Shoddy fielding by Peoria helped the TinCaps to an early lead on Friday night and they went on to earn a 9-4 victory, their second straight over the Chiefs.
The TinCaps (6-8) clinched their first series win of the season, thanks in part to six errors by the Chiefs. Peoria (8-6) committed four of those errors in the TinCaps' three-run second inning.
The TinCaps finished with a season-high 16 hits.
Genison Reyes recorded four outs in relief to earn the victory.
TinCaps starter Coby Cowgill pitched four shutout innings. The righty gave up two hits and walked one while throwing 50 pitches, 32 for strikes.
The finale of this three-game set is 5 p.m. Saturday. The TinCaps were expected to start Yimmi Brasoban, but he threw 48 pitches Friday. Peoria is set to pitch lefty Chase Brookshire.
