"Overall, it was good," Affeldt said. "I could have been a little more aggressive. But sometimes in those situations it's tough to feel the same aggression that you do [in a game]."
Affeldt certainly underwent an aggressive throwing program, however. He limbered up his arm with long toss, warmed up in the bullpen and pitched in the game before playing more long toss. "I put as much pressure as I possibly could on it, and it was fine," he said.
Assistant athletic trainer Anthony Reyes and strength and conditioning coach Carl Kochan were present to supervise Affeldt. Neither general manager Brian Sabean nor any of his top assistants appeared to be on hand, perhaps reflecting the organization's confidence in Affeldt's health.
In the game, Affeldt faced seven batters and allowed two singles, neither of which was hit particularly hard. He coaxed four groundouts and recorded a strikeout.
