BASEBALL : DAILY REPORT

First baseman Keith Hernandez underwent successful back surgery, but is unlikely to play for the Cleveland Indians before the All-Star break. Ronald Moskovich, who performed the 90-minute surgery, predicted Hernandez would be able to walk later in the day, although he said the first baseman would probably need three months to fully recuperate. Hernandez, 37, signed a two-year, $3.5-million contract in December of 1989.
