BOSTON (AP) – Roy Halladay stopped Boston’s potent offense and spoiled Paul Byrd’s debut with the Red Sox, pitching his major league-leading eighth complete game in the Toronto Blue Jays’ 4-1 victory Saturday night.

The loss snapped Boston’s four-game winning streak and came after the Red Sox scored 37 runs in a three-game sweep of Texas.

Alex Rios hit a two-run homer and Adam Lind had a solo shot for the Blue Jays, who moved within eight games of Boston for the AL wild-card spot.

Halladay (14-9) improved to 10-4 in his last 16 starts, limiting the Red Sox to six singles before Dustin Pedroia’s homer leading off the ninth. He walked one and struck out four, holding an opponent to one earned run or less for the 13th time in 32 starts this season. It was his 39th career complete game.

Byrd (7-11), acquired Tuesday from Cleveland for cash or a player to be named, gave up hits to his first three batters – including Rios’ homer. Then he settled down to pitch 7 1-3 solid innings, allowing four runs and 10 hits without any walks or strikeouts.

After rolling past the Rangers, with the worst pitching staff in the majors, Boston hardly threatened against Halladay and the Blue Jays, who came in leading the AL with a 3.66 ERA.

Boston’s best chance came with two on and two outs in the first when J. D. Drew lined to center fielder Vernon Wells, who made a sliding catch.

Joe Inglett opened the game with a single, but was picked off by Byrd. Marco Scutaro then singled before Rios homered into the Green Monster seats for his ninth of the season.

Lind also homered into the Monster seats, making it 3-0 in the sixth. Wells’ RBI single made it 4-0 in the eighth.

Friday’s series opener was rained out and will be made up as part of a day-night doubleheader on Sept. 13.
