While they managed a single win against the Boston Red Sox,[80] it was followed by a six-game losing streak wherein the Phillies were swept by the Toronto Blue Jays and the Baltimore Orioles;[81] Philadelphia was outscored 38–19 over the two series.
During the series, the team's 2009 All-Stars were announced: Utley and Ibáñez were elected as starters, and Howard was named as a reserve, one of four first basemen selected to the National League squad.
[89] Though closer Lidge suffered a tough loss on July 7, sacrificing a run in the ninth inning to earn his fourth of the season, the Phillies bounced back with a dramatic ninth-inning win the following night.

[110] It became the first win of a three-game series sweep,[111] which Lee closed out with a third straight dominant performance (eight innings pitched, one run allowed, eight strikeouts).

[122] The Phillies opened the month by taking two of a three-game series against the Giants, besting Jonathan Sánchez, who threw a no-hitter earlier in the 2009 season,[123] and Tim Lincecum, who won the 2008 NL Cy Young Award.
[125] The Phillies offense backed Lee to his sixth win the following night, with Madson earning his second consecutive save after assuming the de facto closer's role from Lidge.
[131] Hamels closed out the series with a strong performance, perfect through his first five innings and finishing with one run allowed in eight; with their 15th win over the Nationals, the Phillies matched their best season record against the franchise, set against the 1976 Montréal Expos.
In the rubber game, Lidge blew his 11th save after a rain delay to give the Marlins a series victory, keeping the team's number to clinch the division at five.
Cliff Lee pitched a complete game in the opener of the series, shutting out the Rockies through 8+2⁄3 innings before allowing a single run in the ninth.

[171] After the strikeout, Marte was relieved by Rivera in a non-save situation, who allowed one hit and one walk before closing out the game and the Yankees' 27th championship.
