"We'd like to see [Silva] throw well and get him back," interim manager Mike Quade said. "The more options the better [as] we're approaching September."
Silva, who is 10-5 with a 3.92 ERA in 20 starts, has been on the 15-day disabled list since Aug. 2 for a cardiac evaluation. He underwent a cardiac ablation, an outpatient procedure to correct an irregular heartbeat, on Aug. 9.
"He says he feels great after that [procedure]," Quade said. "You know, technology's amazing. Rebuilding a guy's arm and rebuilding a guy's heart. Unbelievable."
