Tirso Ornelas

The Padres had a record-setting international signing class in the summer of 2016, and the early returns suggest Ornelas may go down as the best pure hitter from that class. He won't get much love on real-life lists, due to his corner-only defensive profile, but he could be a plus hitter with at least plus power. Ornelas finished fourth in the Arizona League in walk rate (16.8 percent) and ninth in OBP (.399) despite being the youngest hitter in the league (he turns 18 in March). His .133 ISO may not look like much, but evaluators project the 6-foot-4, 180-pound outfielder to grow into huge raw power as he matures physically. He could be held back in extended spring training before being sent to the Northwest League, but considering how impressive he was in his pro debut, the Padres could choose to aggressively assign him to the Midwest League. If he is sent to Low-A, don't expect much production, especially in the first half. This is a long-term investment that could pay off in a big way in 2021 or 2022.
