"When Yorvit Torrealba defected as a free agent, the prevailing opinion was that Chris Iannetta would take ownership of the catching position.

But with roughly three weeks left in spring training, Rockies manager Jim Tracy acknowledged it will be a time-share situation with Miguel Olivo.

At least initially.

"I can tell you this: They are both going to play," Tracy said. "I am not using the word 'platoon.' But they are both going to play."

Iannetta and Olivo are having strong springs. Iannetta is hitting .375. Olivo is batting .444, with five RBIs. Both have been starters in their career: Iannetta in 2008 and part of 2009 and Olivo last season with the Royals.

"I want to play and he wants to play," Olivo said. "But he's my partner, and I am not looking at it like a competition."

Cook update.

The line over his last two outings is gruesome — 15 runs allowed in 5 2/3 innings. But Aaron Cook is not about to panic.

"I have been doing this too long to worry. It's just going to take a couple of more games than normal," said Cook, who was tagged Tuesday for six runs and six hits by the White Sox.

The right-hander remains encouraged by strong bullpen sessions, proving to him nothing is wrong mechanically with his delivery."
