Meaning, the Yankee pitcher threw a seemingly innocuous 93 mph fastball--which happened to be ball four--straight through the glove of catcher Russell Martin. You don't see that kind of coal scorching, eyebrow waxing, stove melting sort of heat every day. This is some Backyard Baseball "Fireball" sh*t. 

The Yanks fell to the Blue Jays bay a score of 6-0, and the fireman gave up four runs in 4.2 innings pitched. Mixed messaging to say the least.
