Key Matchups and Game Preview: Phillies vs Mariners
The Phillies will turn to left-hander Jesus Luzardo, who has put together an excellent season with an 11-5 record, 3.35 ERA and 1.15 WHIP across 156 innings. Luzardo has allowed 133 hits while recording an impressive 194 strikeouts against only 47 walks, giving Philadelphia a significant swing-and-miss weapon as it tries to avoid being swept. Seattle counters with right-hander Bryan Woo, who is 9-8 with a 4.10 ERA but an excellent 1.08 WHIP through 138.1 innings. Woo has surrendered 121 hits, struck out 137 and walked only 29, showing outstanding control even though his ERA is higher than Luzardo's.
Philadelphia owns the better offensive numbers overall, batting .242 with a .313 OBP and .402 slugging percentage while scoring 602 runs and hitting 159 home runs. Kyle Schwarber remains the Phillies' biggest power threat with 39 home runs and 78 RBI, while Brandon Marsh leads the club with a .274 batting average and carries a .433 slugging percentage. Seattle has produced a .230 average, .310 OBP and .377 slugging percentage while scoring 526 runs, although Randy Arozarena has provided a steady middle-of-the-order presence with a .272 average, 20 home runs, 58 RBI, a .369 OBP and .461 slugging percentage.
Luzardo owns the stronger overall pitching profile and Philadelphia has the more productive offense, creating a good opportunity for the Phillies to prevent a sweep. However, Woo's 1.08 WHIP and excellent control should keep Seattle competitive.
