OAKLAND — 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 A’s 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. The A’s had only five baserunners and one got past second base.

Before the game Oakland placed opening day starter Kendall Graveman on the 10-day disabled list with a strained right shoulder and announced that shortstop Marcus Semien will undergo surgery to repair a broken bone in his right wrist.

Texas opened the game with three consecutive hits off A’s starter Jharel Cotton (1-2) then pulled away with a four-run fifth.

Mazara had an RBI double in the first and a two-run single in the eighth.

The start of the game was delayed eight minutes due to rain, one day after the A’s home game against Houston was postponed due to weather.

Cotton allowed five runs over 5 1/3 innings. The right-hander retired 12 straight during one stretch but walked four batters, three of which scored.
