Arizona’s core bats aim to pressure rookie under the Arch

Arizona's core bats, Corbin Carroll and Ketel Marte, provide speed and power to test McGreevy early.

Pick Ideas

Diamondbacks moneyline if McGreevy’s small sample is overvalued

Pfaadt's superior experience and McGreevy's limited track record support backing Arizona if St. Louis is overvalued on home-field buzz.

First five innings under leaning on recent starter efficiency

Pfaadt has allowed just five earned runs over his last four outings and McGreevy yielded one earned run in two of three July starts, supporting an early under.

Pfaadt strikeout over only at modest numbers

With a modest 6.7 K/9 rate, Pfaadt's strikeout prop is best targeted at conservative thresholds rather than inflated lines.

Cardinals team total under based on recent look at Pfaadt

St. Louis managed just two runs off Pfaadt across 5.1 innings last time, making a team total under appealing if set aggressively.

Live-betting angle favoring Cardinals if McGreevy settles in

McGreevy's durability into the sixth inning with low damage makes live-backing St. Louis viable if he escapes early pressure.
