San Francisco Giants pitcher Tristan Beck undergoes vascular surgery for an aneurysm. Beck will be sidelined for eight weeks. The team is already thin on pitchers with starters Alex Cobb and Robbie Ray recovering from surgeries. Options include looking at potential free agents like lefty Jordan Montgomery and All-Star Michael Lorenzen.

The Giants rotation will have to rely on young prospects like Kai-Wei Teng and Trevor McDonald, who have limited experience. Depth could be an issue, leading to potential roster moves before Opening Day to bolster their pitching staff.
