What happened

The Orioles were the latest victims of yet another automated ball-strike system snafu on Wednesday.

Why it matters

With two outs in the bottom of the second inning of their 8-5 loss to the Diamondbacks, Baltimore third baseman Coby Mayo took a 3-0 pitch from Arizona starter Eduardo Rodriguez near the outside corner that home plate umpire John Tumpane called a strike.

Common ground

As Tumpane made the call, Mayo started his walk toward first, thinking the pitch from Rodriguez was off the outside of the plate.

Perspective signals

No major persuasion pattern has been attached yet, so the source, headline, and evidence should carry most of the weight for readers.
