Giants reinstate Anthony DeSclafani, designate Tyler Chatwood for assignment

The Giants announced several roster moves Sunday, reinstating right-hander Anthony DeSclafani from the injured list and first baseman Brandon Belt from the paternity list. To make room for those two, infielder Thairo Estrada was optioned to Triple-A and right-hander Tyler Chatwood was designated for assignment.

It’s a quick turnaround for DeSclafani, who went on the IL on August 19. That’s great news for the Giants, as the righty has been tremendous for them this season. Over 132 2/3 innings, he has an ERA of 3.26, producing 2.1 fWAR already on the year. With Johnny Cueto also having recently returned from the IL, the Giants rotation is in great shape for the stretch run, as they try to hold off the Dodgers in the NL West. The Giants are currently atop the pennant race by 2.5 games.

It’s potentially the end of a very short tenure in San Francisco for Chatwood. He was designated for assignment by the Blue Jays in July after struggling with command issues. In 28 innings out of Toronto’s bullpen, he had an ERA of 5.46, thanks in large part to a bloated walk rate of 16%. (League average for all pitchers is 8.7%.) The Giants then signed him to a minors deal April 7 and added him to the big league roster 10 days later. In two games for the Giants, Chatwood racked up four innings with six strikeouts but also allowed five runs (three earned) with one walk and one hit-by-pitch. The 31-year-old will now go on waivers and, if unclaimed, will be able to elect free agency. If he joins a new organization before the end of the month, even if it’s a minors deal, he will be eligible to play in the postseason for that club.
