MILWAUKEE — After almost two years of working his way back from surgery, Taylor Williams can finally focus on just doing his job for the Milwaukee Brewers. And, what a job he’s doing. Williams, the former Camas High School standout, has become a key member of the bullpen that has helped the Brewers to 55 victories at the All-Star break, tied with the Central Division rival Chicago Cubs for most in the National League. “I think this is probably the first year where he knew his role,” said Brewers pitching coach Derek Johnson, known for developing young pitchers over 11 seasons in the same role at Vanderbilt University.
