The Rockies' experiment with a four-man rotation and a 75-pitch limit for starters is over. However, the Rockies' decision makers continue crunching numbers to determine the most efficient roster construction. The club is toying with the idea of keeping eight relievers at home and seven relievers on the road, freeing a spot for an additional bench player.
"It's a fluid situation," director of major-league operations Bill Geivett told The Denver Post. "We are trying to find the best pitching model."
Geivett discussed the possibilities with the pitchers Monday, and it was addressed in individual meetings last week. The home-road splits were dramatic last season, creating an argument for roster flexibility. The Rockies' relievers worked 50 ⅓ fewer innings on the road, making an eighth bullpen arm a luxury.
Last season, the Rockies, spiraling out of contention, made a radical adjustment June 20, switching to a four-man starting staff with three "piggyback" relievers. The starters were slightly better after the switch, but the bullpen's performance was worse, likely as a result of a huge workload. The Rockies' relievers worked a major league-record 657 innings last season, 238 more than the next-least-used bullpen (Phillies). The relievers' .274 average against was the worst in baseball.
