TORONTO – Vernon Wells and Gregg Zaun homered, and Josh Towers pitched into the seventh inning to lead the Toronto Blue Jays to a 6-4 victory over the Seattle Mariners.

Adrian Beltre hit his 19th homer for the Mariners, who have lost five of six. Beltre hit 48 homers for the Los Angeles Dodgers last season.

Towers (12-11) allowed four runs – one earned – and eight hits in six-plus innings, lowering his ERA to 3.78. He has reached career highs in wins, innings (192 2-3) and strikeouts 103.

The three unearned runs came in the first inning after first baseman Eric Hinske’s fielding error allowed Jeremy Reed to reach. Richie Sexson had an RBI single and Beltre followed with his two-run homer – his first since Aug. 20.

Jason Frasor pitched the ninth for his first save since Aug. 29, 2004, against the New York Yankees. Manager John Gibbons said struggling closer Miguel Batista wasn’t available because he pitched in the three previous three games.

Wells went 2-for-3 with a walk, a stolen base and two runs scored. He hit a two-run homer off Jeff Harris (2-5) in the first, cutting Seattle’s lead to 3-2.

Corey Koskie hit an RBI double in the fourth, and Russ Adams chased Harris in the fifth with a run-scoring double.

Harris dropped to 0-4 in September. The 31-year-old right-hander allowed four runs and six hits in 4 2-3 innings.

Zaun hit a two-run shot off Scott Atchison in the sixth to give Toronto a 6-3 lead.

Yorvit Torrealba chased Towers with a homer to lead off the seventh.

Notes: Manager Mike Hargrove made Sexson, usually the 1B, the DH so he could rest a sore knee. Hargrove didn’t want him playing on the artificial turf. Greg Dobbs replaced him at 1B. … Gibbons said Batista is still the closer despite being tied for the AL lead with eight blown saves. Batista blew a 4-3 lead in Monday’s 7-4 loss when Sexson hit a grand slam in the ninth.
