Haren talked about his struggles this season, stating:
"I haven't lived up to what I was paid to do and what I came here to accomplish, despite the last two or three weeks. The majority of the season has been a struggle for me. Even if I wanted to come back - it has been a tough year. I haven't lived up to the billing so far. I don't know what next year is going to bring."
The Nationals signed Haren to a one-year, $13 million contract in the offseason, but the right-hander has had a difficult year, going 6-11 with a 5.14 ERA over 20 starts.
The starter spent some time on the disabled list with shoulder stiffness and has performed better since his return, going 2-2 with a 2.40 ERA and 32 strikeouts in 30 innings.
Haren's family may impact his decision on where he pitches next season; Haren admitted to Ladson that he misses his wife and two kids, who live in Southern California:
"I know the fans don't care. But we're humans, too. I have two little kids and I see them once every month and a half or so. It has been really hard. I've been fortunate to play on the West Coast just by being traded to a couple of teams. I would be close to home."
Washington has had a disappointing season, entering Monday with a 54-57 record, 12 1/2 games behind the Atlanta Braves in the NL East.
