Fernando Tatis Jr.'s bright future was on full display once again on Wednesday as he connected on his first career grand slam as part of a two-homer performance to lead Class A Fort Wayne past Burlington, 8-1, in a rain-shortened game.
The Padres' No. 5 prospect (No. 100 overall) went deep in his first and last at-bats for the TinCaps, leading off the game with a solo shot before delivering a grand slam in the seventh to finish with a career-high five RBIs. The game was suspended due to rain after the following half-inning.
Making Tatis' pair of home runs all the more impressive was that he hit them both after working the count full, with the grand slam coming on the seventh pitch of his at-bat.
"I was really excited with how he worked that at-bat," Fort Wayne hitting coach Doug Banks told MiLB.com. "He didn't get too big in the situation and go chasing outside of the zone. That's kind of an organizational philosophy to be aggressive in the zone and Fernando did a great job in that at-bat."
The son of former big leaguer Fernando Tatis has hit 15 homers over his first 85 games as an 18-year-old in the Midwest League, all while slashing .279/.375/.511 with 20 stolen bases and 49 RBIs. The 6-foot-3 shortstop has been particularly hot lately, too, with a .455/.581/1.121 batting line, four home runs, six stolen bases and more walks (10) than strikeouts (eight) in 10 games this month.
"He came in with a lot of expectations, but to do what he's doing this year at just 18 years old, shows that he's on his way to being a five-tool player," Banks added. "It's fun to watch a kid with the type of makeup he has put it all together. He's a strong kid and shows up to play every day and is smart in the way he goes about his business, which is why he's up there in games played in the Midwest League."
Padres No. 8 prospect Jorge Ona also hit a solo shot in the first inning for Fort Wayne, his eighth of the season. He went 2-for-4 in the contest, while outfielder Buddy Reed (No. 27) went 3-for-3 with two doubles and two runs scored.
