SAN FRANCISCO — The Giants continued to tinker with the Buster Posey support group Monday, claiming catcher Tom Murphy off waivers from the Colorado Rockies in advance of their Bay Bridge Series game against the Athletics.
Murphy, 28, is the second catcher the Giants added in two days, coming after a trade for Erik Kratz from the Milwaukee Brewers in exchange for minor league infielder C.J. Hinojosa.
Aramis Garcia, who was Posey’s backup only a few days ago, was optioned to Triple-A Sacramento. There, Garcia joins Steven Vogt, the former A’s catcher who is recovering from shoulder surgery.
