Orrick, Herrington & Sutcliffe announced Tuesday that Silicon Valley–based corporate partner Mitchell Zuklie will succeed Ralph Baxter, Jr. as chair of the 1,100-attorney firm.

The 43-year-old Zuklie is by far the youngest of the four Orrick partners vying to take over the firm’s top management post when Baxter closes out his two-decade-plus run at the top at the end of 2013. The other contenders were Los Angeles–based finance partner Alan Benjamin, San Francisco–based litigator Walter Brown, and New York–based litigator James Stengel.
