Toronto Blue Jays manager Cito Gaston was admitted to a Toronto hospital yesterday with an inflamed sciatic nerve and a herniated disk.

The club did not say when Gaston, 47, would be released from the hospital but indicated he probably would need at least a week of bed rest.
* Umpire Joe West, upset that a replay of a routine play at the plate was shown on a video screen last night, threatened to forfeit the second game of the Cardinals-Mets doubleheader at Shea Stadium unless the scoreboard was shut off immediately.

* National League umpire Bruce Froemming charged that Gene Orza, general counsel of baseball's players union, took "cheap shots" at umpires.

Froemming said, "What he knows you could put in a thimble."
