Yu Darvish can mix in a clinker with gems. But he's worth this short price at home against the Braves, who are going with Byrce Elder, their No. 6 starter. 
Darvish had a 3.38 home ERA with a 0.95 WHIP last season. The prideful Darvish shut out the Diamondbacks in six innings during his first start. However, he was bashed by the Giants in his second start, not even making it to the second inning. I see him bouncing back here.
