When half of your team’s schedule is played in a ballpark that increases
run production by fifty percent, the manager has to be able to adjust his
thinking to account for that distortion. As the Colorado Rockies’ manager
since their inception, Don Baylor has been the only man who has had to
operate within this skewed reality on a daily basis. This altitude-induced
twisting of the truth shows up in the data for their starting pitchers. For
example, at first blush, their quality start percentage of 40% seems
unacceptably poor, and certainly ranked near the bottom of the league.
However, breaking that number into a home/road split, we find that the
percentage of quality starts was 49% on the road and 30% at Coors Field.
Figures like this further reinforce the idea that the 1998 Rockies sunk to
the depths of the National League West primarily because of their inability

to score runs, not prevent them. So how did Baylor manipulate this
underrated staff, and what can new manager Jim Leyland learn from the man
who survived six years in the harsh pitching environment of Planets Coors?
Let’s examine Baylor’s tendencies starter by starter:

  • Marquee free agent Darryl Kile left the pitcher’s haven of the Astrodome
    and signed with Colorado during the off-season. Baylor put him on display
    often, as Kile’s 35 starts tied for the league lead–heck, Baylor even used
    him once as a reliever. He was regularly moved up in the rotation in place
    of an injured or struggling teammate when an off-day presented the chance.
    Kile is still not economical with his pitches, and on six occasions Baylor
    allowed him to exceed the 125-pitch mark. But it wasn’t Baylor’s heavy
    usage that caused Kile to resurrect memories of Brian Kingman–it was Coors
    Field. Kile posted an excellent 72% QS+BQS on the road versus 35% in Denver.

  • Pedro Astacio pitched very well after joining the Mile High Club in
    mid-August 1997 after a trade from the Dodgers, which led to high
    expectations for 1998. Those expectations came crashing down when Astacio
    had only one quality start in his first eleven trips to the mound. Baylor
    used him in the same way that he used Kile, which enabled Astacio to toss
    nearly 210 innings despite his ineffectiveness. Although Astacio had the
    misfortune of making 19 of his 34 starts at home, this doesn’t help to
    explain his poor campaign. He was equally unproductive home and away (42%
    QS+BQS at Coors, 40% on the road).

  • Despite being only 23 years old, 1998 was Jamey Wright‘s third season in a
    Rockies uniform. As in his previous seasons, Wright was plagued by
    inconsistency. He was most successful when working on four days’ rest (52%
    QS+BQS), which may have encouraged Baylor to use him more than he should
    have. Wright was even chosen (along with Kile) to work on three days rest
    while Baylor mulled over bringing somebody up from the minors to replace
    the disabled John Thomson. While Baylor should be commended for keeping
    Wright’s pitch counts lower than those of his veteran starters, Wright
    still finished the year with over 200 innings pitched–too many for such a
    young arm.

  • John Thomson was arguably the Rockies most effective starter in 1998. Of
    course, he benefited from having 15 of his 26 starts closer to sea level,
    where he threw 9 of his quality starts. The 24-year-old redhead was
    especially sharp in the middle of the season–from late May through
    mid-August he had 9 QS in 11 outings despite missing nearly six weeks with
    a finger blister. As with Wright, Baylor generally kept Thomson’s pitch
    counts low. However, unlike Wright, Thomson was never moved from his slot
    in the five-man rotation because of off-days. Baylor monitored him
    carefully, as evidenced by his zero blown quality starts.


Baylor gave the first two opportunities at the five-spot in the Rockies’
rotation to a couple of guys with a dangerous combination–historically
weak peripheral numbers and recent shoulder surgeries. Mark Thompson opened
the season following rotator cuff surgery in 1997. He admitted that his
shoulder was still weak after not logging a quality start in his first six
tries. The weakness was eventually diagnosed as a partially torn shoulder
muscle, ending his season. Fear not, riding to the rescue was Colorado’s
all-time leading winner, Kevin Ritz–fresh off of surgery for a torn
labrum. Baylor apparently didn’t notice the 13-0 shellacking that Ritz
suffered in his last rehab start in Triple-A. Ritz was pathetic in two
outings before also complaining of shoulder weakness, which finished his
year. Now 34 years old, Ritz’ best chance of getting back on a major league
mound is a door-to-door sales position in suburban Seattle.


Desperate for a fifth starter, Baylor turned to chronically wild southpaw
Bobby Jones (that’s Bobby M. Jones), who began the season as the twelfth
man in the bullpen. Jones found the plate often enough to earn 3 QS+BQS in
his first three attempts, thereby solving Baylor’s pitching dilemma. Before
his season ended with a sprained knee in mid-September, Jones was the
surprise of the Rockies staff, finishing with 55% QS+BQS (including 8 of 9
on the road). Perhaps Baylor should have watched him more closely, as Jones
weakened in the late innings and led the team with four BQS.


Both Mike Saipe and Mark Brownson logged a couple of starts with the Rox
while Thomson was on the DL. Each had one quality start (Brownson’s was a
complete game shutout over the Astros) before being shipped back to
Colorado Springs when off days enabled Baylor to skip the fifth starter’s
spot. Although neither had much Triple-A experience prior to 1998,
seasoning shouldn’t be used as an excuse as to why Baylor didn’t give one
or both a longer look later in the year. The D-backs weren’t exactly
threatening the Rockies stranglehold on fourth place.


The Rockies rotation made 111 starts on four or fewer days’ rest–the
highest total of any team looked at so far. The core starters (Kile,
Astacio and Wright) primarily shouldered the burden, as they were
consistently shifted up in the rotation when the schedule permitted. Baylor
tried to reconcile this by generally keeping pitch counts reasonable and by
pulling his starters when they showed fatigue–10 BQS doesn’t seem like a
bad number for a team based on Planet Coors. It was discouraging that
Baylor didn’t attempt to plug-in any of his minor league moundsmen towards
the end of the campaign, but he may have been engaging in a vain attempt to
save his job. Free agent pitchers are beginning to use Colorado as nothing
more than a bargaining chip at the negotiating table due to prior
disappointments in Coors (Swift, Saberhagen, Kile). The reality is that
pitching at 5000 feet isn’t a great career move, so the development of
young arms takes on extra importance in the Rockies’ organization. Advice
for Jim Leyland: (insert Santana soundtrack) "You’ve got to change your
evil ways."
