"All I want is one RBI per game for the rest of the season—that would give me over 150 for the year. As far as homers go, I'd like to better my alltime high of 39. And I can't see anything wrong with finishing with my average over .300, can you?" said Orioles First Baseman Boog Powell last week. No hitter would find anything wrong with the totals Powell suggested. They all add up to a dream season, and each of the goals is within his reach. So might be the MVP trophy. With 49 games to play, the 28-year-old, left-handed slugger had a .302 average with 31 home runs and 103 RBIs and was enjoying the most extraordinary season of a nine-year yo-yo career. In 1966, for example, Powell averaged .287 with 34 homers and 109 runs driven in, but the next season his figures read, .234, 13 and 55. Now the bulgy 6'4" 240-pounder hopes he has matured to permanent stardom, and all because of an injury. Powell began slowly this season, but in May was kneed in the chest by an opponent. His sore rib cage forced him to shorten his stride at the plate, and he has been a booming batter ever since. Adding seven RBIs last week, he took over the league lead in runs driven in. If he meets his one-a-game goal, Powell will be the first American Leaguer since Ted Williams and Vern Stephens in 1949 to knock in over 150 runs. He will have ample help doing it with Paul Blair (.306) and Frank Robinson (.327) batting ahead of him in the Baltimore lineup. The only danger may be that his teammates will help him too much. The Orioles have been winning games at a record pace—they could become the first team in the majors since 1954 to have a .700 winning percentage for the season—and they should clinch their division title early. If they do, Manager Earl Weaver admits it will mean more cautious play by Baltimore, rest for the star players and, perhaps, fewer RBIs for Boog Powell.
