Context: “I sick, I have nervous stomach. I can hardly eat. I’m taking lot of vitamins and I’m getting stronger. But I still sick.” [... ] Clemente said he’s been bothered by stomach trouble since last August. "During the winter I feel real bad. I lost 18 pounds but I’ve picked my weight back up a little since then. I don’t feel too strong and sometimes when I run I get short of breath. Sometime I feel good and sometime I don’t feel like playing ball at all.” [... ] “If I get a little stronger, I hit with more power and I help the club more.”
