Trout is not in the starting lineup for Sunday's game against the Mariners, Rhett Bollinger of MLB.com reports.
Jose Soriano has picked up 16+ whiffs in each of his last two starts and even with some inefficient starts on his tab, he's been able to hit this over with regularity, missing just twice since the start of April. He's running a swinging strike rate above 13% since the start of May and he'll face a lineup that largely has not faced him much prior to this start. With a deep arsenal of pitches, I'm taking the over on 5.5 Ks and 0.5u on the 7th strikeout.
