The Humboldt Crabs hit a home run for the fourth straight game on Friday night, but defensive miscues let them down in a 7-2 loss to the Seattle Studs.
Ubaldo Lopez became the fourth different Crabs player to go deep in the opening week, hitting a two-run blast in the bottom of the second inning to tie the game at 2-2.
It remained that way until the seventh, when the visitors took advantage of some sloppy defense to score five unearned runs and pull away, and after that there was no way back for the Crabs, who fell to 2-4.
Dawson Bacho had the hot bat for the Crabs, finishing 3-for-4 with a double, while Kokko Figueiredo and Dom Souto each had a hit to round out a six-hit team performance.
Starter Josh Mollerus pitched six strong innings, allowing two earned runs on five hits and five walks, while striking out nine.
Jordyn Eglite took the loss in relief, giving up the five unearned runs on two hits and one walk.
Brennan Hancock hit a home run for the visitors.
The two teams will continue a three-game weekend series on Saturday night at the Arcata Ball Park.
First pitch is set for 7 p.m.
