Lahti set the tone by moving in front before the break, and that first-half edge shaped the rest of the contest. Mariehamn went into the interval chasing the game at 0-1, needing a response to change the flow. Instead, the visitors kept control of the score and added again after halftime, turning a narrow lead into a firmer advantage.
That second goal effectively settled the result. Mariehamn never found a way back onto the scoresheet, while Lahti saw out the remaining stages without surrendering their grip on the game. The split score across the two periods - one goal in the first half and one in the second - gives a clear summary of how the night unfolded.
For Lahti, the scoreline was built on steady progress rather than late drama. For Mariehamn, the home defeat was defined by an inability to answer once they fell behind. The final stats begin with the clean sheet and the two-goal margin, and those were the defining highlights of this Veikkausliiga meeting.
