Number 36- Gabe White
Ironically, for players, Tommy Field is the only position player to wear the number as he wore it for two plate appearances in 2012. For the pitchers, the best one to wear number 36 is Gabe White.
White spent part of two seasons as a Rockie (2000-2001). The Rockies acquired him just a few days after Opening Day in 2000 and his 2000 season is why he won. In 68 games out of the bullpen, he went 11-2 with an ERA of 2.36 with an ERA+ of 247, a WHIP of 0.940, and a pitching bWAR of 4.5.
He regressed a lot in 2001, though, as he pitched to a 1-7 record and a 6.25 ERA in 69 games.
Number 37- Joe Kennedy
Joe Kennedy spent part of two seasons as a Rockie (2004-2005) and in 2005, he was the Rockies Opening Day starter.
In the 1.5 seasons as a Rockie, he pitched to a 3.9 bWAR. He pitched to a 5.6 bWAR in 2004 so obviously, he regressed a lot in 2005. The Rockies traded him to Oakland in July along with Jay Witasick for Eric Byrnes and Omar Quintanilla.
Just over two years after the Rockies traded him to Oakland, he died at the age of 28 due to hypertensive heart disease due to a degenerative mitral valve.
