As baseball’s offseason begins, Giants will begin to address their issues

The Giants considered a formal announcement Thursday to name Astros assistant Alonzo Powell their new hitting coach, but decided to wait until next week to allow the San Francisco native to enjoy Friday’s World Series parade in Houston.

Having raided the two World Series organiztions for coaches — Powell from the Astros and bullpen coach Matt Herges from the Dodgers — the Giants will continue to focus on hiring a pitching coach.

Meanwhile, the Giants’ most important player-acquisition period in two decades began Thursday morning when 149 players were declared free agents.
