Kenley Jansen pitched a perfect bottom of the ninth inning against the Orioles for his 29th save on Thursday night, and it was the sort of uneventful outing that typically only gets a mention in the “Quick Hits” section of this column. Yet it was notable, not for what happened in this particular appearance, but how it fit into a larger trend.
The Dodgers’ closer threw 18 pitches, and only seven of them were in the strike zone.
