San Diego Padres at Arizona Diamondbacks (2026-08-04). Randy Vásquez vs Eduardo Rodriguez at Chase Field.
Starters — Randy Vásquez has a 4.45 ERA and 1.47 WHIP across 95 innings, with 6.06 K/9, 2.84 BB/9, and 1.33 HR/9. His last three starts were uneven: 4.2 innings with 0 earned runs, then 2.2 innings with 1 earned run, then 0.2 innings with 2 earned runs. The recent line suggests limited length and a downward trend despite the scoreless outing last time. Eduardo Rodriguez has been far steadier, carrying a 2.48 ERA and 1.21 WHIP over 130.2 innings, with 6.06 K/9, 3.1 BB/9, and 0.9 HR/9. In his last three starts, he threw 8 scoreless innings, then 6 innings with 2 earned runs, before a rough 2.2-inning, 5-earned-run outing. The broader profile remains strong, and his home run suppression stands out even with a listed downward trend.
Teams — San Diego enters with a .694 OPS, 473 runs scored, a .235 team average, and a pitching staff at 4.15 ERA with a 1.33 WHIP. The Padres are also 8-2 over their last 10 games, which points to improved current form even though the season-long offense has been more modest. Arizona owns a slightly better .706 OPS, has scored 513 runs, and is batting .242 as a team. The Diamondbacks’ staff has a 4.18 ERA and 1.29 WHIP, and they are 6-4 in their last 10. Arizona has the stronger season-long offensive output, while San Diego brings the hotter recent stretch.
