A native of Strasburg, Virginia, McQuillen attended what is now McDaniel College in Westminster, Maryland, and reported immediately to the Browns upon signing with them in . In his first professional and Major League game, he hit a double as a pinch hitter off Johnny Marcum of the Boston Red Sox, collecting his first run batted in during a 12–8 loss at Sportsman's Park.[1] McQullen batted an MLB career-high .284 that season, collecting 33 hits in 43 games with St. Louis. He then spent 1939, 1940 and most of 1941 in minor league baseball at the upper levels of the Browns' farm system. After a seven-game recall to the Browns during September 1941, McQuillen spent all of on the St. Louis roster, when he posted career highs in games (100), runs (40), hits(96), and RBI (47), while hitting for a .283 average.
McQuillen enlisted in the United States Navy before the 1943 season, serving on the destroyer in the Pacific Theater of Operations for three years before rejoining the Browns during the 1946 and 1947 seasons. In, he again spent a full season with the Browns, but he could not crack their starting outfield and his batting mark fell to .241.
In a five-season MLB career, McQuillen was a .274 hitter (176-for-643) with four home runs and 75 RBI in 210 games. Following his major league stint, he spent 10 years playing and managing in the minors, leaving baseball after the 1956 season.
