Yikes. I see where I goofed in specifying losses rather than wins, forgetting that the DB distinguishes between losses and absences. Past performance no guarantee of future trends, naturally, but given three out of four retirements, I hope we don't see the end of Takakeisho here and now, although it's hard to tell what more he can do to adapt his fighting style if he seems unwilling to risk injury.  Worth noting that Kirishima amongst the above four is an anomaly: he fought from the maegashira ranks only because he had difficulty in securing a kabu when his sponsor experienced the 1997 Asian Financial Crisis, so his choice to continue was sort of forced. On the other hand, there are a number of Nishonoseki kabu that are freeing up soon, so Takakeisho should have no issue waiting for them with his 3-year jun-toshiyori privilege if he does indeed decide to retire.
