But beating your BaseRuns record means (on the pitching/defense side) you are giving up base runners but not allowing them to score. Not sure why that would apply to the 2014 Royals to any great degree -- their top relievers allowed very few base runners, although their relief staff overall was average in WHIP, and their relievers as a whole had the lowest number of inherited runners in the league (and allowed them to score at a league average rate). And good defense should mean they allow fewer baserunners too, as well as stranding them. Not sure it would be the dominant factor for Perkins and the Twins this year either. Perk has been relatively stingy with base runners (1.083 WHIP), and only 5 inherited runners too. The team has 3rd most inherited runners in the AL, but they are stranding them at about a league average rate, average WHIP, and the 5th worst bullpen ERA in the league. I guess the Twins relievers (and starters too) have so few strikeouts, maybe that is a factor? Obviously runners are more likely to advance/score on outs that aren't strikeouts. Royals pitchers did not have huge strikeout totals last year either (although their bullpen was near the top, their starters were near the bottom).
