The 1971 American League Championship Series was a matchup between the East Division Champion Baltimore Orioles and the West Division Champion Oakland Athletics. The Orioles swept the A's in three games, despite the fact that each team had won 101 games. The Orioles won their third consecutive pennant in the process, but lost the 1971 World Series to the Pittsburgh Pirates. This was the first of ten ALCS series between 1971 and 1981 that featured either the Oakland Athletics or the Kansas City Royals. The only time neither team appeared in the ALCS during that period was in 1979. Summary Oakland Athletics vs. Baltimore Orioles Game summaries Game 1 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 baseman Dick 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 Powell struck 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.
