NEW YORK -- Cliff Lee allowed just five hits in eight innings Monday night and Cody Asche hit a two-run triple in the fourth inning to lift the Philadelphia Phillies to a 2-1 win over the New York Mets in front of 25,784 at Citi Field.
The Phillies (60-71) won for the fifth time in their past six games and improved to 7-4 since Ryne Sandberg replaced Charlie Manuel as manager.
The win also gave the Phillies sole possession of third place in the NL East over the Mets (58-71), who lost their fifth straight game just hours after learning that staff ace Matt Harvey is done for the year -- and is likely headed for Tommy John surgery on his right elbow -- with a slight tear of the ulnar collateral ligament in his right elbow.
Harvey complained of forearm soreness Saturday after he allowed a career-high 13 hits in 6 2/3 innings in the Mets' 3-0 loss to the Tigers. He visited Mets physician Dr. David Altchek on Monday and an MRI revealed the injury.
Mets general manager Sandy Alderson said Harvey would undergo another MRI in about 10 days, after the swelling has gone down, and that it's possible the injury won't require surgery. Harvey said he hoped he could rehab the injury without surgery and pitch next season.
But many pitchers who pitch with partial ligament tears eventually suffer a complete tear. The Dodgers' Chad Billingsley suffered a partial tear last August and tried to rehab it without surgery, but underwent the procedure after making just two starts in April.
Regardless of how Harvey chooses to rehab the injury, his brilliant breakout season -- one in which he gave frustrated Mets fans reason to believe brighter days were ahead -- is over.
Harvey, who started for the National League in the All-Star Game at Citi Field, went 9-5 with a 2.27 ERA and a National League-high 191 strikeouts in 178 1/3 innings. He carried a no-hitter into the seventh inning in three starts and authored one of the finest games in team history on May 7, when he allowed one hit -- an infield single -- and walked none while striking out 12 in nine innings in the Mets' 1-0, 10-inning win over the White Sox.
The Mets had staked their hopes for 2014 and beyond on Harvey and Zack Wheeler, the latter of whom was outdueled by Lee on Monday despite throwing 6 2/3 solid innings. Wheeler allowed the two runs on five hits and one walk and struck out seven.
In a possible sign of the extreme caution with which the Mets will treat him following Harvey's injury, Wheeler was lifted at 105 pitches -- a total he'd exceeded in five of his first 12 big league starts, including his last three -- even though Lee was due up.
Lee set down 18 of 19 batters after Andrew Brown's second-inning RBI single, including 11 in a row between the fourth and eighth, before the Mets put two runners on in the eighth. But he struck out Juan Lagares with his 121st pitch of the night to preserve the lead.
Jonathan Papelbon earned his 22nd save with a perfect ninth inning.
Lee finished with seven strikeouts and one walk -- the 16th time in 25 starts this year that he's walked one batter or less.
Asche and Michael Young each had two hits for the Phillies.
Marlon Byrd had two hits for the Mets.
NOTES: RHP Carlos Torres will replace Harvey in the rotation and is scheduled to start the finale of the four-game series against the Phillies on Thursday. ... The Mets received more bad pitching news Monday. ESPNNewYork.com reported that RHP Jeremy Hefner, who was diagnosed with a partially torn medial collateral ligament in his right elbow, likely will undergo Tommy John surgery. Altchek recommended surgery for Hefner after meeting with him last week. ... Phillies OF Casper Wells was placed on the 15-day disabled list due to vision problems. Wells underwent LASIK surgery last November but has continued to have vision issues. He is hitting .128 in 94 at-bats this season between the Phillies, Chicago White Sox and Oakland A's. He also pitched for the second time this season Saturday, when he took the loss after allowing five runs in the 18th inning against the Arizona Diamondbacks. ...
