QUEENS — The Giants are, objectively, a worse team now than they were at the beginning of the week. Camilo Doval is a Yankee . Tyler Rogers is a Met . Mike Yastrzemski is a Royal. Taking their places on the active roster are right-handers José Buttó and Kai-Wei Teng, who will start on Saturday, as well as outfielder Grant McCray. Additionally, infielder Christian Koss returned from his rehab assignment and fellow infielder Brett Wisely was optioned to Triple-A Sacramento. If the Giants didn’t lose 13 of their last 15 games before the deadline and drop below .500 for the first time all season, president of baseball operations Buster Posey would’ve been in the business of buying. Instead, he sold.
