PHOENIX (AP) -Colorado right-hander Aaron Cook threw about 90 pitches in an instructional league game in Tucson on Wednesday and the Rockies were considering adding him to their postseason roster, along with center fielder Willy Taveras.
Cook is eligible to come off the 60-day disabled list this week. He could be ready to pitch Game 4 of the NL championship series against Arizona on Oct. 15.
Taveras has been out for almost a month with a calf injury. Rosters are due Thursday, before the start of Game 1.
Cook, who edged out left-hander Jeff Francis in a spirited competition for the opening-day start this season, was 8-7 with a 4.12 ERA when he was sidelined by an oblique injury Aug. 10.
``He threw seven innings, I heard he threw around 90, 90-plus pitches,'' manager Clint Hurdle said before the Rockies workout at Chase Field.
Cook showed that he was healthy, Hurdle said. But is he ready to step back in during the playoffs?
``No decisions have been made. We haven't set our roster,'' Hurdle said.
The Rockies were deciding whether it was best to go with Cook, who was 1-0 with a 5.63 ERA in four starts against the Diamondbacks this season, or right-hander Josh Fogg, who was 1-1 with a 2.63 ERA in his four starts against Arizona.
Francis will pitch Game 1 at Arizona on Thursday night and rookie right-hander Ubaldo Jimenez will throw Game 2 Friday night. Beyond that, Hurdle is keeping his rotation a secret, although it's likely rookie right-hander Franklin Morales will get the Game 3 start.
Another decision weighing on the Rockies was whether to risk spoiling the offensive cohesion that sparked their 17-1 run by reinserting Taveras into the mix.
Taveras is recovering from a calf injury that sidelined him for the last three weeks of the season and kept him out of the Rockies' sweep of Philadelphia in the first round. He ran Wednesday in hopes of convincing the coaching staff he was ready to contribute again.
Second baseman Kaz Matsui has been spectacular in the leadoff spot in Taveras' place and Ryan Spilborghs has played well in center field.
Right-hander Jason Hirsh (leg) also is healthy again but he's not being considered for a roster spot.
