Number 8: Roger Bailey (26 OPS+, 114 plate appearances)
Roger Bailey only played in the majors for three seasons but all three were with the Rockies. On those three teams (1995-97), Bailey hit .206/.252/.268. He had 20 hits including a double, a triple, and a home run. He also had eight RBI.
He had the most plate appearances in 1997 since he started 29 games for the Rockies but his best offensive season came in 1996 when in 25 plate appearances, he actually had an OPS+ of 113.
Number 7: Chris Rusin (29 OPS+, 95 plate appearances)
This one was another one that I was surprised by when I researched this.
Chris Rusin got more plate appearances as a Rockie earlier in his career due to being a starting pitcher for parts of the first two seasons in his five in a Rockies uniform.
While he was with a Rockie, though, he hit .227/.227/.284 with an OPS+ of 29. He went for 10-for-46 in his first season as a Rockie with an OPS+ of 27 but in his final two seasons as a Rockie (as a reliever), he had an OPS+ of 92 in 15 plate appearances.
Not bad if you don’t want to go through all of your pinch hitters or if you’re already out of them in extra innings.
