Meyer, a LHP from Downey, California, was the Phillies 1st Round pick (#14 overall) in the June 1967 draft. He is often cited as one of the Phils' many draft busts (the Phillies do not draft well) but this isn't as bad as taking Jeff Jackson over Frank Thomas or anything like that…Jon Matlack, John Mayberry and Ted Simmons were already off the board by the time the Phillies picked, and the only player of value taken in the next dozen picks was Bobby Grich by the Orioles at #19.
(Of course, after *that*, three of the next four picks [#27-30 overall] were Vida Blue, Dave Kingman and Jerry Reuss, but clearly they were considered lesser prospects, as everyone [except the Cardinals who went Simmons-Reuss in rounds 1-2] had already passed on them.)
I don't know if Meyer had chronic injuries or if he had military commitments, but he hardly pitched his first four professional seasons, tallying only 45 games from 1967-1970 and no more than 73 IP in any season, despite working almost exclusively as a starter. He was on the Phillies' 1969 spring roster, but I don't have any pictures of him in camp, just this one once he was sent down to Spartanburg (A-ball, Western Carolinas League):
In 1971, the Phils finally got a decent amount of work out of Meyer, as he started 21 times for AAA Eugene in the PCL. But he still only threw 85 innings, as he was bombed early and often. (3-10, 6.67 ERA; it was his first work above A-ball.) Perhaps hoping the experience had toughened him up, the Phils invited him to Spring Training, 1972:



Despite the fact that the '72 Phils definitely needed pitching (Steve Carlton, 27-10; rest of team, 32-87), Meyer was sent down to AA Reading, and he stunk up the joint, going 1-3, 7.12 in 13 games (4 starts) and was (I think) released. He signed on with Burlington in the Carolina League (Rangers affiliate) and was 3-2, 2.68 in 11 games (also 4 starts) for them, but that was the end of the line for Meyer.
