In the fourth, the Sens scored first when Chris McConnell reached base on a fielding error, scoring Gilbert, who led off the inning with a single and stole second base.
Norris, Erik Komatsu, Archie Gilbert, and Tim Pahuta had two hits each. It was also the third game in a row that Norris has homered in.
Sens starter, Danny Rosenbaum threw 6.2 innings, allowing six hits and one run, and improved to a 2-0 record with Harrisburg. Jimmy Barthmaier came on in relief of Rosenbaum in the seventh inning and pitched a solid 1 1/3 innings. He did not allow a hit and struck out two.
