I got this off of Baseball America, that the Giants have signed two international free agents.

OF Angel Joseph - 16 yo switch hitter from the Dominican republic signed for 6 figures. He reportedly got larger offers from other clubs but wanted to sign with the Giants. Andy Baggarly compares him to Alfonso Soriano (though im sure its a stretch) BA says he's a leadoff centerfield type player but Baggarly says the Giants expect him to fill out, gain more power and stick as a corner outfielder.

LHP Maladi Perez - 20 yo he supposedly was going to get a huge signing bonus from some other clubs before it came out that he was 20 years old instead of the previously believed age of 16. However he is 6'5" and left handed so its worth taking a little risk I think.

Here are the links, the second one is the Giants organizational report from BA so unless you subscribe you won't be able to see it, though I pretty much paraphrased what it says anyway. the second link only talks about Angel Joseph and doesn't mention Perez.
