Probably the most famous would be the record of most rushing yards in a Super Bowl- Timmy Smith (?) Washington Redskins, 204. I forgot the year.
Nate Colbert (double ??), San Diego Padres, once hit 5 homers with 13 rbi in a doubleheader- not technically an official record I don’t think, though.
Any others?
Most consecutive putouts by a catcher. It’s a record that seems pretty obscure, but, if you think about it, it should be pretty obvious.
Hint: What is the most common way for a catcher to get a putout?
Jerry Grote!! I have correctly answered a sports trivia question; I can die a happy man.
The record for most points scored in an NFL game is held by someone I’ve never heard of, although my football-knowledgeable friends claim that it’s a somewhat well-known stat.
Various all-time baseball records are held by random people from the late 1800’s, and are thus generally ignored as irrelevant to today’s game.
Johnny Vandermeer is pretty obscure aside from his record of two no-hitters
Harvey Haddix is pretty obscure aside from his record of 12 perfect innings in one game
Don Larsen is pretty obscure aside from his record of fewest hits in a World Series game
Owen Wilson is pretty obscure aside from his record for most triples in a season
I’d say Jason Elam is pretty obscure.
For those who don’t know, he is the kicker for the Denver Broncos who tied Tom Dempseys record for the longest NFL field goal at 63 yards.
In addition, the record for doubles in a season (67) is held by Earl Webb, who is famous solely for doing that. He did not hit 67 doubles in his next two best years combined. He only played about four or five seasons’ worth of games and did nothing else of any note.
The record for most RBI in a game (12) is shared by Jim Bottomley and Mark Whiten, two players of middling talent who are known for little else.
The record for most strikeouts in the first nine innings of a game is shared by three pitchers whom you would expect–Roger Clemens, Kerry Wood, and Randy Johnson. But the record for most strikeouts in a game is held by the thoroughly obscure Tom Cheney, who fanned 21 in 16 innings (yes, he pitched all 16) for the 1962 Washington Senators.
Yeah, Ernie Nevers was a great player in his day. If he’s forgotten today, other than because of the record, it’s only because most pro football stuff from that far back is forgotten.
IIRC, on a strike out, the pitcher is credited with an assist, and the catcher is credited with the putout.
Freddy the Pig:
You’re unaware, then, that Jim Bottomley is in the Hall of Fame?
No, I’m not joking.
I was unaware, yes.
What was it with old-time Cardinals in the 1970’s? They let Jesse Haines in, too.
Here’s another obscure fact about Nevers: He gave up two home runs of Babe Ruth’s 60.
Most of the players who had unassisted triple plays in the majors are pretty obscure. Some had solid careers, but they are not known for anything else.
Sorry to nitpick but I think we need some rules for this thread. In particular, people like Ernie Nevers or Jim Bottomley who are in the Hall of Fame for their particular sports don’t really qualify as “obscure.” Even is the modern casual fan might not know who the guy is now, athletes who make the Hall of Fame are, by definition, those who exhibited consistent excellence in their sports over a significant period of time. This thread is about people who had short and/or unremarkable careers except for that one fluke season, game, or moment when they set a record.
Many of the pitchers who had perfect games are Hall of Famers or at least were very good pitchers, but others had poor to mediocre careers.
Lee Richmond 75-100
Charlie Robertson 49-80
Don Larsen 81-91
Len Barker 74-76
Mike Witt 117-116
From NDP’s Bottomley link:
There are just not enough people these days who swear by the sinews of Joshua. 
Inspired by tonight’s Arizona-Florida game:
19 rookies have thrown no-hitters since 1900 (including Anibal Sanchez tonight.) Of them, only 8 recorded more than 100 wins, and only 2 more than 200 (Vida Blue and Christy Mathewson.)
Prior to tonight, the St. Louis Cardinals had two in a row. They were from two of the most obscure pitchers you’ll ever find: Jose Jimenez, who less than a year later was closing for the Colorado Rockies, and Robert “Bud” Smith, who would appear in just 11 games for the Cardinals the next season before being traded along with Mike Timlin and Placido Polanco to the Phillies for Scott Rolen.
Who was the first black head coach in the NFL?
Art Shell, you say? Sorry; it was Fritz Pollard.
I just learned this tonight. It was news to me; I’d never heard of him.
The Veteran’s Committee was utterly in the thrall of Frankie Frisch, who bullied them into inducting a variety of his old teammates from the Giants and Cards:
Jesse Haines
Chick Hafey
Jim Bottomley
Ross Youngs
Rube Marquard
Dave Bancroft
George Kelly
Fred Lindstrom
To be quite honest Frisch kind of wrecked the Hall of Fame; none of these guys should be Hall of Famers, and really Bottomley is the only guy who’s even close; he’s sort of equivalent to Don Mattingly. I could probably come up with 400 players who are not in the Hall of Fame who were better than George Kelly or Chick Hafey.
Jesse Haines wasn’t any better a pitcher than Mel Stottlemyre, Chick Hafey didn’t have any better a career than George Bell, Jim Bottomley was Don Mattingly, Ross Youngs wasn’t half the player Fred Lynn was, Rube Marquard was no better than Dave Stieb, Dave Bancroft wasn’t really any better than Dave Conception, George Kelly as a Hall of Famer is a fucking joke - he was not half the player John Olerud was - and Fred Lindstrom didn’t have as good a career as Graig Nettles.
I disagree with your assessment of Ross Youngs, at the minimum. He died in the prime of his life from Bright’s disease, and the numbers he put up were more than adequate to merit inclusion if you factor in the idea that he would only have been more noteworthy had he not died.
The other choices on your list are also more than acceptable when you consider that Roger Bresnahan and Rabbit Maranville are also in the Hall. There are numerous “shady” picks in the Hall, but that scarcely devalues the rest of them. It’s not like the Rock and Roll Hall of Fame where inclusion seemingly comes from being a one-hit wonder. There are MVPs and Cy Young Award winners that are not in the Hall and shouldn’t be, but in my opinion everybody who is in the Hall has nothing to be ashamed of.
Roofies?
