BASEBALL DAILY REPORT : AROUND THE MAJORS : Thon Tells Athletics He’s Had Enough

Veteran infielder Dickie Thon retired after 14 years in the majors, saying continuing problems with his vision were forcing him to quit. Thon signed with Oakland last month, and his announcement caught the Athletics by surprise. Thon’s agent, Oscar Suarez, told the team Thon was having problems seeing batted balls on defense.

Thon experienced vision problems and severe headaches periodically over the past decade since being hit in the head by a pitch from Mike Torrez during spring training in 1984. . . . The Montreal Expos renewed the contract of Pedro Martinez, the pitcher obtained from the Dodgers for second baseman Delino DeShields in November. Martinez will be paid about $200,000 for 1994 after earning $119,000 last season.
