Will Smith is more than just a lefty specialist; he has no career platoon split, possesses a three-pitch mix and has struck out more than 30 percent of batters he faced in each of the last three full seasons. He's coming off a knee injury and wasn't throwing at full strength earlier this season but has been reaching 92-94 mph more often over the last few weeks. The Giants have a great history with relievers, especially with guys like Smith who are more than just specialists, and he provides a substantial boost to a bullpen that has been a real weakness for the team this year.
