David Pastore of Stamford, Conn., will take a two-shot lead into Wednesday’s third and final round of the 113th Massachusetts Open Championship.

Pastore fired rounds of 68 and 66 to reach 10-under at TPC Boston in Norton. In second place was amateur John Broderick. Broderick, playing out of Dedham Country & Polo Club, has been consistent, carding rounds of 68 and 68.

One shot back of Broderick in a four-way tie for third place at 7-under were Kyle Gallo of Berlin, Conn. (70-67), Brad Adamonis of Ponte Vedra, Fla. (68-69), Mike Van Sickle of Wexford, Pa. (71-66) and Nicholas Pandelena of Atkinson, N.H. (68-69).

The inaugural event was won in 1905 when the legendary Donald Ross was the winner at Vesper Country Club in Tyngsboro.
