On a day when the Giants cut three players, a pair of familiar faces returned to the clubhouse at Scottsdale Stadium. Santiago Casilla was here early this afternoon and Angel Pagan just walked in, completing the WBC cycle for the reigning champs (hitting coach Hensley Meulens is back, too). Casilla had two shiny medals in his locker, but that’s not what caught the eyes of reporters. Resting near his shoes was a banana, a gift from Marco Scutaro, who was playfully mocking that whole plantain thing. Casilla said the WBC experience was fantastic, and he would do it again — but he also said that it was different than winning a World Series title. Not good different or bad different, just different. “The emotion is unbelievable when you play for your country,” he said. “Everybody was watching us in the Dominican.” Afterward, everyone was partying. Asked how long the celebration lasted, Casilla flashed a wide smile. “Oh!” he said. “Nobody was sleeping.” Casilla was flooded with text messages right after the game and received plenty of hugs from teammates Thursday afternoon. He talked excitedly about the Dominican Republic’s bullpen (“everybody throws hard — 97, 98″) and joked that he grooved a pitch to Pagan when the center fielder lined a triple (“I said, ‘Hey, only fastballs for you.’ “) Most importantly for the Giants, Casilla said his arm feels great. “I’m ready to go,” he said.
