Trey Gibson pitched brilliantly into the seventh inning and the Baltimore Orioles beat the Toronto Blue Jays 4-2 on Wednesday night to sweep a doubleheader and at least temporarily stay alive in the American League playoff race. One more loss by the Orioles — or a win by the Chicago White Sox, who lost 5-4 at Kansas City on Wednesday night — would eliminate Baltimore. The Orioles also won the opener 4-2 against Toronto, then the 24-year-old Gibson (2-3) was outstanding in the nightcap.
