Vladimir Guerrero Jr. has been touted as one of baseball's rising stars all season long — but with his performance in last night's Home Run Derby, Vlad Jr. made himself known in a big way. The 20-year-old came out swinging, hitting 29 balls over the Progressive Field fence in Cleveland in the first round to break the previous record of 28. The Toronto Blue Jay matched his record in the second round, slamming 29 dingers — a number that was matched by Joc Pederson of the Los Angeles Dodgers.
