On Sunday, the Cardinals’ 2018 rookie class put on a stunning display. Jack Flaherty and Jordan Hicks each did something that had only been accomplished one other time in recorded MLB history. Tyler O’Neill’s performance didn’t quite reach such rarified air. All he did was go 3-for-4 and blast his second homerun in as many days, and then hit his third homerun in three games on Monday. These contributions come in tandem with a very solid beginning of the season from Harrison Bader, the pending return of Alex Reyes, and assorted contributions from Mike Mayers, Ryan Sherriff, and Francisco Peña (technically a rookie, although one who performed so well last weekend that the equipment manager playfully banished Yadier Molina’s locker to the supply closet).
