The Rangers are more focused on trading for a starting pitcher than signing free-agent first baseman Prince Fielder or Japanese right-hander Yu Darvish, according to sources. The team's payroll flexibility, sources say, is not as significant as many previously believed. Thus, Texas is exploring more cost-effective moves for pitchers such as Cubs right-hander Matt Garza, Athletics lefty Gio Gonzalez and Rays righty Wade Davis.
