Darvish has looked pretty good through 5 inning. A little bit shaky still with 7 hits and 3 walks, but he's also struck out 4 and only allowed one run [which was unearned].
Edit: Not a very good sixth, though. 2 hits, 1 run, 1 hit-by-pitch, 1 walk, and he only managed to get 2 outs before being relieved. Still, he had an improved performance overall, so that's definitely a good sign.
