Starting Pitchers

Arizona is scheduled to start Corbin Burnes, who has worked only 10.1 innings and enters at 0-0 with a 7.84 ERA and 1.55 WHIP. He has allowed 12 hits and five home runs while recording eight strikeouts against four walks. San Diego counters with Walker Buehler, who is 9-6 with a 4.56 ERA and 1.34 WHIP through 150 innings. He has allowed 145 hits and 21 home runs while striking out 128 and walking 56. San Diego owns the statistical advantage, but the dramatically different workloads are important. Arizona's starter has such a limited sample that his numbers are more volatile, although allowing five home runs in just 10.1 innings is a significant early concern. San Diego's starter has provided a much larger body of work and enters with the better ERA and WHIP.

Diamondbacks Enter on a Five-Game Surge

Arizona enters Saturday at 85-74 and has won five consecutive completed games. The Diamondbacks swept their three-game road series against Colorado with victories of 7-2, 5-3 and 12-8 after finishing their previous series against New York with wins of 8-4 and 5-3. Arizona has scored 37 runs during the five-game winning streak, averaging 7.4 runs per contest.

The Diamondbacks are batting .246 with 717 runs, 1,315 hits and 162 home runs. Arizona carries a .317 on-base percentage and .402 slugging percentage. The pitching staff owns a 4.10 ERA and 1.27 WHIP with 1,118 strikeouts against 471 walks while allowing opponents to hit .248.

Arizona's recent offensive production is its biggest argument Saturday. The Diamondbacks have scored at least five runs in each game of their current five-game winning streak and have reached seven runs four times. Their concern is whether the pitching can hold up against a San Diego club that has also been swinging the bats well. Arizona's team ERA is slightly worse than San Diego's, and Saturday's scheduled starter has been hit hard in his limited work. The Diamondbacks may need another strong offensive performance to extend the streak.

Padres Have Been Excellent at Petco Park

San Diego enters Saturday at 89-70 overall and has won four of its last five completed games. The Padres are coming off consecutive road victories against Los Angeles by scores of 5-1 and 4-2 after losing the series opener 7-0. San Diego previously finished its series against Miami with victories of 7-3 and 7-6 in ten innings. The Padres have scored 23 runs and allowed 19 during that five-game stretch.

San Diego is batting .243 with 699 runs, 1,280 hits and 180 home runs. The Padres own a .318 on-base percentage and .397 slugging percentage. Their pitching staff has posted a 3.93 ERA and 1.29 WHIP with 1,295 strikeouts against 539 walks while holding opposing hitters to a .241 batting average.

The Padres' biggest advantages are their power, pitching depth and home performance. San Diego has hit 18 more home runs than Arizona and has recorded 177 more strikeouts on the mound. The Padres are also 49-29 at Petco Park, compared with Arizona's relatively modest 40-38 road mark. The overall statistical differences between these clubs are not enormous, but San Diego's combination of home-field performance and the more established Saturday starter provides a meaningful edge.

Arizona Diamondbacks vs San Diego Padres Picks and Prediction

Pick: San Diego Padres Moneyline

San Diego gets the moneyline selection in what projects as one of the more competitive games on Saturday's slate. Arizona's five-game winning streak deserves considerable respect, especially with the Diamondbacks scoring 37 runs during that stretch. However, San Diego is 49-29 at home and has won four of its last five itself. The Padres also have the more dependable starting-pitching profile Saturday, with their scheduled starter carrying a 4.56 ERA and 1.34 WHIP across 150 innings. Arizona's starter owns a 7.84 ERA and has surrendered five home runs in only 10.1 innings. With the season series tied 5-5 and the team statistics relatively close, San Diego's starting advantage and strong home record are enough to make the Padres the preferred side.

Pick: Over 8.0 or Lower

The over is the preferred total if the number is set at 8.0 or lower. Arizona has scored at least five runs in five consecutive games and has averaged 7.4 runs during its current winning streak. San Diego has also scored at least four runs in four of its last five contests. The largest concern for an under is Arizona's starting situation, as its scheduled starter has allowed 12 hits and five home runs in just 10.1 innings while posting a 7.84 ERA and 1.55 WHIP. San Diego's starter owns a 4.56 ERA, so neither starting profile demands an under despite Petco Park hosting the matchup. With both offenses entering in productive form, Over 8.0 or lower offers the better position.

Final Picks: San Diego Padres Moneyline and Over 8.0 or Lower
