TODAY: Moscoso has elected free agency, per the MLB transactions page, indicating that he cleared waivers and declined to accept an outright assignment in the San Francisco system.
NOVEMBER 20: The Giants announced that they have designated pitcher Guillermo Moscoso for assignment. In related news, San Francisco added center fielder Gary Brown, right-hander Kendry Flores, third baseman Adam Duvall and right-hander Hunter Strickland to the 40-man roster.
The Giants acquired Moscoso from the Cubs in exchange for cash or a player to be named back in July. Moscoso had a 3.93 ERA with 9.0 K/9 and 4.5 BB/9 with Triple-A Iowa but didn't fare quite as well in his short time on the Giants' varsity squad. Moscoso turned in a 5.10 ERA with 9.3 K/9 and 6.3 BB/9 in 30 innings of work.
