Should Met Fans be worried about Johan Santana?

After coming off elbow surgery which required the removal of loose bone ships in the elbow, Johan Santana looks far from stellar. Santana who was limited to 25 starts last season, took the mound for the second time in 2010 on Sunday and looked awful. In the first he was all over the place giving up 2 walks & 4 runs due to a Josh Willingham grand slam. Some say that Johan Santana looked as if his elbow was bothering him as he was clenching his teeth and looked very uncomfortable. After the game, Santana said his fastball wasan't on and it was cutting and he was unable to command it.
Now to me, we all know Santana is a competitor so it makes me think if he might be hurting and not telling anyone about his issue. On the other hand, he has only had two starts, and his first start was very Johan Santana like. If you ask me, i am not worried yet, if he gets knocked around next start i will be scared out of my mind, but for right now let's go fight in Colorado & hope to take the brooms out.
