Duffy emerged as one of the top rookies during his 2015 campaign, finishing second in the NL ROY voting. Duffy gave the Giants, as well as their fans, a lot of hope after losing Pablo Sandoval to the Red Sox. Duffy durned out to be a lot better option than Sandoval, putting up tremendously better numbers and contributions than the Panda.
