Nick Martinez is scheduled to start Friday night, though Texas Rangers fans are more eagerly anticipating who could follow him. The trade speculation has made Martinez's outing a bit of an afterthought as the Rangers welcome the San Francisco Giants to Arlington for the first time since the 2010 World Series for this three-game set. Texas (49-52) is close to finalizing a deal with Philadelphia to acquire Hamels and reliever Jake Diekman for left-hander Matt Harrison and a package of top prospects.
