Luis Guillorme, one of the Mets’ top defensive prospects, coolly barehanded a bat that flew out of the hands of Marlins hitter Adeiny Hechavarria and toward the New York dugout. While his teammates ducked for cover, the 22-year-old infielder tracked the lumber into his non-catching hand without any hesitation, and then flipped the bat back to Hechavarria all in one fluid motion.
