Ranking the 40 greatest individual seasons in MLB since 1940 is no easy endeavor. But MLB Network did just that, revealing its top 40 seasons on Sunday night. To say the list is impressive is an understatement. From starting pitchers with ERAs below 2.00 to hitters slugging over .700, here are the best single-season performances of all time.
No. 40: Rickey Henderson, 1985
The all-time stolen-base king swiped 80 bags, while also hitting 24 home runs and slashing .314/.419/.516. Henderson walked 99 times and struck out only 65 times in 654 plate appearances.
No. 39: Mike Marshall, 1974
Coming off a season in which he finished as the runner-up in National League Cy Young Award voting, Marshall claimed the honor in '74 after turning in an even better campaign. The right-hander posted a 2.42 ERA in an MLB-record 106 relief appearances for the Dodgers. He also set an MLB record by pitching 208 1/3 relief innings.

Fidrych -- who was known for his unorthodox style on the mound, which included talking to the baseball -- was also runner-up in AL Cy Young Award voting.
No. 31: Tony Gwynn, 1987
Gwynn, who was most known for his incredible eye at the plate, hit .370. But he also posted career highs in stolen bases (56) and triples (13), while winning his second Gold Glove Award in right field.

No. 25: Vida Blue, 1971
At 22, Blue became the youngest pitcher to win an AL Cy Young Award, as he started 39 games and posted a 1.82 ERA in 312 innings for the A's. He was also named the AL MVP that season, after tossing 24 complete games -- including eight shutouts.
No. 24: Joe Morgan, 1976
Morgan was an integral part of Cincinnati's Big Red Machine that won back-to-back World Series titles in '75 and '76. While Morgan was named NL MVP in '75, he was even better in '76 -- slashing .320/.444/.576 with 27 home runs and 60 steals, as he was named MVP for the second straight season.
No. 23: Willie Mays, 1955
In the season following his famous over-the-shoulder catch in the World Series, Mays followed up his '54 MVP campaign with another outstanding showing on the field. He slashed .319/.400/.659 with 13 triples, 51 homers and 24 steals for the Giants.
No. 22: Fernando Valenzuela, 1981
Amid the euphoria in Los Angeles that became known as "Fernandomania," Valenzuela tossed seven complete games -- including five shutouts -- in his first eight career starts.

No. 14: Greg Maddux, 1995
Perhaps the best starting pitcher of the '90s and the anchor of the best starting rotation of the decade, Maddux had an incredible campaign in the middle of the Braves' amazing run. Maddux was brilliant in helping to lead the organization to its first World Series title since moving to Atlanta, as he posted a 1.63 ERA and 0.81 WHIP in 28 starts. He walked only 23 of the 785 batters he faced.
No. 13: Mickey Mantle, 1956

No. 10: Randy Johnson, 2001
Few pitchers in baseball history have had as overpowering a season on the mound as the Big Unit did, as he helped lead the D-backs to a World Series title. Johnson posted a 2.49 ERA and struck out 372 batters (13.4 strikeouts per nine innings). He won his third consecutive NL Cy Young Award and was named co-MVP of the World Series with Curt Schilling.

No. 8: Ted Williams, 1941
"The Splendid Splinter" remains the last player to hit .400 or better in a season, as he finished the '41 campaign with a .406 mark. At just 22 years old, Williams' OBP was .553 and he slugged .735 with 37 homers, as Williams capped one of the greatest offensive seasons in MLB history. His 235 OPS+ is tied for eighth-highest all-time.

Hershiser's phenomenal season was highlighted by an MLB-record 59 consecutive scoreless innings. The Dodgers right-hander posted a 2.26 ERA and logged 15 complete games -- including eight shutouts. He won the NL Cy Young Award and also went on to be named MVP of the NL Championship Series and World Series.
No. 6: Sandy Koufax, 1965
In the midst of a five-season stretch that is among the greatest ever put together by a starting pitcher, Koufax posted a 2.04 ERA in 43 games (41 starts) -- including 27 complete games and eight shutouts. He struck out 382 batters in 335 2/3 innings and won the second of three career NL Cy Young Awards. He also won his second World Series MVP Award with a 0.38 ERA in three starts against the Twins.
No. 5: Joe DiMaggio, 1941
DiMaggio set a record that stands to this day -- and which no one has come close to matching -- as he hit safely in 56 consecutive games. While Williams hit .406 for the season, it was DiMaggio who was named AL MVP, as he slashed .357/.440/.643 with 30 homers for the Yankees.
No. 4: Pedro Martinez, 1999
Martinez posted a career-high 13.2 strikeouts per nine innings and a 2.07 ERA in '99, in the midst of one of the highest run-scoring eras in baseball history, as he surrendered only nine home runs in 213 1/3 innings. During the All-Star Game at Fenway Park, he struck out the first four NL batters he faced -- Barry Larkin, Larry Walker, Sosa and McGwire. He also won the second of three career Cy Young Awards.
No. 3: Jackie Robinson, 1947
Under the enormous pressure of being the player who broke baseball's color barrier, Robinson won the NL Rookie of the Year Award and helped the Brooklyn Dodgers reach the World Series. He slashed .297/.383/.427 with 12 home runs and 29 stolen bases -- which included four steals of home.
No. 2: Bob Gibson, 1968
Gibson's 1.12 ERA over 34 starts is the lowest single-season ERA since Dutch Leonard's 0.96 in '14. The intimidating right-hander was utterly overpowering, as he tossed 28 complete games -- including 13 shutouts. In the World Series that year, Gibson had a 1.67 ERA and 35 strikeouts in three starts. He won the NL Cy Young Award and NL MVP.
No. 1: Barry Bonds, 2004
Bonds walked an astounding 232 times, of which 120 were of the intentional variety. It spoke volumes about just how feared he was as a slugger, and it played a large part in his MLB-record .609 on-base percentage. Bonds still hit 45 home runs, while slugging .812 -- the fourth-highest single-season slugging percentage of all time.
