The TinCaps and South Bend are tied 4-4 after six innings.
Fort Wayne had some clutch hitting from second baseman Maxx Tissenbaum in the fourth to take an early lead.
With runners on second and third and two outs, Tissenbaum sent a single into left field that scored two runs and made it 2-1.
But TinCaps starter Bryan Rodriguez gave up four hits and three runs -- two earned -- in the fifth inning. He finished with three earned runs, eight hits, seven strikeouts and two walks to his credit.
Ruben Mejia came on for Rodriguez in the sixth and retired his first three batters. He has two strikeouts after his first inning.
And in the bottom of the frame, the TinCaps whittled into the lead a bit more.
The TinCaps got a one-out double from left fielder Luis Domoromo, who is 3 for 3 so far. He advanced to third on an error by third baseman Cesar Carrasco, and came in thanks to a single from first baseman Luis Tejada.
Two batters later, third baseman Diego Goris scored on a throwing error by shortstop Andrew Velazquez to tie the game.
