Teacher: Now, understand the problem? Solve this instance: Passage: The Royals drew first blood in a back-and-forth opener that featured high offensive output from both teams. After hitting just three home runs in the regular season, Alcides Escobar hit a one-out homer to left to give the Royals a 1–0 lead. Later in the inning, with the bases loaded, Alex Gordon hit a broken bat, looping fly ball that dropped just fair inside the right-field line to plate all three runners. Suddenly, it was 4–0 Kansas City. Baltimore got a run back in the bottom of the inning on Adam Jones' RBI-single, but it could have been more had it not been for a great diving catch by Gordon in the left-center field gap, robbing Steven Pearce of a hit. In the bottom of the fifth, after the Royals added a run in the top of the frame, the Orioles finally got to James Shields. Nelson Cruz added to his postseason legacy with an RBI-double and Ryan Flaherty delivered a two-run single to make it a one-run game, 5–4. In the sixth, after a walk to Jonathan Schoop and a flare single to right by Nick Markakis, Alejandro De Aza hit a high chopper past the pitcher's mound that shortstop Escobar had no play on; Schoop scored to tie the game. Jones hit what appeared to be a double play ball, but Mike Moustaskas' relay throw short-hopped first baseman Eric Hosmer and the inning continued to bring up Cruz. He could not deliver the big hit this time as he rolled into an inning-ending double play.
