After his third straight start surrendering four or more earned runs Tuesday, Phillies starter A.J. Burnett was asked if he expects to be on the field next season.
The right-hander's response was not convincing.
"I have no idea," said Burnett, who will take the mound Monday in the series opener against the Nationals at Citizens Bank Park. "Probably not."
The 37-year-old veteran hinted at retirement during the offseason but ultimately signed a one-year deal with Philadelphia worth $16 million. That contract includes an option for 2015 that reached $10 million after Burnett's 27th start Tuesday. The amount would increase to $11.75 million after his 30th start and $12.75 million after his 32nd start.
If the Phillies stick to a five-man rotation, Burnett is on pace to make 34 starts. The right-hander is 6-14 with a 4.42 ERA on the season.
"I'm not making pitches when I need to make pitches," Burnett said.
Burnett will face off against Nationals starter Tanner Roark on Monday. The right-hander will look to build on Washington's eight-game lead in the National League East, which marks a season high.
Roark is 12-7 with a 2.80 ERA in 2014. He dealt seven innings of scoreless ball against the D-backs on Wednesday but earned a no-decision. It was his first time surrendering no runs in an outing since June 6.
"I felt good," Roark said after the start. "The first two innings, I was nibbling a little with my fastball and then I just started attacking more and being more aggressive.
Phillies: Adams set to begin rehab stint at Triple-A
There's still a chance Mike Adams will pitch for the Phillies again this season. The reliever is scheduled to begin a Minor League rehab assignment Tuesday with Triple-A Lehigh Valley.
Adams has been on the disabled list since June 7 due to inflammation in his right rotator cuff. He had a 2.12 ERA in 19 appearances before the injury. Adams has been working out at the club's Spring Training complex in Clearwater, Fla., and will join the Phils on Monday for a workout at Citizens Bank Park before going to Lehigh Valley.
Phillies manager Ryne Sandberg said he's been surprised "in some regards" by Adams' recovery.
"He was in Florida doing his throwing program and progressed rather quickly, I would say in the last week or so, to actually get him to joining Lehigh Valley," Sandberg said.
Adams is in the final year of a two-year, $12 million contract. He has a $6 million club option for 2015 that vests automatically if he throws 60 innings this season. The option jumps to $6.5 million if he throws 120 innings in 2013-14. Neither will happen. He has worked 42 innings over the past two seasons, including 17 innings this year.
Nationals: Schierholtz makes debut
Nate Schierholtz made his debut for the Nationals in Sunday's series finale against the Giants.
The outfielder represented the tying run when he came to the plate as a pinch-hitter in the fourth inning with runners on first and second after San Francisco shelled Stephen Strasburg for five runs. However, Schierholtz popped up to short to end the threat in his first at-bat in Washington.
The Nationals signed Schierholtz to a Minor League contract Monday. He went 3-for-19 with a home run and four RBIs in four games with Triple-A Syracuse before joining the big league squad Saturday.
• After a come-from-behind victory over the Giants on Sunday afternoon, the Nationals have won 12 of their last 13 games.
• The Phillies will recognize the Taney Dragons Little League World Series team Wednesday with a pregame ceremony and celebration. All fans in attendance will receive a Taney Dragons T-shirt.
