Padres vs Diamondbacks Key Matchups and Game Preview
San Diego's Frontline Starter
Michael King takes the mound for San Diego after posting a 6-7 record with a 3.38 ERA and 1.17 WHIP across 125.1 innings. The right-hander has struck out 109 hitters while allowing just 97 hits and 13 home runs, giving the Padres a dependable frontline starter capable of working deep into games.
Arizona's Contact-Management Approach
Arizona counters with Brandon Pfaadt, who is 5-1 with a 4.00 ERA and 1.29 WHIP over 72 innings. Pfaadt has surrendered only eight home runs and 21 walks while limiting opponents to 72 hits, although his lower strikeout total of 49 suggests he relies more heavily on inducing weak contact than overpowering hitters.
