Do STATS matter ?

Sure stats matter but it depends which ones you are talking about. The only player who I can see matches your description is John Axford who was 3-8 his final year at Canisius. In 226 minor league innings, he has a career 3.66 ERA. At Staten Island in 2007, his ERA was in the low 2's.

Wins/Losses for a pitcher are often out of their control and thus are likely not that important. Their height, weight, and velocity are important physical stats as Axford is 6'5" tall.

At some point early in their minor league career, a pitcher has to prove he can get them out (especially a 42nd rounder). The ERA is a pretty reliable indictor of that ability. Sometimes there are extenuating circumstances. If a pitcher is rehabbing from injury, he might have lessor stats for a year or two while returning to health.

As an example, Andrew Brackman is a Yankees first rounder in 2007 who is coming off TJ surgery. At 6'10" and a guy who can throw in the high 90's when healthy, they will give him a lot of leeway on his stats which are not very good this year (2-12, almost 6.00 era).

He was actually 1-8 in college competition. The 2 wins came in exhibition games here in St Catharines.
John had TJ surgery while at Notre Dame 3 years prior to Canisius.
The stats that matter are 6'5 and the mid 90s FB.
The point I was making was that guys who worry about stats shouldn't. The stats are not the Major considerations.

BHD,
All this proves is that the W/L record does not matter, as a stat. It doesn't mean all stats don't matter.
If this young man is 6'5" and has a mid 90's fastball, why were over 1,200 players selected before him?
Why wasn't he drafted until the 42nd round when you present two "stats" about his size and velocity that would suggest top 5 rounds, or higher.
Of course some stats matter. It just depends on which stats you include. Those stats that measure individuals skills and productivity on a baseball field matter.
Those stats that reflect the collective team results usually do not.

Actually the stats listed are considered very good for a milb pitcher (though he was older than most player in lower level), and also depends on which leagues he played in. And I also agree that other stats are very important for pitchers (height, velo). If you look closely you will see how they rushed him through this year, most likely because of his age. He's now up against it's now or never shot. This happens sometimes when a team is not in playoff contention as well.

FWIW, the player is 26, most players at that age have been called up at one time or another on most teams, if they produce, they are kept by most teams, sometimes just for fill in for injury, help with the bullpen due to tired arms, etc, if they don't produce, they are gone.

I don't mean to be negative, but you have to present the whole scenerio. I wish the young man lots of luck and success, but MLB is what it is and a september callup can sometimes be your last.

There is an awful lot of talent out there, and MLB players are getting younger and younger each year, 26-27 has become the break point for most.
