Baseball Prospectus on Bryce Harper's strikeout versus Julio Teheran:
"Teheran started Harper off with a fastball away for a called strike. The pitch was probably a couple of inches outside, but Teheran hit his spot, so he got the call. Teheran then missed low on a change, but he wasn’t afraid to double up with the offering, this time throwing his change at the knees. Harper was way out in front. Up 1-2, Teheran went to the same spot as his first pitch, stretching the zone on the outside corner, and again got the call. From what I can tell, getting Bryce Harper off-balance isn’t overly challenging, but it is imperative, because when Harper times a pitch, he hits it hard. Teheran threw one pitch in the zone for a swinging strike and earned called strikes on two pitches out of the zone. He was in total command of that matchup."
