Arizona took Monday's opener 5-4 and enters at 42-42, while San Francisco is 35-49 and 19.5 games back in the division. Landen Roupp starts for the Giants with a 5-7 record, 4.07 ERA, 1.29 WHIP, 95 strikeouts, 34 walks, and five home runs allowed over 86.1 innings, while Brandon Pfaadt counters for Arizona at 0-1 with a 5.92 ERA, 1.50 WHIP, 31 strikeouts, 17 walks, and seven homers allowed across 38 innings.
