Giants prospect third baseman Adam Duvall went 1-for-3 with a home run and a walk for Triple-A Fresno on Saturday, raising his season line to .299/.368/.647. Duvall is leading the Triple-A Pacific Coast League in home runs with 19, but is stuck in Fresno with the suddenly-hot Pablo Sandoval entrenched at third base and Mike Morse taking the bulk of the playing time at first base. The 25-year old Duvall has progressed slowly through the Giants organization since being drafted in the 11th round in 2010 out of Louisville.
