Cincinnati trailed 4-2 before Castellanos connected for his sixth career grand slam, 運転する 1-1 fastball from Neftali Feliz (0-1) deep to center for his 15th homer. Castellanos thrust his fist in the air as he circled the bases.
It was Feliz’s first big league appearance since 2017. He came on after Bailey Falter pitched four innings of one-run ball in relief of Spencer Howard.
Cincinnati’s seventh-inning rally was sparked by Alejo Lopez, who was called up earlier in the day from Triple-A Louisville. He pinch-hit with one out and singled on the first pitch.
The Reds added six more in the eighth, blowing it open against the Phillies’ sputtering bullpen. Eugenio Suárez and Tyler Stephenson scored on a throwing error by reliever Enyel De Los Santos. Castellanos drove in Jonathan India with a two-out double, and Joey Votto added a solo drive.
Alec Bohm and Ronald Torreyes each drove in two runs for the Phillies.
Heath Hembree (2-3) pitched a scoreless inning for the win.
