Sweet, maybe, but not lively although this has an unusual follow-through. Gary Rolfe joins a Capitals' farm team direct from high school, starts out at first base knowing his strength is in his performance at the plate. In high school and again here in the low, low minors the thought of catching behind the plate turns him off even if he can take over--reluctantly--in a pinch. Rather than face the prospect of moving up as a catcher and the uncertainties of making it, he returns home at the season's end and decides college would be a better base for a future. The ins and outs of starting professionals--living allowances and bonus babies, racial antagonisms in small towns, developing skills and eliminating weaknesses--come across with ease but the central situation and Gary himself could use pep pills. The Sweet Swing--a disappointing miss.
