Who are these frickin guys?!?

If you've been watching any of the Twins spring games so far (I've yet to miss one), you've undoubtedly seen a few names that are unfamiliar. Not uncommon, of course, for spring training.
The Twins don't have too many spots available on their big league roster, but there are several players who they're looking at to see if A) they might one day be ready, and
B) how soon that might be
Here are some names to know. Though I should point out this list is limited to prospects who are in the big league camp. There are lots of other potential studs who are still several years away.

Blue-chippers
*Denard Span - OF (pictured above right)
Think Jacque Jones with more speed and less power.
A former 1st round pick, Span began last year in A ball and hit .339 with 13 steals, prompting a call up to AA, where he hit .285 with 10 steals. It looks like the Twins are trying to decide if he's ready for AAA. He just turned 22, and if Torii Hunter ends up getting traded in the next year or two, this guy is his replacement.
*Alex Romero - OF
Once considered a marginal prospect, Romero, 22, broke through in AA last year, hitting .301 with 15 HR and 12 SB. Being that he developed so suddenly, the 6', 190 pounder possibly still hasn't tapped his full potential. He's by no means a can't miss prospect, but he has a shot to be a five-tool stud.
*Matt Garza, Glen Perkins - P
Both are 22, and both at least a year away. But they were both high draft picks and they've both impressed the coaching staff this spring. They could both be in the bigs next year. Garza is a righty, Perkins a lefty.
*Justin Jones - P
The guy from the Doug Mientkiewicz trade, Jones was 7-3, 3.01 at A ball last year. He's still only 21, and if he stays healthy could be a very good big league pitcher.

At the Ready
*Boof Bonser - P
The third guy in the AJ-Joe Nathan trade, Bonser was the AAA staff ace last year and led the league in K's. He's probably ready for the big leagues, the Twins just don't need him. He's probably a 3rd or 4th starter at best, but he could probably help the Twins out of the pen, especially if Juan Rincon's elbow doesn't get better soon.
*Dave Gassner - P
Soft tossing lefty is 27, but looked good in winning his ML debut with the Twins early last year. He's a good guy to have in AAA. Probably won't ever be a 15-game winner in the big leagues, but is always available to fill in if someone goes down.
*Darrel May, Denny Reyes - P
One of these two veteran lefties will make the team. Reyes throws hard but is wild, and he's had success against lefties as a reliever before (righties are another story.)
May is a soft-tosser and a former starter. Much like Greg Swindell a decade earlier, May's career as a starter has washed out, so he's trying to reinvent himself. Swindell rejuvenated his career making the move, and May, who has excellent control, might be able to as well.
*Willie Eyre - P
27-year old righty is a favorite to land a spot in Twins bullpen this year. He was 10-2 with a 2.71 ERA in AAA last year, so he's due for a shot. Could be the next Tony Fiore.
*Glenn Williams - 3B
This guy might be the Twins starting 3B this year if he hadn't seperated his shoulder last year. You may remember him hitting .425 after getting called-up, before the injury ended his season. That was his one big chance. Now he'll likely go back to AAA.
*Terry Tiffee - 3B/1B
Promising in '04, terrible last year. Looks like a pinch-hitter at best. I hope he doesn't make the team.
*Luis Rodriguez - IF
Spent most of last year in the bigs and I thought he was pretty good. He batted .269/.335/.383 in 175 ABs, far better than Castro and Punto. I'd love to have him beat out one of those two for a job, but since he's still young and has options, he'll probably start the year in AAA. He'll be back, though, and I think he could be a great utility player.
*Garrett Jones - 1B
If something disastrous would happen to Justin Morneau, Jones would be his likely substitute.
He's hit 54 homers over the past two seasons at AAA, but was just .244/.297 OBP last year. He could hit for power in the big leagues, but would probably struggle to hit .200. He's a career minor leaguer. Would probably be good in the Northern League.
*Chris Heintz, Rob Bowen, Shawn Wooten - C
None of these guys will ever amount to more than Tom Prince status, but they're good to have around. All three are capable back stops, while Wooten and Heintz (both veterans) have decent pop with the bat.
*Jason Tyner - OF
A speedy LH hitter with no power, Tyner, 29, probably belongs in the big leagues. He fared well in a call up last September, and has looked good this spring. If the Twins had an injury to their OF, Tyner is a better option than most teams have in AAA.
*Andres Torres - OF
Similar to Tyner but not as polished, Torres has ML experience and could help out in a pinch, but he'll be a career minor leaguer.
*Luis Maza, Tommy Watkins - IF, Josh Rabe - OF
I'd be surprised if any of these guys ever reach the Twins. They're not bad players, but they're not big leaguers. They help fill out a AAA roster.

Mid level prospects
*Jason Pridie - OF
A former top prospect of the D-Rays, Pridie would be a great addition to the Twins AAA roster, but unfortunately he's a Rule V pick, which means the Twins have to keep him in the ML all year or lose him - the same way they got Johan Santana.
Pridie has shown promise, but he's got about a 2% chance of making the team.
*JD Durbin - P
If you saw him pitch against the Reds Monday night, you saw how horrible he is. As recently as two years ago the "Real Deal" as he called himself, was arguably the top pitching prospect in the organization. But a total lack of command, maturity and possibly intelligence has him falling fast.
*Errol Simonitsch - P
A 6-foot-4, 23 yr old lefty, Simonitsch dominated A ball last year, then fared decently at AA. He's a little old to still be in AA, but he's got good stuff.
*Adam Harben - P
Similar to Simonitsch but a righty, Harben won 10 games with a 2.69 ERA in A ball last year.
*Jose Mijares - P
A 21-year old lefty with great stuff, Mijares is raw but talented. He might be the guy to eventually take JC Romero's role.

Just happy to be in camp

*Kevin Cameron, Jason Miller, Pat Neshek, Ricky Barrett - P
These guys have all put up solid numbers in the minors, but that's where they'll stay. They're either too old or simply don't have the tools that scouts want, regardless of how well they pitch in the minors.
