Dave McNally, a 20-game winner for the fourth season in a row, survived a rocky start to win the opener. He trailed, 3–0, after four innings pitched, giving up three doubles and a triple. The A's had McNally tottering in the second inning. With two runs home, a runner on second and none out, second basemanDick Green came to bat. It was at this point that A's manager Dick Williams made the first of several ultra-cautious moves which were to fuel criticism of his playoff strategy. He ordered Green to sacrifice, which put runner Dave Duncan on third with one out. The next batter was Blue, whose bunting ability is well known, Vida tried to squeeze the run home, But the O's had guessed correctly on what was coming. McNally pitched out and Duncan was nailed in a rundown. Blue proceeded to strike out, and the A's splurge was over. McNally gave up another run in the fourth, but that ended the A's scoring forays. Meanwhile, 24-game winner Blue yielded just one run and three hits during the first six innings. However, disaster overtook Vida in the very next frame. Frank Robinson led off with a walk and Boog Powellstruck out. Brooks Robinson's single sent Frank Robinson to second, after which Andy Etchebarren's fly to right advanced Frank Robinson to third. Now there were runners on first and third with two down, and Blue appeared likely to quell the flurry without damage. After all, he'd beaten the O's twice in two tries during the season. And the next hitter was shortstop Mark Belanger, hardly a nemesis to any pitcher. But Belanger rifled a single to center to score Frank Robinson and ignite thunderous cheering from the crowd of 42,621. Then Curt Motton, pinch-hitter hero of a '69 Oriole playoff victory over Minnesota, stepped up to bat for McNally. Curt slammed a double to the left-field corner, plating Brooks Robinson and tying the score. Center fielderPaul Blair followed with the blow that doomed Blue, a two-run double to left. Reliever Eddie Watt blanked the A's the last two innings and Oakland was one game down. Skipper Williams was subjected to further sharpshooting for his failure to remove Blue, or even visit the mound, during the seventh-inning barrage. Dave Johnson's error in the sixth inning was the only miscue between both teams in the series.
Game 2
Catfish Hunter held Baltimore to seven hits, but unfortunately for him, four of them were home runs. Boog Powell walloped two, Brooks Robinson and Elrod Hendricks the others. Cuellar displayed his usual pitching artistry, a baffling assortment of curves and change-ups which the A's solve for a mere six hits. Typical of the A's super-cautious approach to their task was an incident in the sixth inning when they were trailing, 2–1. Reggie Jackson led off against Cuellar with a double. Cleanup hitterTommy Davis was up next and to the surprise of everyone in the park, he bunted. The next two hitters were easy outs. Davis' sacrifice, it turned out, was not ordered by Williams.
Game 3
Jim Palmer's performance in the deciding game was not among his most noteworthy—he permitted three home runs, two of them by the slugging Jackson and the other by Sal Bando. But all three shots were struck with the bases empty, and Palmer had more than enough to pitch Baltimore's pennant clincher for the third straight year. Loser of his only two starts against Baltimore during the season, Diego Segui reached the fifth inning of Game 3 with the score 1–1. Then he met his "Waterloo". The crusher was Brooks Robinson's two-run single. It came after Williams ordered an intentional pass to Hendricks. loading the bases. Bando's homer cut the A's deficit to 3–2 in the sixth. But in the seventh, Frank Robinson's double and Darold Knowles' wild pitch put Baltimore out of danger. The Orioles collected 12 hits off Segui and his four successors, with Don Buford's triple and two singles leading the way.
