Giants activated INF Marcelo Mayer from the 10-day injured list.

Mayer will make his San Francisco debut during Monday’s series opener against the Twins at Oracle Park. The 23-year-old former top prospect, who came over from the Red Sox in the Erik Miller swap at the trade deadline last month, has been out nursing forearm and foot injuries since late June. He’s talented enough to be an impactful fantasy contributor at some point in the future, but it simply hasn’t happened at this early juncture of his career. He could benefit exponentially from the change of scenery, but is unlikely to offer much in the final week of the regular season.
