Los Angeles Dodgers manager Dave Roberts likes to joke any issues surrounding his team are ''high class'' problems. A night after Rich Hill took a no-hitter into the 10th, Hyun-Jin Ryu worked six effective innings and the Dodgers pulled away late for a 5-2 victory on Thursday, their 90th win of the season. Ryu allowed one run and four hits with two walks and two strikeouts to improve to 3-0 with a 2.13 ERA since June 17.
