ARLINGTON, Texas (CBSDFW.COM/AP) — Tim Federowicz homered in his first big league game this season, Nomar Mazara also went deep and the Texas Rangers beat the Oakland Athletics 10-5 in the opener of a day-night doubleheader Saturday.

Texas went ahead to stay with a three-run first off Paul Blackburn (0-1), who was called up as Oakland’s 26th player for the doubleheader after being in Triple-A Las Vegas all season. The right-hander gave up five runs in three innings.

Matt Olson and Josh Phegley homered for the A’s. Phegley also had a two-run double, on the first pitch he faced in the fourth when taking over with a 2-2 count after catcher Nick Hundley left the game.

Mazara’s two-run homer in the third, his ninth of the season, put Texas up 5-0. He also had a sacrifice fly in the first before Asdrúbal Cabrera’s two-run single.

Federowicz, the catcher who had been with Cleveland’s Triple-A affiliate, was acquired in a trade Friday and added to the Rangers roster after Isiah Kiner-Falefa was put on the 10-day injured list. His three-run homer in the fifth was his ninth career homer, in 135 games over seven seasons and now with his sixth team. He also had a double and walked.

Palumbo struck out four without a walk while allowing four runs and six hits.

Phillips Valdez, the third Rangers pitcher, also made his major league debut with two scoreless innings after being added as their 26th player. The 27-year-old right-hander appeared in 214 minor league games over 10 seasons.

The second game of the Saturday doubleheader starts at 8 p.m. at Globe Life Park.
