The Giants optioned Porter to Triple-A Sacramento on Monday, Alex Pavlovic of NBC Sports Bay Area reports. Porter served as a third catcher for a couple days and did not receive a plate appearance for the Giants.
The Giants selected Porter's contract from Triple-A Sacramento on Saturday, Ari Alexander of 7 News Boston reports. The Giants have an open spot on their roster for a catcher after trading away Patrick Bailey on Saturday, so Porter will get the call to return to the big leagues. The 30-year-old backstop has spent the entire season in the minors and owns just a .520 OPS through 42 plate appearances. He'll likely serve as a depth piece behind Jesus Rodriguez until Daniel Susac (elbow) returns from the injured list.
The Giants reassigned Porter to minor-league camp Monday, Justice delos Santos of The San Jose Mercury News reports. Porter spent the majority of last season with Triple-A Sacramento and inked a new minor-league deal that included an invitation to spring training following the season last October. He'll provide organizational catching depth for San Francisco.
