Rowand, a 34 year-old 11-year White Sox / Phillies / Giants veteran, has had significant struggles since 2010. Only appearing in 105 and 108 games for the Giants in 2010-2011, he averaged a triple slash of just .232 / .278 / .363, well below his career average .273 / .330 / .435. Rowand has earned 20 wins above replacement through his career over those 11 seasons, definitely nothing to sneeze at (consider the standard barrier to entry of the Hall of Fame is 20 years and 50 WAR, or thereabouts).
The Giants are still paying Rowand and owe him the last $12M of a 5 year, $60M deal.
