You mean up on Downs. It's like the effects of alcohol, a depressant, which slows body/brain controls and filters, causing the user to initially appear "rowdy"... until, the drinker crashes, mentally and physically (hopefully not operating machinery).
Smart baseball men sell high. But I just don't understand why the Red Sox, with an obvious need for a full-time starter at second base -- maybe even this year, in a possible pennant race -- aren't playing their Number Two organizational prospect (one ahead of Duran on SoxProspects.com) there now in Triple A.
