For some players the season just past was an up year, for some it was a down year and for others a combination of both. Mike McCormick of the Giants had an up year. In 1960, McCormick won 15 games for the Giants. Then came arm trouble, a trade to the Orioles, a trip to the minors and, last year, a mild comeback with the Senators, who dealt him to the Giants in the fall. Back with his old team, McCormick won 22 games. Boog Powell of the Orioles was down. In 1966 he hit .287, had 34 homers and 109 RBIs. This season he batted .234, hit 13 homers and had 55 RBIs. Mike Epstein went to the Senators in the most bizarre trade of the year and reached his zenith early with a grand slam in his first at bat against his former Oriole teammates. Alas, Epstein wound up hitting .215. Jack Lamabe's case was the reverse. His first pitch as a Met in Shea Stadium was hit for a homer, but then he was traded to the Cardinals and helped them win the pennant. For Jim Bunning of the Phillies the season was not so much up or down as it was a roller-coaster ride between the two. On April 21 at Shea, where, in three years, he had won eight times in a row (five by shutouts, once on a perfect game) he lost to the Mets. What's more, when Bunning fell off the mound as the result of his peculiar motion (right), he was hit on the rump by a line drive. His biggest upbeat moment came on Memorial Day at Candlestick Park when his high pop fly was picked up by a friendly gale and wafted over the fence for a game-winning homer. Bunning won 17 games and might have had 20 had he not lost five 1-0 games. On the up side, Bunning could at least take comfort from Walter Johnson, who lost 27 1-0 games during his career.
