He started that season playing 22 games with the Tigers before being sold to the Red Sox in mid-August.

He was listed as a possible replacement for the injured Dave Shean, but never got a chance to play in the World Series.

Coffey is the only player to play with both Ty Cobb and Babe Ruth in the same season (1918 Tigers and Red Sox).

In two seasons, he played in 110 games and had 368 at bats with 33 runs, 69 hits, 5 doubles, 6 triples, 1 home run, 26 RBI, 6 stolen bases, 22 walks, a .188 batting average, .241 on-base percentage and a .242 slugging percentage.

He returned in 1922 as the school's first full-time coach and remained there until 1958 (Fordham did not field a team in 1944), amassing 1,160 wins.
