The on-field accomplishments of Reggie Jackson, the Yankees' high-priced acquisition, from high school standout to current superstar, told in a running patter sure to satisfy young admirers. Sullivan makes it clear that Jackson, a power hitter with speed and strength, was no bargain at the outset--too many errors and strikeouts and a hot temper to boot. But determination and an off-season spent in Puerto Rico with boyhood hero Frank Robinson honed his skills and mellowed his outlook. Sullivan plays fair with Jackson's arrogance--the clenched fist at Finley, the tangles with teammate North--and touches all professional bases (records, awards) even if he skims over the man outside the park. Considering Jackson's promising start this year, a likely popular choice.
