Sergio Romo (Mexico), Ryan Vogelsong (USA), Jeremy Affeldt (USA), Javier Lopez (Puerto Rico), Santiago Casilla (Dominican Republic), Marco Scutaro (Venezuela), Pablo Sandoval (Venezuela), Jose Mijares (Venezuela), and Angel Pagan (Puerto Rico) will all be playing in the WBC and will miss much of Spring Training with the squad in Arizona.
What this could now do is provide a golden opportunity for some of the other camp invitees to step in and shine.
With Guillermo Mota and Clay Hensley out of the picture, there were already two spots in the bullpen up for grabs. When you pair that with Romo, Lopez, Mijares, and Affeldt all in the WBC, there will be plenty of opportunity for guys to step into some unfamiliar roles.
Two guys to specifically look at will be Dan Runzler and Heath Hembree.
Runzler has spent parts of four seasons with the Giants and was hampered last season with a shoulder injury. The 27-year-old left-hander has had control problems and has 44 batters in 72.1 Major League innings.
Hembree got a bunch of attention last season and was seen as the future closer of the team. An elbow strain slowed his progress as well.
The hard throwing right-hander threw 38 innings for Triple-A Fresno and had a 4.74 ERA.
Dan Otero, who madethe Major League roster out of camp last season, might also be able to seize a spot. Jean Machi or Eric Surkamp will also likely be in the mix.
The Giants will be without nearly their entire bullpen in Spring Training and it do nothing but heighten the competition for spots on the Opening Day roster.
