Stevenson actually had an opportunity to add to his impressive line when he batted in the top of the 13th inning, though Hartford opted to intentionally walk the Senators' leadoff hitter. He would come around to score on a double later in the frame, providing Harrisburg with an important insurance run.

Ryan McMahon also had a memorable game for the losing Yard Goats. The Rockies' No. 8 prospect set career highs with five hits and six RBIs, ultimately finishing a double shy of hitting for the cycle. He knotted the score at 12 apiece with his third home run of the season, a game-tying, three-run shot with two outs in the bottom of the ninth, and tallied singles both in the 12th and 13th innings to finish 5-for-7.
McMahon, 22, is batting a robust .413 through 11 games to begin the season, and he now paces all Eastern League hitters with 14 RBIs.
Together the two teams combined to score 30 runs on 30 hits in a game that required five hours, 35 minutes to complete.
