Son's club organization has an MLB scout who coaches higher level team and circulates across the older teams. Something he has told guys during games more than a few times is basically "I've never had another scout or recruiter ask me 'can so and so work counts, bunt, and take walks'... They only ask me 'who can rake'." Of course game situation and spot in the order might dictate different approach at times, but for guys trying to get noticed... Nobody gets recruited for useful OBP, they want hitters. Just like they don't recruit crafty effective RHPs, they want power arms.
SG, I am very sure that is true. The question gets raised then as to how do HS aged players learn to "play" the game, including hit/run, hitting behind runners, advancing runners and the like..
To provide some information for contrast, when our son was in Milb one of the major graded elements for every hitter was pitches seen per AB. I think the requirement was something around 5 pitches per AB was the minimum expectation. This was posted daily.
A different Milb team actually resorted to requiring every hitter in their line up to take one strike for a period of time(3-4 weeks during a 144 game schedule.)
While proving you can rake is part of the equation, it seems different colleges and MLB organizations could want more from a hitter. As an illustration, proving you can rake might need refinement and not work completely at Fullerton, Oregon, Vanderbilt, Texas, and UCLA, for instance, if you cannot play their type of offense with the 4 guy bunting, advancing runners, putting pressure on the defense, etc. From a different college view point, Stanford still seems to rely on the ability to rake approach. When they run into pitching of the type they saw at Vanderbilt last weekend, they end up with results where they outhit Vanderbilt 7-4 but lose the game 4-2 and the ability to rake puts up 4 runs in 3 games.
Some of this might also be geographic, at least in college. Other than Vanderbilt, many West Coast teams play a very different type of offensive college baseball than the ACC and SEC.
Again, as many have said in this thread, there is no substitute for the ability to hit in HS. On the other hand, I wonder about and welcome your thoughts about whether and how that "ability" might be defined or visualized based on the level of play and whether it is different during a HS season in a team environment vs a Summer season and a travel or showcase situation?
