Fernando Tatis Jr. is showing no signs of slowing down.

The 18-year-old shortstop’s breakthrough season is continuing in the Dominican Republic’s winter league with a blistering start that has seen Tatis – the Padres’ top prospect – fashion a circuit-best 1.283 OPS through five games. The effort includes a home run, two doubles, four walks and just two strikeouts in a 6-for-15 showing from Tatis, who was drafted No. 1 overall by Estrellas Orientales after zooming from low Single-A Fort Wayne to Double-A San Antonio in his first full year in the Padres organization.

ESPN scouting guru Keith Law is among those who’ve pegged Tatis as a top-10 prospect in all of minor league baseball after he combined for 22 homers, 32 steals and a .278/.379/.498 batting line in 131 games across two levels in 2017.

The expectations, so far, haven’t fazed Tatis.


“That pushes me to work even harder,” he said last month at Petco Park at the Padres On Deck Game, “because people are expect a lot from me so I have to bring it even more.”
