MLB free agency can be described as one of the most exciting times in sports as players make their decisions on their next destination. Here is a list of the biggest free agent signings in MLB history. Barry Bonds' six-year, $43.8 million contract with the San Francisco Giants is considered one of, if not the greatest, free agent deals in MLB history. In his first six seasons with the Giants, Bonds won an MVP, posting 307/.445/.617 splits and hitting 235 home runs before going on to collect a further four MVPs later in his stint in San Francisco. Randy Johnson signed a four-year deal with the Arizona Diamondbacks in 1999 before going on to capture four straight Cy Young Awards and winning a World Series title. Fellow pitcher Greg Maddux signed with the Atlanta Braves in 1993, where he went on to capture three Cy Young Awards, one championship and a National League title. Despite playing just two years with the Toronto Blue Jays, Roger Clemens registered a 10.1 WAR and received two Cy Young Awards in the process. Reggie Jackson spent four years with the New York Yankees from 1977 to 1981, helping the team to win two titles across three trips to the World Series.
