Luke Landrus belted a grand slam Monday afternoon, helping the Charleston Trojans post an 8-5 victory over St. Anthony at Evergreen Hollow Park.

The loss knocked the Bulldogs from the unbeaten ranks after opening the spring season with 11 straight wins.

The Trojans took the lead with a six-run third. They had five of their eight hits in the inning, along with a walk and a hit batter. Landrus capped the inning with a bases-clearing blast that sailed over the rightfield fence.

Charleston added two runs in the fourth and carried an 8-0 lead into the bottom of the seventh. But the Bulldogs refused to go quietly.

Brody Niebrugge started things with a walk and scored on an RBI double by Will Hoene. Angelo Mendella walked and Eli Levitt followed with a double to drive in the second run. Logan Antrim added an RBI single and runs scored on a ground ball and an error.

St. Anthony had two runners on base and just one out, but the final two batters were retired to end the rally.

Niebrugge pitched the first three innings and took the loss. He allowed five hits and six runs, while walking three and striking out two. Colton Fearday, Seth Hotze and Levitt also pitched in the game.

The Bulldogs, now 11-1, will face Effingham in the City Series on Wednesday, Thursday and Friday. Effingham will host games on Wednesday and Friday at Paul Smith Field and the Bulldogs will host Thursday’s contest at Evergreen Hollow Park. Game time is scheduled for 7 p.m. each day.
