I wouldn’t grab any Giants relievers. You can do better.
As far as not getting a closer, I don’t think it would have mattered much. There were simply too many holes to fill. Not only did they need a closer, they also needed another arm for the pen, another bat, and a number 2 starter. Too many holes to fill. Nen’s, Perez’s, and Ledee’s salaries all come off the books this season, leaving them about $14 million to spend. They will probably address those needs with that money.
