Padres Need More Offense Behind Buehler
The San Diego Padres enter this matchup at 25-18, but the lineup has not produced enough steady contact. San Diego is batting .222 with a .294 OBP, .365 SLG, 178 runs, 313 hits, and 41 home runs. Those numbers put pressure on the pitching staff because the Padres have not shown much margin when the bats go quiet. Xander Bogaerts leads San Diego with seven home runs, a .257 average, and 23 RBI, giving the Padres the top bat listed across the main offensive categories.
San Diego’s most recent game was a 7-1 loss at Milwaukee, and that result showed the downside of the current offensive form. The Padres scored only one run after beating Milwaukee 3-1 one day earlier. Walker Buehler gets the start with a 2-2 record, 5.20 ERA, 1.35 WHIP, 31 strikeouts, 12 walks, and three home runs allowed across 36.1 innings. San Diego’s staff owns a 4.14 ERA and 1.26 WHIP, with opponents batting .239. The Padres have enough pitching to stay close, but Buehler’s ERA gives Seattle a clear opening if the Mariners keep pressure on early.
