The Rochester Red Wings fell to the Worcester Red Sox, 6-1, in a rain-shortened five-inning game on Monday night at Frontier Field.
The game was tied after three innings, but Worcester put up a five-spot in the top of the fourth inning to take the lead right before the rain started falling.
Jack Dunn drove in the only run with a sacrifice fly in the bottom of the second.
Washington Nationals left-hander MacKenzie Gore made another rehab start for Rochester and surrendered all six runs on six hits over 3 2/3 innings.
The two teams will meet again on Tuesday in the second game of this three-game series. The first pitch is scheduled for 6:05 p.m.
