The Giants re-signed free agent catcher Nick Hundley to a one-year contract, general manager Bobby Evans announced Tuesday. Hundley, who was the Giants’ Willie Mac Award winner in his first year with the club, hit .249 with nine home runs and 35 RBIs in 101 games as Buster Posey’s backup in 2017. Nearly half of Hundley’s hits — 32 of 70 — went for extra bases last season. “We are glad to welcome Nick back to the Giants,” said Evans. “We appreciated his contributions last year and we look forward to him wearing a Giants uniform again in 2018.”
