Pittsburgh Pirates (16-14) visit Arizona Diamondbacks (15-13) for a three-game series opener at Chase Field on May 5, with both NL contenders mired around .500 amid the Pirates' season-high four-game losing streak against the Cardinals and Brewers. Probable starters Bubba Chandler (PIT) face veteran lefty Eduardo Rodriguez (ARI), while Diamondbacks ace Zac Gallen remains day-to-day with a right shoulder contusion from April 25 but is slated for a bullpen session and next turn. Key absences include Pirates INF Jared Triolo (knee, out until late May) and D-backs catcher Gabriel Moreno (oblique, 10-day IL); Arizona holds an 11-9 edge in the last 20 head-to-heads, bolstered by home-field hitter-friendly confines and recent 5-5 form.
