In answering this question, I have 3 points to make, one that can be proven, and the other two that are speculation.\n\nJosh Gibson could abosolutely mash a baseball.  He is known to have over 900 homeruns, but the score keeping was not precise in the beginning of the negro leagues.  It is hard to say how far the balls went, but some of them were never found.\n\nMickey Mantle was a great baseball player.  The New York media fabricated the story that mantle hit this 630 ft homerun.  The Media in New York embelishes on stories because they want to be recognized and identified as the best.  The homerun in question has been personally accounted by hundreds of thousands of people that say they were there, when yankee stadium has a capacity no where near that.  The people that actually were there saw a ball hit a terrace, but homeruns werent offically and precisely measured at that time, so there is no proff only years upon years of speculating and grapevining the story about this homerum.  Every 10 or twenty years, this homerun fantasy gets longer and as this fable goes, it will eventually be a 700 ft homer.\nThe NY media blows stories like this out of proportion, and this is the result without accurate data.\n\n\nWhen playing for the Oakland Athletics, Mark Macgwire hit a Randy Johnson fastball 575 feet in Seattle when Johnson was with the Mariners.  That was proven, and measured inside a dome.

That has to be Harvey Haddix's 12 2/3 inning perfect game that was broken up in the 13th inning. Lew Burdette pitched the whole game for the Milwaukee Braves, giving up 12 hits but no runs.

Pujols.  He hit 14 homes in April, which is a new record.  Looks like there's only more to come.

Cobb by Al Stump is probably my favorite sports book. Ty Cobb, the greatest hitter ever and probably the meanest SOB to ever lace up spikes. A definite good read if you're a fan of baseball.

Mark Magwire (575) off Randy Johnson when Oakland played in Seattle.  Mickey Mantle did not hit a 630 ft homerun, that is an old wives tale.  we are not playing with golf balls and clubs here.

According to the Baseball Hall of Fame and assuming you meant any game in general, rather than only MLB, the longest game was  33 innings.\n\nSome interesting tidbits from the longest game in professional baseball history - a 33-inning marathon between the Rochester Red Wings and Pawtucket Red Sox that began on April 18, 1981 and concluded nearly two months later: \n\nExtra special: The game surpassed by four innings the previous longevity record, established by Miami and St. Petersburg of the Florida State League in 1966. \n\nTime of game: 8 hours, 25 minutes. Achy, breaky knees: Wings catcher Dave Huppert caught 31 innings. \n\nSee the link below for full details.

Q: What was the longest game ever?\n-- MaceMan26\nA: On May 8, 1984, at 7:30pm, the longest game in major-league history began. Over the course of two days and 25 grueling innings, the Milwaukee Brewers and Chicago White Sox duked it out for a record eight hours and six minutes. Both teams came within inches of victory on a few occasions, but their opponent always matched them blow-by-blow. Going into the eighth tied 1-1, Robin Yount and Ted Simmons scored for the Brew Crew. An aging Rollie Fingers could not hold the lead though, as rightfielder Charlie Moore's error opened the door for the Sox to tie it. Chicago then loaded the bases with one out in the 13th, but Marc Hill struck out and Dave Stegman fouled out to end the threat.\n\nBecause MLB rules prohibit an inning from starting after 12:59am, the game was called after the 17th and resumed the next day. Most returning fans thought the game would end quickly that next day, but instead it dragged on for another eight innings. Carlton Fisk ended an early ChiSox rally when he struck out with the bases juiced in the 18th. His failure in the clutch looked to be a crucial play, as Milwaukee tallied three runs in the 21st on Ben Oglivie's upper-deck home run. However, the resilient Sox refused to lose. Rudy Law reached on an error, Fisk redeemed himself by singling Law home, Marc Hill singled, Harold Baines walked, and Tom Paciorek singled home the tying runs. And so, the marathon continued.\n\nIn the 23rd, it was Milwaukee's turn to avoid a bullet. Chicago's Dave Stegman, who had been on first, stumbled as he tried to hold up at third after Paciorek's single was bobbled, then quickly recovered, by outfielder Rick Manning. As he lost his balance, Stegman brushed up against third base coach Jim Leyland. Since contact between coach and runner is prohibited, Stegman was called out. The next batter singled, but was later stranded. The Beer Men weren't so lucky two frames later when Baines mercifully ended the affair by jacking one over the center-field fence for a 7-6 win.\n\nTom Seaver, making his first relief appearance in eight years, got the win. He then pitched 8.1 innings in Chicago's regularly scheduled game that night, earning his second win of the day. Chuck Porter took the loss. Though it will still go down in the annals, it turned out that this game meant absolutely nothing to either team. Milwaukee and Chicago combined to finish 59 ½ games out of first place.

When Mickey Mantle cleared the left-center-field bleachers at Clark Griffith Stadium in Washington on April 17, 1953, the entire baseball world was lead to believe the ball had traveled 565 feet from home plate to the point where it landed. In truth, that figure derived from the distance from home plate to the place where a neighborhood child retrieved the ball. Since this home run was the only one that ever cleared those bleachers during decades of major league and Negro League competition, it is genuinely deserving of recognition.

September 10, 1960: In Detroit, Mickey Mantle unloads a cannon shot for three runs in the 6th inning, the ball clearing the RF roof and landing in the Brooks Lumber Yard across Trumbull Avenue. New York pins a 5–1 loss on Paul Foytack that moves them a half game in first place ahead of Baltimore, losers today. In June, 1985, Mantle's blow was retroactively measured at 643 feet, and will be listed in The Guinness Book of World Records at that distance

Roger Conner held the career record from 1895 to 1920, with 138 career home runs.  As the previous poster mentioned, Ned Williamson held the single season record, 27 in 1884, until Ruth broke it with 29 in 1919.

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.
