2. Ken Griffey Sr. and Jr.

Sport: Baseball     The father was a fleet, hard-hitting outfielder for the Big Red Machine. The son is a fleet, hard-hitting outfielder who has joined the same team thanks to a blockbuster trade with Seattle. Senior has two world championships with the 1975-76 Cincinnati Reds, a modern-era team matched only by the 1998-99 New York Yankees for overall superiority and dominance. Junior has no world championships, but is a world-class act, the best all-around player in baseball. While Senior was an above-average hitter, fielder and baserunner. Junior is baseball’s best outfielder, a smart baserunner who could steal more bases if he had to, and a slugger whose home run totals would be startling if it wasn’t for Mark McGwire and Sammy Sosa. Still, Junior is the one Hank Aaron designated as the player most likely to surpass his career home run record of 755. If Junior, age 29, averages a modest 36 homers a season for the next 10 years, Aaron’s cherished record be his. Will the father be forgotten in the son’s run for immortality? Hardly. Senior may very well be Junior’s manager for the historic chase.
