The Nationals will aim to stay perfect at Citi Field in 2014 on Thursday night in the series finale against the Mets.
Washington is 5-0 in New York this season, but its success at the Mets' ballpark has not been limited to the past five months. Since June 28, 2013, the Nationals -- who maintained a five-game lead in the National League East with a 3-2 win Wednesday night -- are 11-1 at Citi Field, including a 10-win streak and two series sweeps. A win Thursday would make it three.
Right-hander Stephen Strasburg will look to continue the Nationals' success when he takes the mound against Mets starter Dillon Gee.
Strasburg is coming off a putrid outing in which he surrendered seven earned runs on seven hits, including four home runs, in a 7-6 loss to the Braves.
"I just didn't execute pitches when I needed to," said Strasburg, who is 8-10 with a 3.68 ERA on the season.
Gee, meanwhile, returned to his first-half form his last time out against the Phillies on Saturday. He spun seven innings of one-run ball and only surrendered three hits.
It was the right-hander's first quality start since July 9, when he made his first appearance since returning from the disabled list after missing nearly a month because of a strained right lat.
"I was really, really impressed," Mets manager Terry Collins said of Gee's performance. "I was extremely happy for him, because we need him. We need to see what he was giving us in the first half -- that first two months, anyway. If he gets back, that's really going to make a difference right now."
Nationals: Werth sidelined with AC joint sprain
Right fielder Jayson Werth underwent an MRI on his injured right shoulder Tuesday night, and the results revealed an AC joint sprain. He received a cortisone shot in the shoulder on Wednesday and will not be available for the at least the next couple of days.
Werth hurt the shoulder making a catch against the Phillies last week at Nationals Park. The right-handed slugger has been out of the starting lineup in three of the past four games.
"He should be good to go [in a couple of days]. It's one of those things where it's kind of a painful thing," manager Matt Williams said. "There is no structural damage, no issues or anything else in the pictures. The cortisone shot will calm it down to get the inflammation out of there as quickly as possible. But during the process, he can't play. He has to shut it down for a couple of days at least."
Mets: Torres tipping pitches?
After Nationals outfielder Michael Taylor shot a fastball over the right-field wall Tuesday night for his first home run in the Majors, the chatter in the Mets dugout wasn't about Taylor's impressive big league debut. Instead, they wondered whether reliever Carlos Torres has been tipping his pitches.
Tuesday marked the fourth consecutive outing -- and the sixth time in his last eight games -- in which Torres has yielded a long ball. Torres' ERA has risen to 3.76 from 2.88 in that span, and he now leads all Mets relievers in home runs allowed (10). His last three outings have all been against the Nationals.
"Location, location, location. There's not much else to say," Collins said. "This guy has really pitched well, and right now he's making mistakes in the middle of the plate. As a matter of fact, we talked in the dugout about possibly maybe he's tipping somehow, because he's getting hit way too hard."
Torres, though, seemed confident that was not the case. He believes he's discovered the issue, but for now he wants to stay mum on the specifics.
"I'm not going to share. I have very strong suspicions as to why [I've struggled]," Torres said "Nothing to do with tipping pitches."
• Nationals center fielder Denard Span's 36-game on-base streak ended Tuesday night when he went 0-for-5 with a strikeout in the team's 7-1 victory over the Mets. Span was out of the starting lineup on Wednesday but entered the game in the bottom of the eighth inning for Kevin Frandsen.
• Mets starter Matt Harvey threw 27 pitches from a mound Wednesday in Port St. Lucie, Fla., during his continued rehab from Tommy John surgery.
