Facing the slumping Marlins in Miami on Saturday, Kennedy is looking to make it victories in 10 straight decisions.
The Marlins have lost six in a row and are off to a shaky start after making a splash in the offseason unveiling their new park and signing several big names.
They send Anibal Sanchez to the mound, who has been very good but doesn't have much to show for his efforts. He notched a pair of no-decisions his last two times out, and has an ERA of 2.79.
He's looking to do what Kennedy did for the D-backs in his last start -- snap a losing streak. After getting swept by the Nationals (two games) and the Mets (three games) the Marlins dropped Game 1 of their series against Arizona and mustered only three hits on Friday.
Kennedy snapped the D-backs' five game-losing streak the last time he took the ball. He went seven innings and allowed three runs on nine hits to Philadelphia. Kennedy hasn't lost a regular-season game since Aug. 18, 2011.
He'll have plenty of support if the D-backs' offense produces like it did Friday night. Jason Kubel pounded out four hits and Lyle Overbay and Aaron Hill each had three.
D-backs: Miley stays in rotation
Left-hander Wade Miley will stay in the rotation and start Sunday against the Marlins, D-backs manager Kirk Gibson confirmed Friday.
Miley pitched out of the bullpen to start the season, but took the place of injured righty Daniel Hudson and tossed six shutout innings against the Phillies on Monday.
"It's self-explanatory," Gibson said of the move.
Gibson also said right-hander Josh Collmenter may be moving to the bullpen after struggling in the rotation to start the season.
Arizona is now 14-8 in its last 22 road games.
Marlins: Reyes gets 'break mentally'
Marlins shortstop Jose Reyes was out of the lineup Friday with what manager Ozzie Guillen called "more of a break mentally than physically."
Reyes is in the midst of a slump, hitting just .205 through the club's first 19 games.
"He was trying to do too much, and I think that's the reason he's struggling," Guillen said. "But it's not just Jose. There are a lot of guys on our club that are struggling right now. We're trying to come out of it the quickest we can. We're working on it."
The Marlins are 5-3 at home this season, but just 2-9 on the road.
Heath Bell has blown three saves already this season.
In two starts against the Marlins last season, Kennedy went 1-1, allowing eight earned runs in 13 innings.
The Marlins and D-backs have split their 52 meetings in Miami.
