When Los Angeles Manager Walt Alston made a last-minute decision to start Bob Bailey instead of Ken Boyer at third base Tuesday, he walked over and personally told Cardinals' Manager Red Schoendienst about the change. Schoendienst has been wishing ever since that Alston had not bothered to make the trip. Bailey, a former Pirate $175,000 bonus player from Long Beach, Calif., promptly went on a hitting streak that drove St. Louis out of the league lead. In his Tuesday start, he collected three hits including a homer and drove in five runs as the Dodgers defeated the Cards 9-2. Two nights later his single with two out in the 11th inning gave Los Angeles another win and dropped St. Louis to second place. And in Houston the next night Bailey clouted a 450' three-run home run in the 10th to win the game. In all, the 6', 175-pound infielder batted .417 for the week, with 10 RBIs. A streak like that would be a morale booster for anyone, but for Bailey, who hit just .227 in 1967, it was a lifesaver. "Until now I have been terribly disappointed with myself and I'm sure the Dodgers have been, too," he said. Alston had his own viewpoint. "Bailey's story is simple," he said. "Last year he was too cautious and wasn't swinging at pitches on the corners. Bob's a strong hitter and when he swings he's valuable, but when he takes a pitch over the plate he doesn't help us at all." Proving his manager's point, Bailey made both of his game-winning hits on first pitches, and in one Dodger loss, when he singled twice and figured in both of his team's runs, Bailey knocked out his hits on the first and second pitch. "I'm being more aggressive now—I'm attacking the ball again," he said. And how.
