Los Angeles Times' high school reporter Eric Sondheimer tweeted breaking news Tuesday evening that Harvard-Westlake High (Studio City, Calif.) righthander Lucas Giolito hit 100 mph in a start against El Camino Real High (Woodland Hills, Calif.). A quick text to head coach Matt LaCour confirmed the report and he assured Baseball America that the guns weren't hot.

"My gun is slow and he hit 97 in the sixth," he said. "The first pitch he threw in warm-ups, you could tell it was different."

Giolito went 6 1/3 innings against El Camino Real, allowing one hit and no walks while striking out eight.

The top high school prospect for the 2012 draft, there is early speculation that Giolito could be the first high school righthander to be selected first overall. He has everything you can ask for in a prep arm. He stands at 6-foot-6, 230 pounds with broad shoulders and strong legs. He sat in the low to mid 90s last summer, but took a step forward this fall and has been easily reaching the high 90s. He has a low-80s curveball with sharp, downward break and a good changeup with a sink. He has an easy delivery and can lull hitters to sleep with his slow tempo before he explodes toward the plate.

Nobody is keeping an official record of high school players that have hit triple digits with their fastball, and since Pitch FX hasn't come close to reaching down to the high school level, there really isn't any way to have an official reading on anyone. Righthander Colt Griffin—the ninth overall pick of the 2001 draft out of Marshall (Texas) High—is considered to be the first high schooler documented to reach the century mark, something Baseball America reported at the time (subscriber only link). Oklahoma high school righthanders Dylan Bundy and Archie Bradley reportedly hit 100 last spring, but official confirmation is hard to come by.
