Geraldo Perdomo hit a grand slam Wednesday night and Brandon Pfaadt sailed through the longest start of his career as the visiting Arizona Diamondbacks cruised to an 8-2 win over the San Diego Padres.

Brandon Pfaadt continued the streak of very good performances from the Diamondbacks' starting rotation on Wednesday in San Diego.

Darvish was well past his prime when the Padres got him, yet has avoided a serious arm injury in his Padres tenure. Similarly, Snell suffered no alarming setbacks — certainly nothing comparable to the shoulder ailment that has sidelined the Dodgers’ $180-million winter addition for most of this season.

Right-hander Dylan Cease has not had excellent results in 2025, but his underlying metrics are those of a much sturdier arm. His 4.62 ERA is bolstered by a 3.40 FIP and 3.52 expected ERA. He's still striking out north of 11 batters per nine innings and his stuff has remained impressive.

BOTTOM LINE: The Arizona Diamondbacks meet the San Diego Padres with a 1-0 series lead. San Diego has gone 27-16 in home games and 48-42 overall. The Padres have the ninth-ranked team batting average in the NL at .246.
