The A's beat the Pirates 4-3, but Zack Gelof will miss the rest of the season with a shoulder injury.

The Oakland Athletics, seeking a series win, sent rookie Luis Morales (4-1, 3.08 ERA) to pitch against the Pirates' rookie Bubba Chandler (2-1, 5.66 ERA), known for his high-velocity fastball. The A's, tied for fourth in MLB with 214 home runs, won the opener 4-3, powered by home runs from Nick Kurtz and Lawrence Butler. Despite an aggressive approach that sometimes leads to early outs, the team remains confident in its fastball-focused offense. However, they face a setback as second baseman Zack Gelof will miss the rest of the season after dislocating his left shoulder.
