As the baseball season grinds down, any major leaguer who isn’t a Yankee, Phillie, Dodger or Royal, and thus presumably headed for the playoffs, ought to be concentrating on batting and earned run averages. Next season’s contract negotiations are only a few weeks away. But Pittsburgh pitcher Rich Gossage demonstrated that the old competitive spirit never fades, even if your team is in second place. Indicating his displeasure with the night vision of umpire Bruce Froemming, Gossage was eventually sent to the showers, a trip he didn’t need since he wasn’t playing. The Pirates lost 10-2. Wait till next year, ump.
