In the afore-mentioned top of the 10th, J.P. Crawford (2-5, 2 R) led off with a single, advanced to second on the play on an error charged to Norfolk CF L.J. Hoes and later scored on Knapp's single to give the Pigs the 5-4 lead.

RHP Frank Herrmann (1.0 IP, BB) earned the win for the IronPigs to improve to 4-1 on the season. RHP Edward Mujica (1.0 IP, 2 K) tossed a scoreless 10th to notch his league-leading 16th save of the year.

LHP Zach Phillips (1.0 IP, H, 1 R, 0 ER, BB, K) was dealt the loss for the Tides and drops to 5-3 on the year.

In the top of the second, solo shots from Darin Ruf (3-5, 2B, HR, 2 RBI, R) and Darnell Sweeney off of Tides starter T.J. McFarland opened up a 2-0 lead for the IronPigs. The home run was Ruf's eighth of the year and Sweeney's fourth.

McFarland (n/d) gave up the four runs on eight hits while walking one and fanning one over five plus innings of work.
