(BaseballStL) -- Trevor Rosenthal is someone to really look at today in his bullpen session. He's got just a tremendous arm - regularly hitting 100 miles per hour on the radar gun - and has the confidence now given his impressive run in the postseason coming out of the bullpen.

These live sessions are going to go a long way in determining whether the Cards view him as a starter or as a reliever. With an opening in the rotation, there seems to be a way to get his dynamic arm out there every fifth day if the team so chooses. The problem is they've also got the likes of Shelby Miller and Joe Kelly on the team, too, who are more than capable of taking that role.

Rosenthal's success as a reliever last October could, in an odd way, hurt him in this starter competition. The Cards know - in fact they've seen it first hand - how impactful he can be coming out of the bullpen. And with Edward Mujica a year away from free agency, there might be a need in the later innings sooner than later here in St. Louis. Heck, even Jason Motte's only under contract for two more seasons. What if he's too expensive after that?

Do you want to see Trevor Rosenthal start or work out of the bullpen? Share your thoughts.

However, if Rosenthal were to show, starting today in live bullpens, that he's got three pitches ready to be used at the big league level, he could easily change their minds in that regard. Starters - after all - throw more than 200 innings during a season. Relievers throw just 70-75 or so. Many believe you're best pitchers should start. Simply because they throw the most.

So how the Missouri native does in these sessions will go a long way in helping the Cardinals decide exactly what he's going to be moving forward. Is he a starter? Or is he a reliever? Truthfully, the vibe I get here is he'll be pitching out of the bullpen. It's just a hunch. But that's the feeling I get with this team. There's a lot of starting pitching prospects coming up the system from Shelby Miller to Michael Wacha to Carlos Martinez.

There needs to be arms, power arms, coming out of the 'pen. Rosenthal fits that bill to perfection.
