OK, so we've got the following that seem like essentially locks to me for the Opening Day roster: Outfielders: Soriano, DeJesus, Hairston, Schierholtz Infielders: Valbuena, Castro, Barney, Rizzo, Lillibridge Catchers: Castillo, Navarro Starters: Samardzija, Jackson, Wood, Villanueva, Feldman Relievers: Fujikawa, Russell, Marmol, Camp, Rondon I'd resisted putting Rondon as a lock in the past, but he looks good enough and there's not a bunch of other bullpen guys knocking down the door or anything. That's 21 spots. Bowden is out of options and has been outrighted before, so he can't be sent down without going through irrevocable waivers and being given the option to elect for free agency. He's pitching reasonably well and nobody else is going nuts in the pen to take the spot, so I think that has to go to him. They don't seem to be stretching him out as previously discussed, so that's 22. Ian Stewart apparently might start the season on the DL, so that's why he's not a lock, but if he's healthy he's almost surely No. 23. If he's not, Clevenger probably takes his place temporarily. Bogusevic still has some non-zero chance of replacing Sappelt for the final OF spot, though I will rage with a thousand doom boners if that happens. One of them will be 24. That just leaves the final spot, which seems very likely to be in the bullpen. You'd have to assume that would be between Rusin and Takahashi, both left-handed, otherwise Russell is the only lefty. I'd hate to see Cory Wade not given a shot, though, so maybe he can sneak in somewhere.
