Jeremiah Jackson, Ryan Mountcastle and Samuel Basallo hit home runs, Trevor Rogers completed an unbeaten month of August with seven sharp innings and the visiting Baltimore Orioles turned the tables on the San Francisco Giants with an 11-1 romp Saturday afternoon.

Jackson also doubled, scored twice and finished with a season-best four RBIs while Daniel Johnson collected a double, single and three runs for the Orioles, who were thumped 15-8 in the series opener.

Riding a six-game winning streak, the Giants took the lead on Willy Adames' solo homer, his 25th of the season, in the bottom of the first.

Giants rookie Carson Seymour, making his first career start, took the 1-0 lead into the third, but two-run homers by Jackson, his second, and Mountcastle, his fifth, put the Orioles in the lead for good.

Seymour (0-2) was pulled at that point, charged with four runs on five hits in his three innings. He walked two and struck out two.

The visitors blew the game open in the fourth, a three-run uprising triggered by Basallo's first homer. The blast came in the catcher's 11th major league game.

An RBI triple by Jackson Holliday and sacrifice fly by Gunnar Henderson capped the inning's scoring that made it 7-1.

Dylan Beavers added an RBI single in the seventh and Jackson a two-run double in the eighth to help complete Baltimore's second double-digit scoring effort in exactly a month.

Having allowed one run in each of his previous five August starts, Rogers (8-2) made it six straight with seven innings of five-hit ball. He struck out five without issuing a walk.

The left-hander completed the month with a 4-1 record and 1.29 ERA -- amassing 41 strikeouts and six walks in 42 innings.

Mountcastle, Henderson and Beavers also had two hits apiece for the Orioles, who had lost five in a row and eight of nine. Mountcastle and Basallo scored twice each.

Andrew Knizner had a pair of singles for the Giants, whose highlight, other than Adames' homer, came in a nine-pitch, 1-2-3 ninth inning thrown by infielder Christian Koss.
