Watch: Dodgers pitching prospect Yadier Alvarez, 20, touches 100 mph in Single-A game.

GLENDALE, Ariz. — In his longest outing of spring training so far, Dodgers pitching prospect Yadier Alvarez was clocked at 100 mph on the radar gun in his third and final inning of a Single-A game against the Kansas City Royals at Camelback Ranch.

Two of the three scouts I spoke with had the 20-year-old clocked at 100; the other had him topping out at 99.

The Dodgers are expected to assign Alvarez to Single-A Rancho Cucamonga or Great Lakes to begin the season. Alvarez, who is from Cuba, signed with the Dodgers for a $16 million bonus last July.
