BERLIN — The Berlin Little League Intermediate team rolled past Pennsylvania, 7-1, on Thursday morning in the semifinals of the eastern regional tournament behind a magnificent pitching performance by Tristan McDonough to advance to the threshold of a regional championship and a possible trip to California for the national tournament.

McDonough was outstanding on the mound for Berlin on Thursday, allowing no earned runs and no walks while scattering four hits and striking out a remarkable 15 batters. McDonough also helped his own cause at the plate, going 2-3 with a home run and two RBIs. Kevon Wharton was the star the plate for Berlin, going 2-3 with two home runs and three RBIs in the tidy, hour-and-a-half semifinal win. Wes Powell drove in Berlin’s other earned run, but most of the offense came via the home run thanks to the heroics of Wharton and McDonough.

As of late yesterday, Berlin was awaiting the outcome of the other semifinal between New Jersey and New York to determine who it would face in the regional championship, set for Friday at 11 a.m. Berlin beat both New Jersey, 7-4, and New York, 17-5, in pool play.
