Fernando Tatís Jr. says he fell ill with the COVID-19 virus several days ago, which meant he had to watch the party from his couch when the San Diego Padres clinched a playoff spot Monday. He returned to the Padres’ lineup on Friday after missing three games, and Tatís made sure the baseball world knows he’s healthy and ready for October. Tatís blasted a grand slam in the fourth inning of the Padres’ 7-4 victory over the Arizona Diamondbacks on Friday night, swinging the momentum in a win that kept San Diego in contention for a home playoff series.
