The big-budget San Diego Padres, desperate to turn around their disappointing season, obtained 43-year-old left-hander Rich Hill and first baseman/ designated hitter Ji Man Choi from the Pittsburgh Pirates on Tuesday for three players. The Padres are led by stars Fernando Tatis Jr., Manny Machado, Juan Soto and Xander Bogaerts, yet are buried in fourth place in the NL West, 8 1/2 games behind the Los Angeles Dodgers, and five games out of the third wild-card spot, with four teams ahead of them.
