Senators 4, RubberDucks 3

Story lines: Two RBI from major-league rehabber Bryce Harper (left hand) helped stake the Senators to a three-run lead in the ninth inning at Canal Park. The RubberDucks’ only run to that point came in the third inning, when Jake Lowery tripled and scored on Jordan Smith’s double. But Harrisburg reliever Tyler Herron struggled to slam the door shut, giving up a leadoff homer to Anthony Gallas and issuing back-to-back walks to Bryan LaHair and Tony Wolters with no outs. With the potential tying run at the plate, the Senators went to Robert Benincasa. The right-hander retired the first batter he faced before Ronny Rodriguez doubled to pull the Ducks within a run. Benincasa then retired the side.

Quick hits: Center fielder Tyler Naquin, who leads the Ducks in hits with 93, left the game in the bottom of the eighth inning after being struck by a pitch on his right hand. Naquin marks the Ducks’ third starter out of the lineup. Shortstop Francisco Lindor (nose) and second baseman Joey Wendle (wrist) are already sidelined.

Next game: 7:05 tonight at Canal Park. RubberDucks right-hander Duke von Schamann (3-1, 3.27) and Senators right-hander Colin Bates (0-0, 3.86) are scheduled to pitch.
