Two of the National League’s best are set to meet on Tuesday in SoCal. After a brutal month of April, the Phillies (27-27) have rebounded under interim manager Don Mattingly. Following a victory on Monday, the Phillies are looking to earn their 14th win in 21 games. That may not come easy against a Padres (31-22) squad with World Series aspirations. San Diego, despite a middling +3 run differential, keeps eking out wins. Will that continue at home tonight in a potential postseason preview?

The Padres are favorites (-112) over the Phillies, with the over/under set at 7.5 runs. Below, I’ve laid out my preview, prediction, and best bet for Tuesday’s showdown between Philadelphia and San Diego on DraftKings Sportsbook.

Phillies vs. Padres prediction, preview

There may be no bigger x-factor on Philadelphia’s roster than Aaron Nola. At his best, the former All-Star is a borderline ace, capable of shutting down elite lineups. However, the right-hander has alternated good and bad days for most of the last two seasons. Through 50.2 innings in 2026, he’s recorded a ghastly 6.04 ERA, 1.56 WHIP and 51 strikeouts (9.1 K/9). That’s simply not up to par for a squad that fancies itself as title contenders. Savant implies that Nola has been a bit unlucky (4.77 xERA), but there’s nothing to suggest a turnaround is imminent.

If there was ever a time for the 32-year-old to get his act together, it’s tonight. Petco Park is a pitcher-friendly venue, and the Padres have been kind to opposing hurlers. The Friars are averaging 3.98 runs per game this season, seventh-worst in the majors. That number drops to just 3.63 when playing at home. In addition, San Diego has the third-worst OPS against right-handed pitching (.672). That’s due in large part to the struggles of Manny Machado (72 wRC+) and Fernando Tatis Jr. (89 wRC+). The latter, after 52 games played, still has yet to hit a home run.

On the other side, Randy Vasquez will get the nod tonight. It’s been a breakout campaign for the 27-year-old, a throw-in during 2023’s Juan Soto-Yankees deal in 2024. Once seen as a mere innings eater, Vasquez has managed to bring his average fastball velocity up to 94.9 MPH. Unsurprisingly, that’s led to improved numbers for the Dominican. Through 54.2 innings pitched, he owns a 2.96 ERA, 1.19 WHIP and 45 strikeouts (7.4 K/9). Even with added velocity, the righty is effective due to his superior command. A 7.1 BB% ranks within the top 71st percentile of all qualified pitchers.

If there’s a downside for Vasquez, his 5.44 xERA doesn’t look too hot. Without an ability to consistently make bats miss, the veteran relies on inducing weak contact. That may not pay dividends on Tuesday against a dangerous lineup. The Phillies haven’t been overwhelming at the plate recently, but this group can’t be slept on. It helps that they’ve shown a knack for crushing fastballs. Vasquez’s favorite pitches are the four-seamer (32%) and cutter (25%). When those offerings have been thrown at 95 MPH or slower, Philadelphia has notched a .264 batting average and .472 slugging percentage.

Phillies vs. Padres pick, best bet

As previously mentioned, Petco Park’s spacious dimensions can limit scoring. Still, it’s difficult to generate much confidence in either starter tonight. Nola has been a train wreck this season, getting rocked by just about every lineup in baseball. Vasquez’s progress has made for a nice story, but it feels like we’re waiting for the other shoe to drop. Philadelphia batters seem uniquely tailored to exploit his pitches as well. These lineups, filled with capable hitters, should manage to surpass seven runs tonight.

Best Bet: Phillies vs. Padres over 7.5 total runs (-108)
