Yeah, with the Horton injury and how he developed last year, then essentially ran out of innings at the end of the year, it wouldn't surprise me if we see him going like 2 innings at a crack for a month or two. Then, ramp him up in June, assuming he's a viable big league option at that point, so you have him as a rotation possibility for the playoffs and you're not worried about how many innings he's thrown this season.
It's certainly possible it's an injury but that would be some odd phrasing if that's the case.
