then finished out the 1936 season with the
Columbia Senators of the
Sally League. In 1938, he was back in the CCBL with
Orleans. Over his two major league seasons, Blanche tossed 33 innings with a 3.78 ERA and eight strikeouts. He went 2-for-10 at the plate, and committed two errors in 16 chances in the field. Blanche served in the
United States Air Force during
World War II, and died in 1997 in
Melrose, Massachusetts, at age 87. ==References==
