1) Babe Ruth’s 1921 season — .378 average, 59 homers, 171 RBIs, 177 runs, 17 steals.
— The Great Bambino’s second year in pinstripes tops the list. Ruth hit 35 more home runs than any other player that year. He also drove in 32 more runs and scored 45 more runs than any other player that season. Ruth homered once every 9.15 at-bats while the average for all other players was one homer per every 96.43 at-bats. The Red Sox, who sold Ruth to the Yankees only two seasons earlier, hit only 14 homers as a team in 1921 — and the Curse of the Babe began. It was at this point that Boston owner Harry Frazee started to regret selling Ruth to the Yanks for $100,000 to finance his Broadway musical “No, No Nanette.”
2) Rogers Hornsby’s 1922 season — .410 average, 42 homers, 152 RBIs, 141 runs, 17 steals.
— Hornsby, the 1922 National League Triple Crown winner, became the first NL player to hit at least 30 homers in a season. He also led the majors in runs scored, and tossed in 17 steals for good measure. These statistics would be great for an outfielder — but Hornsby was putting up these gaudy numbers as a second baseman, where talent was thin.
3) Ty Cobb’s 1911 season — .420 average, 8 homers, 127 RBIs, 147 runs, 83 steals.
— Imagine a blend of Miguel Tejada and Scott Podsednik and you would have a guy that leads the league in RBIs and steals. That guy would be Cobb, who accomplished the rare double-double in the 1911 season, when he led the majors with 127 RBIs and 83 steals. He also led the league in batting average and runs scored, and strung together a then-AL record 40-game hit streak. It all added up to the Georgia Peach’s only MVP season.
4) Lou Gehrig’s 1931 season — .341 average, 46 homers, 184 RBIs, 163 runs, 17 steals.
— After eight season batting in the shadow of Ruth, Gehrig was finally able to match his teammate’s production in the 1931 season. Gehrig and Ruth tied for the home run crown (the first time Gehrig hit as many homers as Ruth in a season) and Gehrig edged Ruth for the RBI title. The 184 RBIs is still the second-highest single-season total in baseball history. The Iron Horse also led the majors in runs scored.
5) Hack Wilson’s 1930 season — .356 average, 56 homers, 191 RBIs, 146 runs, 3 steals.
— Wilson was only 5-foot-6 tall and wore a size 51/2 shoe, but he was a monster at the plate. He drove in a single-season record 191 runs while also leading the majors in home runs by seven round trippers. In fact, Wilson’s season was so stellar that baseball officials credited him with another RBI in 1999 after finding a scoring error in an old box score.
6) Jimmie Foxx’s 1932 season — .364 average, 58 homers, 169 RBIs, 151 runs, 3 steals.
— Foxx nearly matched Ruth’s old record of 60 homers in a single season, falling just two short and posting the third-best home run total at the time. He still managed to top the majors by 17 homers, lead the majors in RBIs and finish second in average and runs scored. Double X also picked up the first of his three MVP awards.
7) Larry Walker’s 1997 season — .366 average, 49 homers, 130 RBIs, 143 runs, 33 steals.
— Coors Field is a fantasy owner’s dream. The thin air even turned the weak-hitting Neifi Pérez into a star for a brief period. So when you put somebody as talented as Walker in that stadium, you get great numbers. Walker was just one homer short of becoming the first member of the 50 homer/30 steal club. The 1997 MVP also finished second in the league in batting.
8) Ken Williams’ 1922 season — .322 average, 39 homers, 155 RBIs, 128 runs, 37 steals.
— Who’s Ken Williams? He’s baseball’s first 30/30 man, and there wasn’t another for 34 years. There have been 22 30/30 men in the past 10 seasons, but it was unheard of when Williams accomplished the feat. The St. Louis Browns slugger also led the league in RBIs and finished in the top five in homers, runs scored and steals. Williams was the first true five-category player.
9) George Sisler’s 1920 season — .407 average, 19 homers, 122 RBIs, 137 runs, 42 steals.
— Sisler was probably the second-best fantasy player of the 1920 season (Ruth being the best), but he still registers in the top 10 single seasons. Sisler led the majors in batting average, and trailed only Ruth in homers, RBIs and runs scored. Sisler’s 42 steals were the third most in the majors. If Ichiro had a season similar to Sisler’s 1920 year, we would anoint him the best player in league history. But Sisler still gets little credit for his Hall of Fame career.
10) Barry Bonds’ 2001 season — .328 average, 73 homers, 137 RBIs, 129 runs, 13 steals.
— Bonds’ record-breaking 2001 season is arguably the seven-time MVP’s best season. He out-homered all players by nine dingers and drew a single-season record 177 walks. Bonds also finished in the top 10 in the bigs in runs scored and RBIs. Bonds homered once every 6.52 at-bats while all other players hit a homer every 30.78 at-bats. Not as impressive as Ruth’s spread but solid nonetheless.
Im not sure if this is scientific at all but none the less I think its pretty good.
