You can get to the HREF with XPATH & code, like this

    HtmlDocument doc = new HtmlDocument();
    doc.Load(myHtmlFilePath);
    // get to the A tag using XPATH
    HtmlNode a = doc.DocumentNode.SelectSingleNode("//td[@class='playerName']/a");
    // get the HREF attribute
    string href = a.GetAttributeValue("href", null);

but not beyond. You'll have to parse the href manually, here is a quick hack that works with your example:

    Uri uri = new Uri(@"dummy:" + href); // use whatever "drive-like" root
    Console.WriteLine(Path.GetFileNameWithoutExtension(uri.LocalPath));
