NEW YORK (AP) — Zack Gelof hit a two-run homer off Victor González in the ninth inning, and the Oakland Athletics stopped an eight-game losing streak in the Bronx by beating the Yankees 2-0 Monday following the ejection of New York manager Aaron Boone just five pitches in.

After New York’s Carlos Rodón and Oakland’s JP Sears matched each other with shutout ball, Abraham Toro reached off González (1-1) leading off the ninth when the pitcher slipped while trying to pick up his dribbler between the mound and the third-base line.

Gelof hit an opposite-field drive into the right-field seats on a flat sinker for his third home run this season.

“To see him go oppo on a lefty, a really good lefty, is a good sign,” A’s manager Mark Kotsay said.

Gelof had entered 3 for 19 against left-handers after hitting .167 (12 for 72) with one homer against them last year.
