Four players ranked by Baseball America among the top 30 San Diego Padres prospects — including Fernando Tatis Jr., whose father played 11 years in the big leagues — are assigned to the Fort Wayne TinCaps for the start of the 2017 season.

Tatis is entering his second year as a pro, after batting .273 with 4 HR, 25 RBI and 15 SB in 55 games split between two levels lower than the Midwest League. Although Baseball America ranks him No. 17 among Padres prospects, MLB Pipeline has him much higher at No. 8.

Fort Wayne is the first stop for outfielder Jorge Ona (No. 12), a native of Cuba who left the island nation for the Dominican Republic before signing with the Padres last July. (He did not play professionally last year.) Baseball America says he has the potential to hit 25 homers annually, with above-average bat speed and plus-power to all fields. He could be the “stop-and-watch” player during at-bats at Parkview Field this season.

Infielder Hudson Potts (No. 14) is entering his second season as a pro, after batting .280 with 1 HR, 27 RBI and 10 SB in 59 games split between two levels lower than the Midwest League. According to Baseball America, Potts’ “average speed and potential to be an above-average defender at third give him a chance to be a well-rounded everyday player.”

LHP Logan Allen (No. 19) returns to Fort Wayne after posting a 3.33 ERA with 47 strikeouts and 22 walks in 54 innings/15 games/11 starts for the TinCaps last year. Still only 19 years old, Allen is projected by Baseball America as a reliable back-of-the-rotation starter with solid-average command, deep pitch mix and good tempo on the mound.
