Omar Vizquel wants to play another year of baseball, and it really doesn't seem to matter where. According to his Twitter page, if he was offered a contract with the San Francisco Giants, he would say, "Let's go now."
Admittedly, what this link does not say is that the Giants are indeed interested. However, I think that they could be interested in Vizquel.
I previously wrote that the Phillies could be interested in Vizquel as a mentor for young shortstop Freddy Galvis, so it is definitely possible that the Giants could be interested in the same type of treatment. They have young shortstop Brandon Crawford who they have already committed to starting at shortstop.
Vizquel definitely knows how to play shortstop as he has played 2,908 games at the position over 23 seasons. Because of that, I could almost see this type of move happening with Vizquel as a backup and mentor.
The question I would have about whether or not the Giants are interested in Vizquel is that signing veterans hasn't worked out so well for them lately. They ended up cutting Aaron Rowand and Miguel Tejada and Pat Burrell is probably retiring. Every decision should be viewed independently of all the others because Vizquel is a different player, but maybe this is somewhere in the minds of the Giants' management.
Whatever happens, I hope that Vizquel signs somewhere. He still wants to play, and he still is a serviceable option at shortstop. More importantly though, he could be a great influence on any young shortstop.
