That stint with the Yankees ruined him. He was strikeout prone prior to that but he had a borderline nervous breakdown. It can happen. See Steve Sax, Chuck Knoblauch (!!!), Carl Pavano to name a few. Some guys just can't handle New York.
Based on his stat line, Irvin throws a lot of junk. Guessing he'll keep his breaking stuff out of the zone and hope the Twins chase. Been the Achilles heel for a while now. Have some plate discipline and force him to throw strikes. Do that and they could tee off.
Exact same record last year at this time. It's not so much the Twins failing to meet expectations as it is Cleveland and Kansas City being so much better.
