Pick Ideas

Cardinals moneyline with perceived pitching and record edge

St. Louis’ slight advantage in overall record and McGreevy’s stronger performance profile support a play on the Cardinals moneyline.

Cardinals -1.5 run line for plus-price upside

McGreevy’s ability to limit big innings and Arizona’s vulnerability when Kelly struggles make the Cardinals -1.5 a viable high-upside angle.

First five innings wager favoring St. Louis

A first-five wager isolates McGreevy’s efficiency against Kelly’s more volatile 2026 performance, reducing late-game bullpen variance.

Merrill Kelly walks allowed prop over

Kelly’s 2.1 average walks per game in 2026 suggests value on the over for his walks allowed, particularly if he continues to labor through deep counts.

Michael McGreevy strikeouts prop over

Coming off a six-strikeout performance, an over on McGreevy's strikeouts is appealing if sportsbooks set a modest threshold.
