Cliff Lee tossed seven sharp innings to earn his first home win in nearly a year and the Philadelphia Phillies completed a three-game sweep against the major league-leading Washington Nationals with a 4-1 victory on Sunday.

Jimmy Rollins hit a two-run homer and Laynce Nix had a solo shot to back Lee (3-7). The 2008 AL Cy Young Award winner hadn't won at Citizens Bank Park since September 5, going 0-6 in his previous 12 starts.

Lee outpitched Jordan Zimmerman (9-8) by allowing one run and seven hits, striking out five. Jeremy Horst got an out in the eighth and Josh Lindblom got the last five outs for his first career save. Jonathan Papelbon had the day off after closing three straight games.
