The Travelers took both ends of a Tuesday doubleheader at Harley Park, 4-3 and 11-1, against United Missouri Bank -- Boonville's Senior-level Babe Ruth League club.
Marshall never trailed in the opener, getting on the board in the second inning when Henry Tietz walked, went to third on a bunt and Caleb Willis' single, and racing home on a wild pitch.
Tyler Cott singled and Zach Bishop walked with one out in the third, both coming in on Tietz' sacrifice fly to right field.
Boonville caught up with a three-run third, which began with a walk and error. Kyle Vanderlinden singled in one run, with two more crossing on Jared Oser's base hit.
However, that was the last time UMB punctured the pitching of Bishop, who allowed only two more hits the rest of the game -- without letting a runner reach third base.
The Travelers took the lead in the top of the fifth when Darion Lawrence stroked a one-out single and rounded the circuit on a pair of wild pitches and a ground ball.
Right-hander Mason Paulus was dominant in the nightcap, yielding only four hits and striking out 11 batters. The lone run against him was unearned, Mitchell Harkman scoring on an error in the third.
Canaan Heinzler led off the Marshall second with a single and was knocked in by Anthony Inzunza's two-out single. The third began with Joe Damiano drawing a walk and Willis poking a single, both plated with two outs on Paulus' single and an error.
A lead-off walk to Devin Cott and two errors extended the Travelers' lead to 4-1 in the fourth, but it was the six-run sixth frame which put the game away.
A hit batter, Cott single and walk loaded the bases with one out. Trent Toliver got the only other hit of the inning, an RBI single, with four straight free passes and a fielder's choice roller forcing in the rest of the runs.
Jared Harris walked, went to third base on Cott's single and scored on a grounder in the seventh for Marshall.
Willis and Cott combined for four of the Travelers' eight hits during the game.
Marshall (12-6) will head north to Kirksville for two events this weekend. On Friday, the Travelers will meet Lutheran South of St. Louis -- the only one of the four teams the Owls didn't play during the MSHSAA Class 3 Championships earlier this month in Springfield -- in a showcase which will be part skills exhibition and controlled scrimmage.
Marshall will be in a pool with Macon and the host Tigers on Saturday during the first day of the Kirksville Wood Bat Tournament, which concludes Sunday with bracket play.
