Number 57- Darryl Kile
Darryl Kile was the first player to wear the number 57 for the Rockies when he signed with the team before the 1998 season and after he came in 5th in NL Cy Young Award voting with Houston in 1997.
However, in the thin air of Denver in the pre-humidor era, the right-hander known for his big curveball struggled mightily as a Rockie as in two seasons, he pitched to a 5.84 ERA in 68 games (67 starts). After he left the Rockies, he went to play for St. Louis and in his first season there, he finished 5th in the NL Cy Young Award voting again, contributing to the “Coors” notion.
The only other player that wore 57 for the Rockies was Jason Jennings, who wore it in 2001 for his seven starts before switching to 32 in 2002.
Kile died of a heart attack at the age of 33 while with the Cardinals and while his number has never been retired by the Astros, Rockies, or Cardinals (the three teams he played for), none of the three teams have reissued his number after his death.
Number 58- Yohan Flande
Dom Nunez has an opportunity to overtake Yohan Flande here as Flande wasn’t particularly good but his competition (Dan Miceli, Juan Rincon, and Jordan Pacheco) aren’t great either.
In parts of three seasons as a Rockie, Flande went 3-9 with an ERA of 5.15 in 37 games (20 starts). He had a FIP of 4.92, a WHIP of 1.374, and a shaky 1.75:1 strikeout-to-walk ratio.
