"We're going to stay on top of this hamstring as best we can moving forward," San Diego manager Bud Black said. "He's doing well. He's encouraged."
Cabrera said Friday: "I feel really good right now. I feel like I can play the game. I'm probably like 80 percent."
Cabrera said he was 70 to 75 percent Thursday.
The 26-year-old is eligible to return to the Padres while the team is in Boston to face the Red Sox next week. However, Black said Cabrera would go through a rehab assignment before rejoining San Diego's lineup.
Cabrera said he had been working on running the bases and getting his confidence back while monitoring his progress.
