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.

I would have to say Josh Gibson with his 986 Home Runs hitting a whooping 0 in the major leagues and 986 in the negro leagues.

Babe Ruth is your Radio Sports Trivia Answer\n\n"How to hit home runs: I swing as hard as I can, and I try to swing right through the ball...The harder you grip the bat, the more you can swing it through the ball, and the farther the ball will go. I swing big, with everything I've got. I hit big or I miss big. I like to live as big as I can."\nhttp://baseball-almanac.com/quotes/quoruth.shtml

Correct the record in the past had been 37 home runs in a single day and on April 13th that changed to 48 homeruns thanks to juiced balls. Hey if you can't juice the player why not juice the ball right?

Game 3 ALCS 2004?\n\nFrom that point on the Yankees were in control, setting a team record for postseason runs scored. The two teams combined for 37 hits and 20 extra-base hits, both postseason records, and at four hours and twenty minutes, it was the longest nine-inning postseason game ever played. Hideki Matsui had five hits and five RBIs, tying LCS records. Along with Alex Rodríguez, he tied the postseason record for runs scored with five.

I don't have an answer, but let me rephrase your question so it's coherent:\n\n"What player hit two home runs in a single inning, one as a left handed batter and one right handed?"

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

I'm sure somebody in the history of the game has grounded into a double play in their only Major League at-bat, so whoever that is would be your answer.

It was Jeffey Leonard of the San Francisco Giants vs the St Louis Cardinals. This from a guy who hit only 17 HR for the season.

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.
