All those off-season questions should be answered within the next few weeks of Spring Training as roster spots, starting positions, and rotation vacancies are given to those who stand out. There are a significant amount of team members returning but nothing is set in stone, especially with the rotation and bullpen.
Besides the 1-2 punch at the top (J.J. & Nolasco) there are several talented pitchers vying for starter job. I think Anibal Sanchez is finally healthy and can put up a solid season like his stellar rookie campaign [10-3 with a no-hitter]. Chris Volstad has got to be over his sophomore slump by now because giving up as many home runs as games started  is unacceptable. If that leaves one more spot open it should go to a lefty, either Sean West or Andrew Miller. Both show sparks of being able to handle 7+ innings, but inconsistencies and inexperience need to be improved now that everyone knows their name and what they throw. The dark horse candidate would be The Incredible Hurk AKA Rick VandenHurk. He made big strides at the end of last season and you can’t go wrong with (future Hall Of Famer) Bert Blyleven as your personal pitching coach. That leaves Hayden Penn (who I don’t trust in the rotation) to become more of a middle relief like Burke Badenhop and Ryan Tucker, if not released altogether.
Another decision to make is who will fill that lefty off the bench roster spot. As early as it is in the spring the top 2 strongest candidates are Rule 5 draft pick Jorge Jimenez and veteran Mike Lamb. It seems manager Fredi Gonzalez has taken a likening to Jorge Jimenez and if so that could put the other Jorge (Cantu) back at 1B with his diminishing arm. On the other hand, in only 2 games Mike Lamb has 3 hits including a pinch-hit RBI single.
To throw another hat into the circle, Hank Blalock has still has yet to make a decision on which team he would rather play for this season. Blalock is choosing between the Rays and Marlins, so if he ends up signing with Florida he could very well snatch up that last roster spot over Lamb and Jimenez.
In a few days there will be a clearer view of things like Hank’s choice of whether to play in Tampa Bay or Miami, the “Race at First Base” between Logan Morrison and Gaby Sanchez, and the plethora of pitchers fighting for bullpen spots will dwindle because of injuries or lack of production. Check back after the weekend…
