Never heard of him. Was he a drinker and wencher and steroid user like so many of them? Or was he a straight arrow? If he was one of the out-of-control ones, maybe the baseball league can be sued for enabling a wild guy like that to have enough money to fly, who knows?
Lidle was a journeyman starting pitcher -- unspectacular at most times, but could give a team a solid run of 150 or so innnings in a given year. Played for at least a half a dozen teams starting with the A's and moving around from there, mostly in the American League. Seems like he's been around forever.
PS - From memory, I think the Indians boat accident was only Tim Crews and Steve Olin killed, Bob Ojeda surviving.
The excellent Deadball Era website, http://www.thedeadballera.com/ has details on many accidental, intentional and natural passings of major leaguers.
