PEORIA, Ariz. -- Fernando Tatis Jr. is the youngest player in any big league camp this spring. But he's already proving he belongs.
Ranked by MLB Pipeline as the game's No. 8 overall prospect, Tatis mashed an opposite-field home run in his second at-bat of Spring Training. He fell behind in the count against Mariners right-hander Shawn Armstrong, before swatting a 1-2 fastball over the Padres' bullpen in right field.
Tatis, who turned 19 in January, set a franchise record with 21 homers for Class A Fort Wayne.
