Tsuyoshi Wada starting feeling discomfort in his left shoulder some time around February 7 or 9 (he canceled a bullpen session on February 7). He has not done much throwing since then and will be shut down for the rest of the third block of spring camp (the fourth block starts on February 15).
[UPDATE 2/16 @ 1:20am]
Wada resumed throwing with a light game of catch on February 15. He told reporters the shoulder was feeling better and that he felt good about how things were progressing.
