Catchers: Carlos Corporan, Sean Coughlin and Konrad Schmidt.
Infielders: Jeff Bailey and Mark Hallberg.
Outfielders: Collin Cowgill, Evan Frey and Drew Macias.

More details and analysis of the 17 men in question can now be found after the jump - and, no, I didn't read Zephon's  I Hate South Bend's comments before writing my report...

Pitchers:

• T.J. Beam - Born in Scottsdale, Beam was drafted by the Yankees in 2003. Over seven seasons in the minors, he has a decent 3.35 ERA, but got torched in Las Vegas last year with the Jays AAA affiliate. Has made 52 MLB relief appearances over two seasons, with a 5.37 ERA.
  
• Josh Ellis - Ellis moved up from Mobile to Reno after posting a striking 1.94 ERA at Double-A. However, in 15 games for the Aces, he allowed 17 ER in 19.1 IP. Overall, he gave up 20 homers in 61 innings of work last year. Went 3-0 with a 3.44 in Venezuela this winter, so no rest for him.
  
• Barry Enright - One of the mainstays of the Mobile rotation in 2009, Enright made 27 starts for them, going 10-9 with a 3.98 ERA. A 2007 second-round pick, see Zephon's exhaustive profile on both him and Roemer, from this site in July 2008
  
• Kyler Newby - Kinda remarkable N00b is still about, having been the 1,485th pick of the 2004 draft [though #1,496 has made it to the majors, Chris Davis being the Rangers' regular 1B last year]. K-rate dipped sharply with his promotion to Mobile this year, and his HR rate regressed to normal too.
  
• Rodrigo Lopez - Certainly a possible contender for the #5 spot in the rotation, and not lacking in experience with 166 starts in the majors since his 2000 debut. A career 92 ERA+, and at age 34, probably should not really be expected to get much better than "serviceable."
  
• Wes Roemer - One of our supplemental sandwich picks from 2007, Roemer started the year at Visalia (High-A), but six solid outings and a 2.05 ERA later, he was promoted to Mobile. He made 22 starts for them, going 9-9 with a 4.28 ERA. Has a Twitter account.
  
• Bryan Shaw - As Shaw has yet to face anyone above A+ ball, this seems more like a courtesy invite than anything else That's especially the case, as he didn't exactly light up the mound, with a 4.70 ERA over 102.2 innings of work, both as a starter and in relief.
  
• Matt Torra - Seems to have been about forever, and after spending half of 2008 in Triple-A, was back down in Double-A for the whole of 2009. Got to like a K:BB ration better than 4:1, but turns 26 in June, and is now getting old for his level.
  
• Tommy Layne. The sole left-hander on the list has had a busy winter. He appeared in the Arizona Fall League, and then jetted off to make two starts for Criollos de Caguas in the Puerto Rican Winter League. However, those didn't go too well, as he allowed ten hits and six walks in 5.1 innings.
  

Catchers:

• Carlos Corporan - The guy has a 439 OPS+ in the majors! Ok, what this actually means is, he hit a single in his only at-bat to date, for the Brewers in May last year, but small sample size be damned! Pay no attention to the .244 average over seven minor-league seasons...
  
• Sean Coughlin - Had a rather good year with the bat, in particular at Mobile, where he hit 304 with a .917 OPS, the highest numbers by any player there with 150+ PAs. The player so nice, we picked him twice: first in the 42nd round of 2006, and then again up in the 13th round of the '07 draft.
  
• Konrad Schmidt - Despite the name, he was born in Santa Rosa, California. Was the main catcher for Visalia, where he batted (what are the odds?) .304, getting him a cup of coffee in Reno. I'm thinking probably back in Mobile for 2010.
  

Infielders:

• Jeff Bailey - Before the arrival of LaRoche there was some discussion as to Bailey's potential value as a platoon partner for Brandon Allen. Now, he's more likely to be a substitute, though still has a shot at the 25th spot on the major-league roster.
  
• Mark Hallberg - Saw time at both 2B and SS for Mobile. Seems to be a farm version of Augie Ojeda, with solid defense (five errors in 113 games at those two positions), but little offensive pop - a .648 OPS, with his OBP actually higher than his SLG.
  

Outfielders:

• Collin Cowgill - Another polite invitation, given this 5th-round pick was in High-A all of last season. After tearing up short-season ball in 2008 [11 HR in just twenty games], Cowgill regressed a bit at Visalia, but stil hit .277 there, while playing both in center and right.
  
• Evan Frey - Don't expect power from this center-fielder; after three years and 323 minor-league games, he has just four home-runs. Does have some wheels, with 81 SB in that time, though a .686 OPS in Mobile suggests he'll be there again when the season starts.
  
• Drew Macias - Played 51 games for the Padres last year, though mustered only 90 PAs and a .197 average in that time. Didn't do much better (.232) in Triple-A, and has to be considered a long shot to be any more than Reno roster filler, unless bubonic plague hits the 40-man roster.
