It's way too early for Iggy to come up, unless they think he can cover the range that Aviles can't while playing with Youk. I think WMB will get optioned down to Pawtucket, against everyones wishes.
He's not struggling as much as he's just coming back down to earth after his torrid start. I think he's keeping the seat warm for Iggy, and then he'll be back in the role he was last year.
What are you going to school for? I'm going for Sport Management major now, in the Mark H. McCormack Department of Sport Management, in the Isenberg School of Management
