Some background from MLB.com’s Astros game report:

The woman, identified only as Sarah, was struck on the right arm by a foul ball off the bat of Chris Johnson in the fourth inning while sitting down the left-field line — a ball that she didn’t see coming because her boyfriend ducked out of the way at the last second.

“As soon as we got here and I saw where we were sitting, I said ‘Baby, we’re going to get hit,’” the woman said when interviewed during the game. “He said, ‘No, I’ll catch it if you do. We just had this conversation and sure enough, the ball comes at me. He just bailed.”
