White Sox LHP prospect Hagen Smith threw 4 2/3 shutout innings for Triple-A Charlotte on Sunday, striking out nine and allowing three hits.

Smith also walked three, so he was unable to complete five innings yet again, but he did throw 92 pitches in this outing, which is the most he’s ever thrown in pro ball. In his last three starts, Smith has allowed three runs on nine hits in 14 innings while striking out 25 and walking six. He has only completed five innings in one of those starts, so efficiency and command remain key issues for the 22-year-old, but he seems to be starting to round into form.
