Two-way stars are rare because it's hard enough to get to the big leagues and even harder to excel as either a hitter or a pitcher, let alone both. But the Rangers will try to beat the odds with not one but two prospects who made brief pro debuts last year. They're going to simultaneously develop Seong-Jun Kim (No. 15, signed out of Korea for $1.2 million last May) and Josh Owens (No. 6, a third-round pick from a Tennessee high school in July) as both shortstops and right-handers.
