Travis Wood didn't finish 2013 with a 0.00 ERA, so he isn't happy just yet.
Wood, the Cubs' lone All-Star last year, refuses to get complacent.

"Just take it and run with it. Continue to take the ball every fifth day and do everything I can to give them a chance to win and get deep into ballgames," Wood said in an interview with CSN's Kelly Crull.
"You always have something to work on, whether it's pitch selection or pitch efficiency. Until you have a 0.00 ERA at the end of the year, you always have something to work on."

Wood was acquired by the Cubs in the deal that sent left-handed reliever Sean Marshall to the Cincinnati Reds before the 2012 season.
Wood, who turned 27 Thursday, was 9-12 last season with a 3.11 ERA and 1.15 WHIP in 200 innings over 32 games started.
