Did the giants seriously undervalue Jesus Guzman?

I will say that all the injuries that occurred to this giants team, this year, may skew one's view of what has transpired with this teams offense.   People were hoping to get a healthy Sandoval back, with a full season of Posey, and a repeat of a 2010 Huff, along with the sparkplugs of Freddie Sanchez, and Andres Torres at the top of the lineup.  We also had Mr. Clutch Ross is Boss for a full season, and Brandon Belt waiting in the wings to be the next Posey, and then some.   For 2 years we had Jesus Guzman in Fresno, a player whom the the giants always said could hit, but were worried that his fielding made him better suited to be a DH.   The Padres picked up Guzman.  They had a prospect first baseman in Rizzo, after trading away A-Gon.  But Rizzo's struggles has made Brandon Belt look like Ted Williams. In the interim, Guzman has been called up and so far, has been the second most productive hitter in the NL since the allstar break.  Sabes decided to keep the left handed hitting Huff who had a nice year in 2010 by awarding him with a two year 22 million dollar contract.  All the while he had Belt, and Guzman ready to go.  Lets look at the stats of the most productive hitter in the NL post allstar break,  Troy Tulo,  the second most productive hitter,  Jesus Guzman,  and  Aubrey Huff.  Huff has not been that bad since the allstar break but his stats compare unfavorably to Guzman.

                                               AB     R     H    2B    3B    HR   RBI    SB    CS    BB   SO    AVG   OBP     SLG   OPS

Tulo                                      100    15   41   13     0      5      23        2       1      13    21     410    470      690    1160

Guzman                                 78    16   30     8     0      4      25        4        0       6     13     385    429      641    1070

Huff                                         78     7    24     3     0      3        7         2        1       8     10     308    364      462      826

Of course the sample size is small, but Tulo has been known to have good second halfs.  Also if one takes into effect that many of Tulo's games are played in Denver, while half of Guzman's games are played in San Diego, possibly a worse hitters park than SF,  Guzman's numbers are impressive.   Tulo is a premium fielder, and obviously neither Huff nor Guzman are.   Just how bad is Guzman in the field?   Let us see how the rest of the year plays out.    Since he has  been inserted in the lineup, the run production for the Pads has gone up.   Huff seems to be keeping the status quo offense with the giants as they are scoring less runs per game than Tiger does the deed each day, and that is after rehab.   

The poll should have the word knew instead of new.   The poll should have the term paper bag, instead of paper box.
