Not easy, is it? Some are prominent, some may have bright futures and some are ticketed to Rangers obscurity, like Travis Hughes, Jose Cecena, Sam Narron, Duff Brumley and Danilo Leon.
The Rangers' task during this cattle call is to figure out who is who. It's not easy and Texas isn't done, because there are still two weeks left before September callups. The Rangers are in position to blow past the 2002 Padres for most pitchers used in a season. They need one to tie and two to set the record.
Here's a look at the 36 to this point, in no particular order. Plus one.
Yu Darvish: He's a great talent with a mercurial personality, and he's definitely not just another one of the guys. But he's struggling to stay healthy, and he hasn't shown he can hold up for a full season yet.
Colby Lewis: A man of character, Lewis has made a remarkable comeback and has a good chance of returning next year. But he also just turned 35.
Neftali Feliz: Baseball as an industry is overly obsessed with velocity, but in Feliz's case, it has reached hysterical proportions. What it comes down to with him is command and execution at a lower speed. If Francisco Rodriguez can do it, why not Feliz?
Nick Tepesch: When he gets experience and masters the art of changing speeds, he could be something special.
Nick Martinez: The ultimate poster child for being rushed to the big leagues, Martinez just went head-to-head against Garrett Richards on Friday. Richards had 220 innings at Double-A and Triple-A; Martinez had 42 in Double-A.
Martin Perez: All things considered, Perez had the single-most painful injury on the staff this season after undergoing Tommy John surgery.
Matt Harrison: He said he won't try to start throwing again until November. Harrison's back condition is serious, but there are a lot of people hoping for a miracle.
Shawn Tolleson: The competition is nearing a conclusion. Tolleson has all but wrapped up the award for the best offseason acquisition. Some think he'll be even better next year after missing almost all of 2013 with back issues.
Neal Cotts: Somebody is going to regret not trading for him. We'll see if the Rangers are really serious about bringing him back.
Robbie Ross Jr.: He should have either stayed in the bullpen or not added the Jr. to his name. He'll probably go back to the bullpen eventually and remain a Jr.
Scott Baker: He deserves the Red Badge of Courage.
Tanner Scheppers: Gee, nobody saw this coming, and yet there are some who still think he can start. Not next year. He'll return to the bullpen, where somehow it seems he belongs.
Jason Frasor: Consummate pro. He's off to a great start in Kansas City, and he deserves it.
Joakim Soria: The Rangers got him out of town just in the nick of time. He's struggling with the Tigers, and he's now on the disabled list.
Roman Mendez: He has definitely made a favorable first impression, but his delivery gets erratic at times.
Miles Mikolas: He has a good breaking ball and knows how to change speeds, but his location has to be better.
Alex Claudio: Anybody around here remember Mike Venafro? Brian Shouse?
Jon Edwards: He can throw hard, but can he command it? Now, about that slider that buckled Erick Aybar's knees? Any more like that at home?
Pedro Figueroa: A hard-throwing left-hander down because of Tommy John surgery, the Rangers would have loved to seen him figure it out.
Nate Adcock: He is one of eight pitchers who averaged 93-plus mph with his fastball. But he needs a better breaking ball.
Phil Klein: He's starting to settle in with the Rangers. A few more good outings and somebody will want to put him in the rotation.
Alexi Ogando: Not everybody is a Hall of Famer. If he never pitches again for the Rangers, it was still one of the all-time great scouting success stories in franchise history.
Ben Rowen: Nice kid, funky delivery. Just curious: If you were allowed to bring back one former Rangers player, anybody you wanted, wonder how many would say Darren O'Day?
Aaron Poreda: Trivia question. Who had the highest average velocity with his fastball of any Rangers pitcher this season? The answer is this left-hander from the University of San Francisco, at 95.4 mph.
Matt West: He wins the award for hardest-throwing right-hander.
Joe Saunders: A great guy with a real nice career, but at some point, enough is enough.
Phil Irwin: The right-hander is currently on the disabled list at Triple-A Round Rock with a finger blister.
Ryan Feierabend: He's another left-hander who will keep getting one chance after another.
Hector Noesi: He is 7-7 with a 4.35 ERA in 20 starts and one relief appearance with the White Sox. Who of all the wise could have foreseen it?
Jerome Williams: The veteran made just two starts, but the guy did beat the Athletics. Not everybody can say that.
Seth Rosin: The former Rule 5 Draft pick is back in the Phillies' farm system, but he had a 6.26 ERA at Triple-A.
Justin Germano: He was sold to the Dodgers last week.
Daniel McCutchen: Released in June, he was last seen in the White Sox organization.
Mitch Moreland: Don't laugh. A former closer at Mississippi State, at least one Internet blogger has suggested a permanent position change.
J.P. Arencibia: There have been no such suggestions here.
Chris Gimenez: Ditto.
And finally ... Derek Holland: He wants to be here so bad. But it feels like the Rangers aren't going to let it happen, either as a precaution or punishment for starting it all.
