When Span returned to the Nationals earlier this week, he said he didn't feel that great at all.
"After the second game [against the Padres], I went home," Span said. "I wasn't feeling good. I had two hits. Normally when I get two hits, I'm in an upbeat mood. I just wasn't. So I talked to my mom and I thought [having surgery] was best for my future. I need to go ahead and get myself fixed so I can be myself on the field."
Span said he's had a terrible eight months. He had hernia and abdominal surgery before the regular season started. He hasn't fully recovered from the abdominal surgery. Then he had back spasms that put him on the disabled list on July 7.
"It's been a domino effect -- bad timing, bad luck," Span said. "It's just frustrating, but I'm trying to stay positive as much as possible and try to trust in God's plan that I will overcome this. It's just another chapter in my book. It's all I can do right now."
Span's latest injury comes at a bad time. He is a free agent after the season and the Nationals are still in the National League East race, entering Saturday 6 1/2 games behind the first-place Mets.
"It was a tough decision trying to come back and also shutting it down," Span said. "All around, it's tough. I worked my butt off to get to this point. I have to wait and get myself better. I'm fine with waiting."
Span has been a tremendous leadoff hitter during his time in Washington, hitting .292 with a .345 on-base percentage in three years with the club. Span believes the trade that sent him from the Twins to the Nationals for right-hander Alex Meyer after the 2012 season resurrected his career. Span went so far as to say the Nats elevated his game.
"I enjoyed my three years here," Span said. "This trade was probably the best thing for me at the time. I learned a lot here from the coaching staff, my teammates. It's been a good time."
