WASHINGTON (AP) - Adam Morgan gave the Philadelphia Phillies another quality start. But once again, the lowest-scoring team in the majors didn't give him a lot of support.
Gio Gonzalez pitched seven sharp innings, Anthony Rendon doubled home the tiebreaking run and the NL East-leading Washington Nationals defeated the Phillies 3-2 on Sunday.
Tommy Joseph homered in the seventh to snap Philadelphia's 16-inning scoreless drought and Freddy Galvis homered in the eighth.
"These four games remind me of earlier in the season when we'd come back and win these games," Phillies manager Pete Mackanin said. "But right now we're not winning these games and the offense has sputtered."
The Phillies are batting .187 in their last 16 contests with only one double-digit hit game, and have scored a total of 41 runs in that span. Philadelphia has scored 520 runs this season -- that's 30 fewer than Atlanta, the next-to-last team.
"The pitchers are doing a really good job," said Galvis, "but we as the hitters have to step up a little bit, make something happen and get some runs for those guys. They've been throwing the ball good."
During the four-game series in Washington, Phillies starters threw 23 1/3 innings, allowing 15 hits and four runs.
Morgan (2-10) was the latest to impress with his third straight quality start. The left-hander allowed two runs on three hits over six innings plus one batter.
Morgan has allowed two earned runs or fewer in five of his last six outings and credits his recent success to mixing his pitches better.
"That's the name of the game, changing speeds and keeping guys from cheating," Morgan said. "I'm just going to keep throwing like I've been throwing."
Gonzalez (11-9) gave up one run and five hits over seven innings, striking out five with one walk. Mark Melancon pitched a scoreless ninth for his 41st save of the season.
Washington turned three double plays, including in the eighth inning when the Phillies had runners on first and second with one out.
