Seattle Mariners left-hander Danny Hultzen, the No. 2 overall pick in the 2011 MLB draft, tore through Double-A this year in his first full season in pro baseball (1.13 ERA in 13 starts), but has been less effective since a late-June promotion to Triple-A, going into Saturday night's start at Tucson with a 4.33 ERA and 21 walks allowed in 27 innings.

On Saturday, he showed flashes of what I'd consider his "normal" self, attacking hitters aggressively in the strike zone, but problems staying online to the plate in the first and his last two innings led to all seven runs he allowed.
