Outgoing batting coach Thilan Samaraweera was disappointed at the manner in which Sri Lanka’s middle order folded, exposing tail-enders to Trent Boult’s high-quality swing bowling on day two at Hagley Oval. But as he prepares to leave his post to make way for new batting coach Jon Lewis, he also reflected on what he felt was a moderately successful 13 months in the role. Samaraweera is essentially being demoted to the High Performance staff, having been the national team’s batting coach since November last year. The decision to replace him came after Sri Lanka’s 0-3 Test series result against England last month. But despite the losses, Samaraweera says, there are numbers which suggest that under him the Sri Lanka top order has made significant gains.
