The problem with high school catchers

The 2013 draft class is considered a little below average, but one area in which it has depth relative to recent years is prep catchers.

There are three high school backstops who rank among Keith Law's top 25 draft prospects, and when Reese McGuire, Nick Ciuffo and Jon Denney are selected in Thursday's MLB amateur draft -- likely in the first round, according to Law -- teams are hoping to get a future star. Each possesses the necessary tools to one day be an impact player at the major league level, and with time that could happen.

But history says otherwise.

"High school catchers don’t make the big leagues," a National League West scout said this week.

Of the 63 starting or backup catchers, roughly 20 percent were drafted out of the prep ranks at that position. You can count on your hands the amount that eventually made it out of the minors in the past decade.

What’s the reason for this lack of success? Should teams be wary about taking a high school catcher in the first or second round? I spoke to some evaluators to find out.
