If the Rockies decide to go with three starters in the first round of the playoffs, Jason Marquis will likely be pitching in long relief. That just doesn’t seem fair when you consider that he started 32 games so far this season in which he is 15-12 with a 3.95 ERA and a 1.36 WHIP. The Rockies would likely go with Ubaldo Jimenez, Aaron Cook and Jorge De La Rosa in the first round of the playoffs as the starting pitchers. Jimenez by far has the best stuff as he started 33 games in which he was 15-12 with a 3.47 ERA and a 1.23 WHIP. Aaron Cook is coming back from an injury. He started 27 games for the Rockies this season and he is 11-6 with a 4.16 ERA and a 1.41 WHIP. The lone lefty will be Jorge De La Rosa who is having by far the best year of his major league career. He has pitched in 32 games (31 starts) for the Rockies this year and he is 16-9 with a 4.45 ERA and a 1.40 WHIP. If the Rockies make it past the first round of the playoffs then Jason Marquis will rejoin the starting rotation.
