Mobile managed just four hits but made the most of them Sunday in whipping Chattanooga 8-1 for a fourth time in as many days.
The BayBears took control with five runs in the second inning, as two walks were followed by Raywilly Gomez's two-run double to center, Mike Freeman's two-run home run to right and Sean Jamieson's solo homer to left.
The Lookouts, who dropped to 16-27, took a 1-0 lead in the first inning on Erisbel Arruebarrena's homer to left, which was the first this season for the Cuban who signed a five-year, $25 million contract with the Los Angeles Dodgers in February.
Game five of a five-game series in Mobile is today at 12:35 EDT.
Garrett Gould (1-4, 5.79) is scheduled to start for the Lookouts, with Mike Lee (3-2, 3.42) scheduled for the BayBears.
