Saville vs Kirchheimer prediction

Luke Saville vs Strong Kirchheimer in the 1st round of the Winnetka Challenger, USA, on hard court. I'm going to go with the underdog Kirchheimer here at 5.15 odds, I think the value is huge there. Kirchheimer a part time tennis player from USA ranked 962 in the world only played 3 matchs this season and lost them all but last season he showed some good form finishing the year 23-12 and with some wins against Sandgren (ranked 106) and Mott (ranked 212) Luke Saville is a pretty poor player tbh. He has been around the challenger ITF level for a while now and with no progression at all. He's 10-10 this year on hard but has not play on it since May. Saville played on grass (his best surface) but had a really poor season on it finishing 1-4. Saville is clealy getting worse and worse season after season. He's now 328 ranked player and without any confidence Kirchheimer had a slow start this season but only played ITF. Motivation in challenger is different, there's a huge opportunity for him here. The odds are really value good luck!
