Key Matchups and Game Preview: Cubs vs Diamondbacks
The pitching matchup gives Arizona a noticeable edge. Chicago will start left-hander Matthew Boyd, who is 8-2 with a 4.15 ERA and 1.24 WHIP across 91 innings, allowing 85 hits while recording 71 strikeouts and 28 walks. Boyd has been solid against Arizona since joining the Cubs, posting a 1.64 ERA with 10 strikeouts across two starts, but his overall season numbers are still much less dominant than those of Eduardo Rodriguez. The Arizona left-hander enters 13-4 with a 2.61 ERA and 1.21 WHIP in 155 innings, allowing 138 hits with 110 strikeouts and 49 walks.
Chicago owns the stronger offensive profile, batting .250 with a .338 OBP and .424 slugging percentage while scoring 695 runs and hitting 177 home runs. Pete Crow-Armstrong has been the centerpiece of that attack, batting .276 with 33 homers and 83 RBI while carrying an impressive .550 slugging percentage. Arizona is batting .244 with a .317 OBP and .398 slugging percentage, with Nolan Arenado leading the team with 21 home runs and Gabriel Moreno batting .303 with a .382 OBP and .464 slugging percentage.
Rodriguez's consistency gives Arizona the better starting-pitching matchup, and the Diamondbacks have gone 39-29 at home this season. Chicago's deeper offense makes the run line less attractive, but Rodriguez should be capable of limiting the Cubs enough for Arizona to take the series finale.
