Indianapolis (66-53) claimed the lead in the first on Jordan Luplow's seventh Triple-A blast and 23rd of the season. The Tribe never looked back thanks to their left-handed ace.
Brault faced five Syracuse (45-75) batters in an inning one time all night after he issued back-to-back walks to Neftali Soto and Brandon Snyder to open the fourth. He escaped further damage by retiring the next two batters on consecutive pitches and striking out Michael Almanzar on a 1-2 heater.
Indy extended its lead to five with a four-run sixth, sending nine batters to the plate against the combination of John Simms and Kevin Jepsen. Max Moroff walked and Luplow singled ahead of a Danny Ortiz RBI single that made it 2-0. Elias Diaz then cranked a 3-0 pitch from Simms to the wall in left-center for a two-run double to chase the Chiefs' right-hander. Later in the inning, Gift Ngoepe drilled a run-scoring single to center.
Syracuse scored single runs in the eighth and ninth against Montana DuRapau and Brett McKinney, but the Tribe scored three in the home half of the eighth to run away as victors. Erich Weiss roped a pinch-hit two-run double to highlight the inning.
Brault (10-5) yielded two hits and three walks with five punchouts to improve to 10-2 with a 1.43 ERA in 16 games (15 starts) since May 6. In 11 home games (10 starts), the 25-year-old is now 5-3 with a 0.84 ERA. He has allowed a total of six earned runs in 64.0 innings pitched at Victory Field this season.
Simms (0-3) remained winless in four Triple-A starts after surrendering five runs on seven hits over five innings of work.
The Indians and Chiefs cap their four-game series Sunday afternoon at Victory Field. The Tribe will send righty Clay Holmes (8-5, 3.44) to the mound while the Chiefs will counter with righty Erick Fedde (1-1, 5.57). First pitch is set for 1:35 p.m.
