Last Meeting ( Aug 18, 2018 ) Arizona 6, San Diego 7

The San Diego Padres ended a lengthy slide with a walk-off victory and look to earn a split of their four-game series when they host the Arizona Diamondbacks for the finale on Sunday. San Diego squandered a one-run lead in the seventh inning on Saturday before pinch-hitter Christian Villaneuva delivered a two-out RBI single in the ninth, ending the team's five-game skid.

Freddy Galvis went 2-for-3 with two RBIs in the 7-6 win as the Padres improved to 3-6 on their 10-game homestand. Paul Goldschmidt was 4-for-4 and drove in four runs as the top four batters in Arizona's lineup combined to go 11-for-17 with six RBIs and six runs scored. Goldschmidt is riding an 11-game hitting streak that includes seven multi-hit performances, four home runs and 11 RBIs. Saturday's loss ended the Diamondbacks' three-game winning streak as they fell to 4-4 on their nine-game road trip and remained just one-half game ahead of Colorado for the top spot in the National League West.

PITCHING MATCHUP: Diamondbacks RH Zack Greinke (12-8, 3.00 ERA) vs. Padres RH Brett Kennedy (0-2, 11.00)

After winning seven straight decisions, Greinke has lost three consecutive starts - including an outing at Texas on Monday in which he yielded four runs and six hits in 6 1/3 innings. It marked the first time the 34-year-old Floridian allowed more than two runs in 10 turns dating to June 18. Greinke, who gave up a total of three runs in his previous two outings, improved to 11-2 with two complete games and a 2.10 ERA in 21 career starts against the Padres when he permitted one run in seven frames on July 27 at San Diego.

Kennedy makes a third attempt at his initial major-league victory after surrendering 11 runs and 20 hits - four homers - over nine innings in his first two starts. The 24-year-old rookie from New Jersey demonstrated control, however, as he has issued just one walk while registering five strikeouts. Kennedy was superb for Triple-A El Paso this season before being recalled, going 10-0 with a 2.72 ERA in 16 starts.

WALK-OFFS

1. Villanueva was kept out of the starting lineup Saturday after being hit in the left foot with a ball in each of his previous two games.

2. San Diego LHP Eric Lauer (forearm) was sent to Single-A Lake Elsinore on Saturday to begin a rehab assignment.

3. Arizona signed RHP Randall Delgado, who was released on July 31 after going 2-0 with a 5.14 ERA in six relief appearances, to a minor-league contract on Saturday.

PREDICTION: Diamondbacks 6, Padres 1
