The Rockies might have the bullpen arm the Giants are searching for, and he should come at a mostly reasonable price.
I’m a Josh Osich fan. That is, I’m pretty sure he’s going to be an excellent reliever for a long time, and he just needs a little polish. That written, I’m not sure about him facing Adrian Gonzalez with the bases loaded in Game 5 of the NLDS. Also, you know the Giants are facing the Dodgers in the first round of the postseason, right? Good, good. Start drinking now.
Point being, it’s entirely reasonable to expect the Giants to get a new left-handed setup option.
