Name the Player

[Gantry]

He hates getting pwned by me, tough to blame him really

[Mike D.]

I've jerked off no less than 21 times to Johnny Bench.  Half the time I finished in my mitt...

[Gantry]

...

[Reds]

Oh dear.

[Mike D.]

It's plain as day that you were the one who edited that post.  This is really a slap in the face of all Dee-Nee, thinking we're too dense to figure this out.  Folks, his disdain for us common people is so evident it's repulsive.  It's time we organize.

[Reds]

Who did what now?

[Mike D.]

Oh dear, it appears that Gantry has correctly categorized at least one of us.  You're still special to me, Reds.

[Gantry]

I think he's having "issues" right now Reds, best just leave him be...

I don't like how McLane grades with lower case letters

I dont like how you graded my owl a fucking D.

Dang. Excellent choice.
The Mariners don't count in that?

[Big Hath]

Don Baylor?

do you guess him for all these questions?

[TempoGL]

Dang. Excellent choice.
The Mariners don't count in that?

They were either the 9th or 10th expansion team, depending on where you want to put the Blue Jays, so no.  Also, Don Baylor never played for them (not looking this up; I read his autobiography in 8th grade so I know a lot about his career)
