Layne has a 3.86 ERA, two strikeouts and a hold through four appearances so far this season.
The Yankees have only played seven games thus far, so it appears they plan on calling Layne's number frequently. He's only pitched 2.1 innings in those four appearances though, and each time he came in with a left-handed hitter due up first. While he's capable of getting out righties as well, it seems as though he'll mostly be deployed as a lefty specialist, thereby limiting much of his fantasy value to his ability to rack up holds.
