OAKLAND (AP) — A.J. Griffin pitched six scoreless innings in his return to the Oakland Coliseum, Nomar Mazara had two hits and three RBIS, and the Texas Rangers beat the Athletics 7-0 on Monday night.Carlos Gomez and Mike Napoli added two RBIs apiece to help Texas end a three-game skid.Griffin (2-0) spent his first two seasons in the majors with the A’s before being released near the end of 2015 after Tommy John surgery a year earlier. He hadn’t pitched at the Coliseum since making his final start for Oakland on Sept. 18, 2013. He looked very comfortable in his return.The Rangers’ shaggy-haired right-hander allowed one hit and one walk, retired the final 14 batters he faced and finished with eight strikeouts — one shy of his career high.Three Texas relievers combined for the final nine outs to complete the three-hitter.It was a rough day all around for Oakland, which extended its season-high losing streak to four games.
