NEW YORK -- Jose Acevedo struck out a career-high 10 in his first complete game, and Adam Dunn had three hits and drove in two runs as the Cincinnati Reds snapped a four-game losing streak with an 8-3 win over the New York Mets on Saturday night.

The Reds scored three times in the first inning en route to just their second win in nine games since the All-Star break.

Acevedo (2-0) was overpowering. He threw 111 pitches -- 81 strikes -- and struck out four straight in the fourth and fifth innings. He has won two straight since being recalled from Triple-A Louisville on July 18.

Acevedo, who threw seven scoreless innings and allowed only two hits at Milwaukee July 21, allowed three runs and five hits while walking two.

Dunn singled in the first, doubled to start the third and singled home two runs in the sixth for the Reds. The left fielder had been in a 5-for-47 slump.

Aaron Boone added two singles and two RBIs for the Reds.

The Reds, hurt by a 7.76 ERA in the first inning this season, finally had a big opening of their own, scoring three runs to shake up Mets rookie Aaron Heilman, who struck out five but gave up six runs and eight hits in 5 2-3 innings.

At times Heilman, who won his first major league game July 21, looked like the powerful pitcher that prompted the Mets to select him in the first round of the 2001 draft.

Heilman (1-3) started the game with two quick strikes to Jimenez, but his next pitch hit the second baseman in the back of the neck, setting up a big first inning.

After Dunn singled to center, Heilman struck out Jose Guillen and got Sean Casey to bounce out to first base. But Boone singled to center, scoring two. He scored on the next pitch when Mateo doubled to right-center.

Casey added an RBI single that scored Dunn in the third inning before the Reds broke the game open in the sixth.

Heilman showed some composure after walking Jason LaRue to start the sixth. Juan Castro dribbled a single under first baseman Jason Phillips' glove that pushed LaRue to third, and Castro went to second on Acevedo's sacrifice. But Heilman made several big pitches and caught Jimenez looking on a 3-2 count before lefty Graeme Lloyd came in to pitch to Dunn.

Dunn hit Lloyd's first pitch into right field for a two-run hit. Castro added a two-run homer in the seventh off of right-hander Edwin Almonte.

Acevedo tied his career mark in strikeouts by the fourth inning, when he struck out the Mets in order. He struck out Ty Wigginton on three pitches, got Vance Wilson swinging and fooled Joe McEwing on a called third strike, matching his high of seven, set Sept. 22, 2001, against Milwaukee.

Cliff Floyd got the first hit off of Acevedo, a line drive to dead center in the second inning that looked like Ruben Mateo would catch at the wall. Floyd slowed up as he neared second base, but the line drive went over Mateo's glove for Floyd's 17th home run of the year.

Notes: Phillips extended his hitting steak to 14 games with a third-inning single. … Jimenez had his 15-game hitting streak snapped despite scoring the Reds first run. The second baseman had hit in every game since being traded from the White Sox on July 6.
