The San Francisco Giants are hiring University of Tennessee coach Tony Vitello as their manager for his first professional coaching job. It’s a bold gamble by San Francisco executive Buster Posey on a coach with no previous experience in the pros. The 47-year-old Vitello is making the jump after spending his entire career at the college level. He guided the Vols to their first NCAA title last year. The Giants went 81-81 this season under Bob Melvin. Posey calls Vitello “one of the brightest, most innovative and most respected coaches in college baseball today.”
