From a SL perspective, I think what's missing from our ODI attack is some middle overs penetration, while we can do the strangle pretty well, it's harder in 50 overs than 20, so we need to supplement Sachi with a spinner who can take wickets during the middle overs and keep pressure on through wickets rather than simply run rate, because run rate can be made up but wickets can't. I think that's where Herath comes into the equation and Mendis doesn't, today Mendis did well early because the batsmen refused to go hard at him, which played into his hands, but when the game was taken to him he struggled, although after benefiting from a poor shot he kept Jordan quiet by using his variations well, I'll give him that. It's clear that SL have good opening and death bowlers, although the death bowling has been suspect this tour, but some more penetration in the middle overs would top it off, and we need Herath there because we don't have a pace option that can do that job for us.
