What happened: Jesus Luzardo has held opponents to a .504 OPS over that span, trailing only Dylan Cease in MLB. His 2.6 fWAR ranks third in the majors behind Tarik Skubal.
Why it matters: Luzardo's surge gives Philadelphia a top-end starter for September with an 81-63 record. The club sits four games behind Atlanta in the NL East and 4.5 games inside wild-card position.
By the numbers: Across the four cited categories, Luzardo owns three NL-leading marks and no MLB ranking worse than third.
What to watch: Luzardo's remaining starts will determine whether he can sustain those league-leading rates through the end of the regular season.
