I am assuming those are runners thrown out at the various bases.
I may be wrong -- I took only a quick glance -- but Boston's numbers do not look much different than the numbers of other AL teams.
(Of course, this does not take into account whether sending the runner or taking the extra base was the right thing to do or a crazy bone-headed mistake. It's simply the raw numbers.)
