As Sammy Sosa is no longer being considered for the list of players eligible for the Major League Baseball Hall of Famers at Cooperstown, hopes are high that Dominican pitcher Pedro Martinez may be the next to join San Francisco Giants pitcher Juan Marichal when the vote takes place in 2015. Sosa is the only player in MLB history with three seasons of 60 or more homeruns. However, the steroid controversy scandal tainted Sosa’s possibilities, as happened to Barry Bonds and Roger Clemens who had the numbers to reach Cooperstown in 2013 during their first year of eligibility.
The Hall of Fame future eligible list for 2015 includes Martinez and his brother Ramon. Players who are eligible have played 10 seasons of Major League Baseball and have been retired from for five full seasons.
