Rapid Reaction: Phillies 2, Mets 1

NEW YORK -- The worst day of the Mets' season didn't get any better at night.

After it was announced that ace Matt Harvey has a partially torn UCL in his pitching elbow, the Mets fell to the Phillies 2-1 on Monday night at Citi Field.

Zack Wheeler was outpitched by All-Star Cliff Lee.

Just needed one out: Wheeler's inability to close out the fourth inning cost him the game. With two outs in the fourth, and the Mets ahead 1-0, he allowed a single to Michael Young and walked Darin Ruf, the lone free pass he yielded. Cody Asche then drilled a two-run triple to deep right-center to put the Phillies ahead 2-1. Aside from that trouble, Wheeler otherwise cruised against this weak lineup, giving up just five hits in 6 2/3 innings. He struck out seven and was charged with just those two runs over 105 pitches. He fell to 6-3.

Much different: The last time Lee faced the Mets, he got tagged with the loss on July 21 after surrendering five runs and seven hits in six innings. Lee dominated the Mets on Monday and possibly could have had a scoreless outing if not for a blunder by his outfielders. A routine fly ball to right-center dropped in between right fielder John Mayberry Jr. and center fielder Roger Bernadina in the second inning. Marlon Byrd, who was credited with a double, came around to score on a single by Andrew Brown that put the Mets up 1-0. Lee went eight innings.

First time: Top prospect Travis d'Arnaud caught a runner stealing for the first time in his career as he nailed Chase Utley at second for a pivotal out in the eighth inning. He went 1-for-3 with a single in the eighth inning.

Up next: The Mets will try to end their five-game slide as Jon Niese (5-6, 4.03 ERA) faces off against Kyle Kendrick (10-10, 4.51) at 7:10 p.m.
