Martinez (leg) is expected to be back in the Tigers' lineup Sunday, MLive's Chris Iott reports. "I think he'll be fine," manager Brad Ausmus said. "As a matter of fact, I'd be surprised if he doesn't play (Sunday). It just kind of grabbed him on one swing. He really took a hellacious hack and it kind of grabbed him, but it calmed down pretty quickly and we don't think it's anything serious." He felt a slight pinch in his surgically repaired right knee cap and then hit a single and was replaced with a pinch runner Saturday, but it does not sound like a major issue at this point. Perhaps more pressing is the fact that Martinez will get three days off when the Tigers travel to Pittsburgh for a series that starts Monday. This makes him a difficult play in weekly leagues, but it should also give him a chance to rest his knee.
