what is the record for most rbi in a single season by a player?
470478
Hack Wilson (1930) - 191
572451
27 triple doubles.  And is only player to have a triple double in the All-star game.  He was amazing. See source.
1182358
Albert Pujols, hands down
636161
Has to be Sandy Koufax.  0.95 ERA in four World Series!
546171
A batter is awarded 1 RBI (runs batted in) for each runner that can cross home plate after his hit. In the case of a home run, this would include 1 RBI for himself.
550501
Shockingly Barry Bonds set this record in 2001, on his way to 73.  He had 39 at the all-star break.
1093261
How good can he be?  He's in his sixth season, so that's five complete seasons.  IF he can stay healthy for a 20 year career, at his averages after 5 seasons (multiply them by 4 for a 20 year career), you're looking at:\n\n3928 hits, 3rd all time behind Rose and Cobb\n2516 runs, 221 ahead of Rickey Henderson's record\n908 doubles, 116 ahead of Tris Speaker's record\n804 home runs, 49 ahead of Hank Aaron's record\n2484 RBI's, 187 ahead of Hank Aaron's record\n7336 total bases, 408 ahead of Aaron's record\n1604 walks, 11th all time\n.418 OBP, tied for 10th all time\n.629 SLG, 4th all time behind Ruth, Williams and Gehrig\n.331 BA, tied for 21st all time - appropriately enough, with Musial
1094927
Hugh Jennings 287\nCraig Biggio, 277\nTommy Tucker, 272\nDon Baylor, 267\nRon Hunt,243( 50 in a single season)
779999
Lou Gehrig had 184 in 1931.\n\nhttp://www.baseball-reference.com/g/gehrilo01.shtml\n\nhttp://www.baseball-almanac.com/recbooks/rb_rbi1.shtml

I would have to say it was Wilt Chamberlain. He Averaged 30.1 points per game over his career and averaged about 50ppg one season!!! Here is a link to his career stats! http://www.nba.com/history/players/chamberlain_summary.html "ew..pick me, pick me..lol"

Walks and HBPs count as RBIs, as do sac bunts and sac flies. If the batter grounds into a double play, he does NOT get credit for an RBI. He also doesn't get credit if the run scores on a passed ball, wild pitch or error.\n\nCheck out rule 10.04:
55721
Would have to say Babe Ruth. Not only did he hit 714 home runs, which stood as the major league record for nearly 40 years, but he was a career  .342 hitter with a .474 on base percentage. If that's not enough, he was also one of the best pitchers the game has ever seen with a 94-46 record a 2.28 career ERA and still holds the record for consecutive scoreless innings pitching in the World Series.
654883
Baseball Reference says Walt Dropo of the '52 Tigers, with 12.\n\nTed Williams has the record for most consecutive times on base, with 16 in '57.
1024368
Alan Wiggins.  70 steals, 106 runs scored.  Almost no one even remembers him.
634942
Hank Aaron is correct, he had fifteen 30-homer seasons.\n\nAll time leaders with most 30 homer seasons are:\n\nHank Aaron  15 seasons\nBarry Bonds 14\nBabe Ruth   13\nMike Schmidt 13\nJimmie Foxx  12\nFrank Robinson 11\nMark McGwire  11\nSammy Sosa  11\nWillie Mays 11\nEddie Matthews 10\nHarmon Killebrew  10\nLou Gehrig  10\nRafael Palmeiro 10

GreenCaddyMan needs to read the question.  Ken Griffey Jr. hold's the the record for most Home Runs in the month of April, not September.\n\nBut yeah as for the real answer it is Albert Belle.  I just wish he didn't get hurt and have to retire as soon as he did.  He was a big help to the Orioles before he left the game!

If he keeps this up, so far he is a potential triple crown candidate, he is on the pace to breaking the previous home run record of 73.  I just named a couple records.  lol
