Noah Syndergaard stands seven inches taller than Bartolo Colon and 45 pounds slimmer, if the Mets’ official register is to be believed. He did not earn his nickname, Thor, by mere chance. And so the notion of Syndergaard thwacking balls over fences does not seem as far-fetched as that of Colon doing anything close to what he accomplished with his first career home run Saturday in San Diego.
