The Pirates and Athletics, both rebuilding, open a series with key pitchers and power-hitting highlights.

The Pittsburgh Pirates and Oakland Athletics, both having underwhelming seasons, are focusing on the future as they prepare for the next MLB season. The Pirates gave first baseman Rafael Flores, acquired from the Yankees, his major league debut, where he went 1-for-3 with a walk in an 8-4 loss to the Cubs. The teams are set to open a three-game series in Pittsburgh, with Mitch Keller and Luis Severino scheduled to start for the Pirates and Athletics, respectively. The Athletics have stood out this season with their power hitting, becoming the second MLB team with three players—Brent Rooker, Nick Kurtz, and Shea Langeliers—each hitting at least 30 home runs.
