Luis Arráez following in Tony Gwynn's footsteps with Padres - ESPN

Comparisons to Tony Gwynn began to follow Luis Arráez when he first established himself in the big leagues, growing more prevalent as the hits piled up and the batting titles followed. Arráez wasn't as prolific, but his skills and the way he utilized them — consistently spraying baseballs to unoccupied spaces all over the field, barreling pitches regardless of how or where they were thrown — made links to one of history's most gifted hitters seem inevitable.

Tony Gwynn Jr., the late Hall of Famer's son, often heard them and largely understood them. But it wasn't until the night of May 4, while watching Arráez compile four hits in his debut with the same San Diego Padres team his father starred for, that he actually felt them.

«I honestly had goosebumps watching him put together at-bats,» said Gwynn Jr., a retired major league outfielder who serves as an analyst for the Padres' radio broadcasts. «It took me back to watching film with my dad as he was basically doing the same thing.»

Gwynn was universally celebrated throughout the 1980s and '90s, but Arráez stands as a polarizing figure in the slug-obsessed, launch-angle-consumed era in which he plays. Some, like the Miami Marlins team that traded him away earlier this month, see a one-dimensional player who doesn't provide enough speed, power or defensive acumen to build around. Others, like the Padres, who used four prospects to acquire him at a time when trades rarely happen, see the type of offensive mastery that more than makes up for it.

What's inarguable is that Arráez is the ultimate outlier.
