Cree was a small man (5 ft 6 in and 150 pounds).
In 1911, Birdie had an extraordinary season with 22 triples 48 stolen bases and a .348 batting average.
Many various injuries (including in 1910 when Cree was hit in the head by a Walter Johnson fastball in which he was knocked unconscious and carried from the field) as well as a badly broken wrist from a wild Buck O'Brien pitch in 1912 (this happened when he was hitting .332 after 50 games) helped prematurly derail his career. Cree left the sport with a .292 career batting average in 8 seasons.
