Pittsburgh Pirates Can Win If…

  • Bubba Chandler steadies himself. After allowing nine runs in his first career start, the prized prospect needs to command the strike zone.
  • The lineup converts opportunities. Spencer Horwitz and Jared Triolo continue to hit, but Pittsburgh must cash in runners in scoring position.
  • Their bullpen holds late. Recent losses have featured breakdowns late in games; the Pirates need stability in relief.

“He’s a starting pitcher … he’ll get starts too,” manager Don Kelly said of Chandler’s future role.

Washington Nationals Can Win If…

  • Andrew Alvarez keeps rolling. With a 1.86 ERA through two starts, the rookie has shown poise on the mound.
  • The young bats stay hot. Dylan Crews, Brady House, and James Wood continue to provide extra-base power and game-changing moments.
  • Josh Bell’s September surge continues. The veteran has been on fire with 15 RBIs in his last six games.

“He does insane things I’ve never seen players do before,” Brady House said of Wood’s defensive heroics.
