Jaso went 0-for-5 and has four hits in his last 34 at-bats since June 15.

EDGE Analysis

His slash line of .266/.345/.388 has dropped to its lowest level since early April. There was some thought that Pittsburgh might promote Josh Bell to serve as a DH for the 5-game swing through the American League, but that hasn't happened. Jaso, who signed a two-year, $8 million deal last winter, has surprised the team with his defense at first base. If the Pirates fall out of the playoff race, then he could become a trade piece or possibly lose playing time to Bell.
