There was a common theme in the four wild-card series games that kicked off Major League Baseball's postseason on Tuesday. Three of the four winning sides received dominant pitching from their southpaw starters and the fourth benefitted from a very serviceable effort as well.

Detroit's Tarik Skubal got the ball rolling by striking out 14 and holding the Guardians to a single run in 7 2/3 innings. Chicago's Matt Boyd left his start in the fifth inning down 1-0 but the Cubs rallied for a victory. Garrett Crochet matched Skubal's line with three fewer strikeouts during a 117-pitch masterpiece. Dodgers ace Blake Snell put a capper on the night by taking care of the Reds with seven innings of two-run ball.

All told, lefty starters threw 28 2/3 innings while surrendering five earned runs and racking up 36 punchouts. In the cases of Skubal and Crochet, the electricity of their performances were through the roof and a reminder that both have a reasonable case to claim the title of best arm in baseball.

The quartet of performances led MLB Network analyst Chris Young to offer up a take that might be hard to completely fact-check yet seems legit.

"Today was the best day ever that I've seen with left-handed starting pitching," he said.

Young then asked purists to go back through the record books and prove him wrong.

On its surface what he's saying holds some water. Especially if extra weight is given to the magnitude of the games being played. It helps a lot that the baseball playoffs have expanded to the point where there are four games per day in the earlier rounds yet doesn't diminish the accomplishments.
