During the Nationals′ three seasons there, RFK then became known as a pitchers' park. While Frank Howard hit at least 44 home runs for three straight seasons at RFK for the second Washington Senators franchise from 1968 through 1970, the 2005 Nationals had only one-hitter with more than 15 home runs, José Guillén with 24. However, in his lone season with the team in 2006, Alfonso Soriano hit 46 home runs.
