The Cincinnati Reds activated Graham Ashcraft from the Bereavement list on Saturday afternoon. In a corresponding roster move, the optioned relief pitcher Zach Maxwell to Triple-A Louisville. They also transferred the rehab assignment of Nick Lodolo from High-A Dayton to Triple-A Louisville. Ashcraft has mostly been Cincinnati's seventh-inning guy they can rely on when it's close late, especially when they have a lead. He's taken a big step this season. Through 15 games this season, the 28-year-old has an ERA of 1.20 and a WHIP of 1.267. Opponents are hitting just .202 off of him and slugging just .297 against him.

His ground ball% is 58.3%, which ranks in the 94th percentile of Major League Baseball.…
