"Although their careers are at far different locales entering this season, both prospect Shelby Miller and reliever Mitchell Boggs see spring training as an important place to assert their place in the organization.

Miller wants to use it to make the majors this season.

Boggs wants to show he can do more than stick in the majors.

"I feel like I've got a lot to prove this year," said Boggs, the Cardinals' righthanded reliever who spent a brief moment as the closer in 2011 before moving into a less-defined role. "Mentally, I'm in a better place than I've been in the past couple years. ... I've got high expectations. the last couple years -- they've been good, but they haven't been great. I feel like I can be great. ...

"I look forward to backing that up.""
