I had the same solution as Clement but my starting grid had r4c8=6 and the 6 removed from r6c9 and r9c7 because of the 58 pair in c4.

Whoops, of course that r9c7 was a typo (s.b. r9c8). I think I heard someone once say that it's possible to edit a post but I didn't see how. Can we fix typos in our posts Marty?

Another way round is the 568 XY-wing pivoted at r3c7, removing the 5 from r1c2.

How about two typos? R4 rather than c4.
