Jonah Heim hit a walk-off single to center to score Josh Smith and the Texas Rangers completed a three-game sweep of the Tampa Bay Rays with a 4-3 victory Sunday in Arlington, Texas.

Edwin Uceta (0-1) sat down the first two batters he faced in the bottom of the ninth before Smith hit a double to left. Two pitches later, Heim followed with his game-winner.

Corey Seager hit his first home run of the year for the Rangers, who’ve won eight of 10 to start the year. Marcus Semien and Leody Taveras added RBIs.

Smith finished 3-for-4 and scored two of the hosts’ four runs.

Rangers starter Kumar Rocker had a much better day after giving up six runs in three innings in his season debut last Monday at Cincinnati. Rocker scattered six hits over five innings of one-run ball Sunday, with one strikeout.

Jacob Webb (1-0) struck out two in the ninth.

The Rays trailed 3-1 through seven innings after Seager’s solo shot and Taveras’ RBI single. They tied the game in the eighth when Brandon Lowe hit a run-scoring grounder to first and Junior Caminero added a sacrifice fly.

Rays starter Drew Rasmussen went five innings, allowing a run on three hits and fanning four batters.

Kameron Misner added an RBI single early on for the Rays, who have dropped four in a row.
