Starter Miles Mikolas pitched seven shutout innings as the Cardinals split their four-game series vs. the Cincinnati Reds.
Steven Matz has no wins and a 5.72 ERA this season. He’s allowed a National League-worst 68 hits. This is not some new and unfortunate phenomenon.
Nearing the end of a 19-game, 19-day test, Oliver Marmol rested the middle of his order Thursday. An internal 'fatigue tracker' informs that decision.
Mikolas and former Cardinals' first-rounder Luke Weaver went zero for zero through eight innings, and the Cardinals rested three of their All-Stars.
