Mark Mulder was in the same shoes as Roy Halladay once.

After having a great career with the Athletics, Mulder joined the Cardinals in 2004 and helped them reach the NLCS before losing to the Astros, but the next season was much different.

Mulder started the season with a plus-6 ERA and it was then revealed he had rotator cuff problems and missed the rest of the season.

Mulder, a 100 game winner in the majors joined Mike Gill and Todd Ranck on Monday to discuss what he's seen from Halladay and why it looks so familiar.

"A guy just doesn't lose 2 or 3 mph off your fastball without there being an issue," Mulder said.

Halladay struggled to start the season, but seemingly turned the corner after putting together consecutive good starts, including one against the Pirates where the next morning he woke up with shoulder soreness.

The two outings that followed Halladay gave up 17 earned runs in just six innings of work and was placed on the DL today with shoulder inflammation.

"You start to question yourself and negative thoughts come into your head and you just cant get people out," Mulder recalled.
