There is no nightmare in baseball, no feeling of competitive vulnerability, quite like seeing your pitcher getting peppered by a lineup that knows exactly what pitch is coming.

It is a nightmare Andy Pettitte lived in Game 6 of the 2001 World Series, when the Arizona Diamondbacks trucked him for six runs in two-plus innings of a 15-2 victory, a pounding they later acknowledged came with the benefit of tipped pitches.

It is a nightmare Tampa Bay Rays starter Tyler Glasnow lived earlier this month, when he yielded hits to five of the first six Houston Astros in a winner-take-all Game 5 of the American League Division Series and later said it was “pretty obvious” he was tipping his pitches based on the position he held his glove.

And it’s a nightmare Stephen Strasburg endured for two grim starts against Arizona that sullied an otherwise impeccable 2019 resume, before he and pitching coach Paul Menhart discovered and, so they believe, swept up the bread crumbs the Diamondbacks followed to hit him hard.
