Baseball: the Round Rock Express, a Houston Astros affiliate, owned by Nolan Ryan and run by his son Reid.
Arena Football: Austin wranglers
Developmental Basketball: Austin Toros
Hockey: The Austin Ice Bats (the bats who live under the Congress Avenue bridge are Austin’s biggest tourist attraction, so a lot of things here are named for the bats)
Rancho Cucamonga Quakes - Angels Single A club
The Inland Empire 66ers (Dodgers Single A)are closer, but I wouldn’t travel to San Bernardino if you put a gun to my head, so that’s a non-starter.
I have the Buffalo Bisons, the Mets’ AAA farm team; the teams Little Nemo listed are within reasonable driving distance.
I think the logo is pretty cool !
I agree about the ballpark, though. I was there in 1999 when you had the AAA Braves. What I recall is that the place had no real personality at all, and was in fact rather dumpy for a AAA park. Looks like it hasn’t improved much in the last 11 years.
We have the Charlotte Knights (baseball, White Sox affiliate) and the Charlotte Checkers (NHL, Carolina Hurricanes affiliate.) There are also some independent league baseball teams like the Kannapolis Intimidators.
Except nobody from Buffalo ever drives to Rochester.
Never mind. 
Portland Winter Hawks - Western Hockey League. Cam Neely played for them, probably their most famous former player.
Portland Beavers - AAA affiliate of the Padres, although they’re moving away after losing the rights to play in PGE Park.
Portland Timbers, soccer team schecduled to move into PGE Park - vacated by the Beavers - in 2011. I don’t know enough about soccer to say whether that’s a minor league or major league team - they were USL <?> but will soon be MLS <?>
I’ve driven from Buffalo to Rochester. Granted, I’ve never actually stopped at either place.
Yeah, I’m sure opposing teams have to hold their noses in the dugout from the $h!t that’s scared out of them. Fear the squirrel, yeah boy.
The mascot is just something else entirely. My poor Wife had to attend the unveiling of that monstrosity with some students as a “reward”. (Video) If therapy in their mid-twenties is a reward, then sure. The opposing team might be laughing their asses off at him, but 6 yo kids are sure as heck terrified.
…and his damned name is Nutzy.
Here in the greater Youngstown, Ohio area, we have the Mahoning Valley Scrappers, the Rookie League minor league affiliate of The Cleveland Indians.
Just to show they take their heritage seriously, the Scrappers were defeated 12-0 last night in their first game of the season.
The team name (which of course has already has had all the insulting variations you just thought of applied to it many times over) appears to be in honor of the area’s steelmaking heritage…scrap iron, etc.
Former Indians third baseman Travis Haffner is the Scrappers’ manager.
Bowie Baysox - Orioles AA
Frederick Keys - Orioles “High A”
Potomac Nationals - Nationals A
Wow, guy does it all! A .794 OPS for the big team in Cleveland AND looking after a bunch of kids barely old enough to shave. Guy’s unbeliveable! 
I know, you meant to say Travis Fryman. Sorry 'bout that.
Heh. Okay the mascot’s not great, but I’ve definitely seen worse mascots over the years.
(…and I still think the logo is kid of cool! :))
Wandering off topic but there really is an element of truth to my joke. I used to live in Attica, which is a small town about halfway between Buffalo and Rochester (the two cities are about an hour’s drive apart). So I use to go to both cities on a regular basis. But I worked with people in Attica who were from Buffalo and they had literally never visited Rochester in their entire life.
That’s funny- The first time I saw a picture of…Nutzy…I thought of the Alley Cats mascot.
Who the heck has a vegetable as a mascot?
Long Island Ducks in the independent Atlantic League (baseball).
There are MLB related minors in Brooklyn and Staten Island. (Mets & Yanks, respectively)
You forgot the Ontario Reign the ECHL affiliate for the L.A. Kings.
As for the single A baseball, I’m closer to the High Desert Mavericks.…can’t remember who they are affiliated with.
Nobody’s even sure what Steamer IS!
Calgary Vipers - semi-pro baseball (Golden Baseball League)
Calgary Hitmen - Junior “A” hockey
Calgary Roughnecks - NLL lacrosse (I wouldn’t call this “minor league,” as it’s the top level of indorr lacrosse, but the OP included the Rochester Knighthawks, so I guess they fit the criteria)
I suppose you could also make a case for the CFL being a “minor league” as well, in which case the Calgary Stampeders should be on my list.
In years past, we also had a AAA baseball franchise (Calgary Cannons) and a WBL franchise (Calgary 88s). Damn, I enjoyed WBL basketball!
