In the bottom of the fourth, a single and a walk put two men on with two outs before Sweeney plated both runners with a two-run double to give the Pigs a 3-0 lead.
PawSox starter Henry Owens (9-7) allowed the four runs on five hits while walking three and fanning six in 5.2 IP.
A three-run sixth tied things at three apiece for Pawtucket as Chris Marrero knocked home a pair with a two-run double, went to third on an error and scored on Jantzen Witte's sac fly to tie the game.
Pigs starter David Buchanan (9-9) gave up three runs (two earned) on seven hits to go along with two walks and two strikeouts in 7.0 IP. LHP Joely Rodriguez (1.0 IP, H, K) and RHP Luis Garcia (1.0 IP, 2 K) got the final six outs for the IronPigs. Garcia notched his 13th save of the year and extended his scoreless streak to 16.1 IP.
