The Senators' kid keystone combo, eight years later: Lenny Randle, bad news; Toby Harrah, good news.

The N.Y. Mets, who rescued Randle from would-be oblivion after the Texas Rangers suspended him for punching then manager Frank Lucchesi two springs ago, dropped the little fellow yesterday. Randle turned out to be a gentlemanly, civic minded New Yorker and third baseman, rewarding the Mets with a fine .304 bat in '77. But he slumped to .233 last year, was trailing Joel Youngblood in the battle for positiion this spring-and now, with the Met acquisition of Richie Hebner from Philly, Randle has his walking papers.

And, check this: Randle has three years remaining on a five-year contract reportedly worth $500,000, but word is he will not be paid because the contract was not guaranteed. The rescue had its limitations.
