"I think every day I get better and better and I think [it will be] less than that," he said. "I'm very optimistic [about coming back this year]."
Furcal strained his hamstring on June 21 when he tried to leg out a double-play grounder in the third inning against the Mets.
Furcal missed the first two months of the season with a different hamstring injury that he sustained in Spring Training and a groin strain suffered during his rehab. He finally made his Marlins debut on June 13 and ended up starting in eight games before hurting himself again.
"It's tough for me," Furcal said. "[I did] a lot of exercise, I get it strong, and then when I get to Spring Training, I was feeling good. Then that happened and it was very frustrating.
"I'm very positive. I hope [I'll be back]."
