GAME: Blue Jays (53-60, 5th, AL East, -15.0 GB) at Mariners (52-61, 3rd, AL West, -12.5 GB) GAME #: 114. SERIES: 3rd of 3 games. MEETING: 6th (Twins lead 3-2). WHEN: Wednesday, 7:10 p.m., Safeco Field. STREAKS: Mariners L 2; Blue Jays W 3. TV: Root Sports. RADIO: ESPN 710, Mariners Radio Network

On May 7, the Tampa Bay Rays put up a second-inning four-spot against Toronto starter J.A. Happ when Desmond Jennings rocketed a line drive toward the box. This is how The Associated Press described the play: “The line drive that hit A.J. Happ in the head hit him so hard the ‘thwack’ could be heard up in the press box. The ball went all the way into the bullpen in foul territory halfway down the right-field line. Happ dropped face down at the front of the mound.”

“It was devastating,” said Happ’s teammate, R.A. Dickey. “I could barely watch it. You just don’t know what to think. It paralyzes you a little bit. And when it sounds like two bats, when you hear the sound off the bat and it sounds like it hits another bat, it’s scary, really scary. I just started praying on the spot.”

Last September, Oakland right-hander Brandon McCarthy was hit in the head by a line drive that fractured his skull and caused an epidural hemorrhage and brain contusion. He underwent surgery for six hours and didn’t pitch the rest of the season. In June, McCarthy suffered a seizure related to his head injury and missed two months.

Wednesday afternoon, in the third of three between the Blue Jays and Mariners, Happ will make his first major league start since May 7 when the Jennings line drive fractured his skull, and the ensuing fall caused a sprain of his right knee. If any Seattle opponent is worthy of a round of applause, it is Happ.
