This apparently actually happened

From last night's A's/Orioles game, I saw this in the boxscore:

HR: Davis (3, 8th inning off Bierd, 3 on, 2 out).

Do you know who "Davis" is? The one, the only, Rajai Davis. He entered last night's game as a pinch-runner for Jack Cust in the eighth inning of a 3-2 game, then later in the inning hit a grand slam to make a 7-2 game an 11-2 blowout. That gave him this awesome line for the night:

Davis, PR-DH 1 2 1 4 0 0 0 .247

That's 1/1 with two runs scored, four RBIs, no walks and no strikeouts. That's just not something you see every day.
