Question: Up for Grabs is a 2004 comedic documentary about a home run ball hit by a player born in what year?

Context paragraphs:
At bats per home run: In baseball statistics, at bats per home run (AB/HR) is a way to measure how frequently a batter hits a home run.  It is determined by dividing the number of at bats by the number of home runs hit.  Mark McGwire possesses the MLB record for this statistic with a career ratio of 10.61 at bats per home run and Babe Ruth is second, with 11.76 at bats per home run.  Giancarlo Stanton, with 14.33 at bats per home run, currently holds the record among active players.

Babe Ruth's called shot: Babe Ruth's called shot was the home run hit by Babe Ruth of the New York Yankees in the fifth inning of Game 3 of the 1932 World Series, held on October 1, 1932, at Wrigley Field in Chicago.  During the at-bat, Ruth made a pointing gesture, which existing film confirms, but the exact meaning of his gesture remains ambiguous.  Although neither fully confirmed nor refuted, the story goes that Ruth pointed to the center-field bleachers during the at-bat.  It was allegedly a declaration that he would hit a home run to this part of the park.  On the next pitch, Ruth hit a home run to center field.  The home run was his fifteenth, and last, in his 41 post-season games.  It was said to be one of the greatest home runs in history.

Up for Grabs (film): Up for Grabs is a 2004 comedic documentary about two men who fought over custody of a baseball.  It is based on a real-life incident surrounding a record-setting Barry Bonds homerun, where the ball was contested in the property law case of "Popov v. Hayashi".  It was directed and produced by Michael Wranovics.

Chinese home run: In baseball, a Chinese home run, also a Chinese homer, Harlem home run, or Pekinese poke, is a derogatory and archaic term for a hit that just barely clears the outfield fence at its closest distance to home plate, essentially the shortest home run possible in the ballpark in question, particularly if the park is known to have an atypically short fence to begin with.  The term was most commonly used in reference to home runs hit along the right field foul line at the Polo Grounds, home of the New York Giants, where that distance was short even by contemporary standards.  When the Giants moved to San Francisco in 1958, the Los Angeles Coliseum, temporary home of the newly relocated Los Angeles Dodgers, took over the reputation for four seasons until the team took up residence in its permanent home at Dodger Stadium in 1962.  Following two seasons of use by the expansion New York Mets in the early 1960s, the Polo Grounds were demolished, and the term gradually dropped out of use.

Inside-the-park home run: In baseball, an inside-the-park home run is a play where a batter hits a home run without hitting the ball out of the field of play.  It is also known as an "in-the-park home run" or "in the park homer".  It goes on the batter's record as a hit.

50 home run club: In Major League Baseball (MLB), the 50 home run club is the group of batters who have hit 50 or more home runs in a single season.  Babe Ruth was the first to achieve this, doing so in 1920.  By reaching the milestone, he also became the first player to hit 30 and then 40 home runs in a single-season, breaking his own record of 29 from the 1919 season.  Ruth subsequently became the first player to reach the 50 home run club on four occasions, repeating the achievement in 1921, 1927 and 1928.  He remained the only player to accomplish this until Mark McGwire and Sammy Sosa matched his feat in 1999 and 2001, respectively, thus becoming the only players to achieve four consecutive 50 home run seasons.  Barry Bonds hit the most home runs to join the club, collecting 73 in 2001.  The most recent player to reach the milestone is Aaron Judge, achieving the feat during the 2017 season.

Home Run Battle 3D: Home Run Battle 3D (originally Baseball Slugger: Home Run Race 3D) is an arcade-style, Home Run Derby video game developed by Com2uS for mobile phones.  It was inducted into Apple's first App Hall of Fame on October 10, 2010.  Home Run Battle 3D is notable for its use of costumes to enhance player attributes, though critics have accused it as a "Pay to Win" game.

2015 Major League Baseball Home Run Derby: The 2015 Major League Baseball Home Run Derby (known through sponsorship as the Gillette Home Run Derby presented by Head & Shoulders) was a home run hitting contest between eight batters from Major League Baseball (MLB).  The derby was held on July 13, 2015, at Great American Ball Park in Cincinnati, Ohio, the site of the 2015 MLB All-Star Game.

Barry Bonds: Barry Lamar Bonds (born July 24, 1964) is an American former professional baseball left fielder who played 22 seasons in Major League Baseball (MLB) with the Pittsburgh Pirates and San Francisco Giants.  Bonds received seven NL MVP awards and 14 All-Star selections, and is considered to be one of the greatest baseball players of all time.

1993 World Series: The 1993 World Series was the 90th edition of Major League Baseball's championship series and the conclusion of the 1993 Major League Baseball season.  A best-of-seven playoff series, it pitted the defending champions and American League (AL) champion Toronto Blue Jays against the National League (NL) champion Philadelphia Phillies.  With Toronto ahead three games to two in the Series, but trailing Game 6 by a score of 6-5 with one out in the bottom of the ninth inning, with runners on first and second base and a count of two balls and two strikes, Joe Carter hit a game-winning three-run home run to win Game 6 by a score of 8-6 and the series four-games-to-two for Toronto, its second consecutive championship (the first team to repeat as champions since the 1977–78 Yankees).  This was only the second Series concluded by such a home run (the first was in the 1960 World Series on a Bill Mazeroski home run for the Pittsburgh Pirates), and the first such occasion where a come-from-behind walk-off home run won a World Series.
