(Betting Express) - Wins have been hard to come by lately for Toronto Blue Jays ace Roy Halladay, who will take the mound tonight in the opener of a three- game series versus the Seattle Mariners at Safeco Field.

Halladay is winless (0-1) over his last three starts since going unbeaten (5-0) in six previous trips to the mound. The 2003 AL Cy Young Award winner last took the hill on Wednesday versus Cincinnati, surrendering five runs and nine hits over 6 2/3 innings of a 6-5 setback.

The right-hander is 4-4 with a 3.00 earned run average in 12 career games, 10 of which have been starts, against Seattle.

Toronto has won two straight, three of four and five of its last seven games. It won the last two installments of a three-game series versus the Atlanta Braves at Rogers Centre, including Sunday's 1-0 victory. Alex Rios drove in Marco Scutaro with the lone run of the game on a sixth-inning double.

Jays starting pitcher A.J. Burnett was dominant through seven shutout innings, as he gave up only four hits while striking out 11 batters and walking four. B.J. Ryan then posted his 16th save of the season.

The Blue Jays will open a six-game road trip on Monday and are 18-24 as the visitor this season.

Seattle just swept the San Diego Padres in three games at Petco Park and has won five of the last six games. In a 9-2 victory on Sunday over the Padres, Adrian Beltre hit a two-run homer and knocked in three runs to power the Mariners to victory.

Ichiro Suzuki went 5-for-5, all singles, and scored twice for Seattle, which will begin a seven-game homestand on Monday night. Raul Ibanez and Jeremy Reed each finished with two hits and two RBI apiece for the Mariners, who had a season-high 18 hits.

Jeff Clement added a solo home run in the win, Seattle's eighth straight at Petco Park.

Erik Bedard was solid through 5 2/3 innings to earn the win for the Mariners. The left-hander allowed one run on three hits, while striking out three and walking three batters.

Taking the ball for the Mariners this evening will be R.A. Dickey, who is 2-3 with a 4.79 ERA in 12 games (4 starts) this season. He won his last outing on Tuesday against the New York Mets with an 11-0 blanking, in which Dickey hurled seven shutout frames of six-hit ball with five strikeouts and two walks.

The righty is 2-1 in five career games, two of which have been starts, against the Blue Jays.

Seattle won two of three games against Toronto at Rogers Centre from June 9-11. The Jays went 5-4 over the previous two seasons against the Mariners.
