CSN Bay Area suggests Barry Zito's rotation spot could be in jeopardy. Zito has struggled mightily on the road this season and currently owns a 4.88 ERA over his first 19 starts. The Giants don't have any obvious candidates to replace him, so he'll remain in the starting rotation for now. If Zito doesn't improve in the second half, he could be moved to the bullpen when Ryan Vogelsong returns from the disabled list.
