The Pittsburgh Pirates meet the San Diego Padres on Sunday, June 1, 2025, at Petco Park. The Pirates start lefty Andrew Heaney, while the Padres go with young Randy Vasquez. San Diego is favored around -140 at home, with the over/under at 9.0 runs. The Padres look to capitalize on home field and offensive momentum in this series finale.

Pitching Matchup Analysis

Pittsburgh sends veteran Andrew Heaney (3-6, 4.88 ERA) to the bump. Heaney has been inconsistent โ€“ at times flashing high strikeout ability, but often undone by the long ball (approx. 1.5 HR/9). In 62.2 innings, he has a high 1.40 WHIP and an 85 MPH exit velocity that suggests when heโ€™s hit, itโ€™s hard. Right-handed bats have given him trouble (Padres have plenty). On the Padres side, itโ€™s Randy Vasquez (2-1, 4.15 ERA). Vasquez, acquired from the Yankees, is a 24-year-old righty making his 6th start. Heโ€™s shown a lively mid-90s fastball and good breaking ball, though control is a bit shaky (4+ BB/9). At 1.35 WHIP in ~26 innings, heโ€™s been serviceable, and facing a Pirates lineup that is middle-of-the-pack could be a nice opportunity for him. This matchup is fairly even on paper. Heaney has more experience but is volatile; Vasquez is greener but has perhaps an element of unfamiliarity in his favor. The edge might tilt to San Diego given Heaneyโ€™s struggles on the road (ERA over 5 away) and the Padresโ€™ familiarity with him from his time with division rival Los Angeles. If Heaney is off, the Padres lineup could feast. Vasquez just needs to avoid walks and let the Pirates get themselves out. Slight nod to the Padres in pitching due to matchup and venue.

Key Factors (Park, Weather, Umpire)

Petco Park is typically pitcher-friendly, especially in the marine layer evening games. Day game on Sunday could see the ball carry a bit better (forecast ~72ยฐF, partly cloudy). Thereโ€™s a 7 mph breeze toward right field, minor effect. Petcoโ€™s spacious outfield could actually hurt Pittsburgh โ€“ the Padres have more team speed to leg out extra bases. If Heaney leaves pitches up, even at Petco, guys like Manny Machado and Xander Bogaerts can hit it out (Petcoโ€™s HR factor is about neutral nowadays). On the flip side, Pittsburghโ€™s power is modest; they rely on small ball and a couple of emerging bats like Jack Suwinski. Umpire considerations: If a pitcher-friendly ump is behind the dish, that could help Heaney nibble and Vasquez overcome his control issues. But no stark need to deviate from normal expectations. Both bullpens are decent: Piratesโ€™ bullpen ERA ~3.80, Padres around 3.50. However, the Padres have the elite closer (Josh Hader) if itโ€™s close. San Diegoโ€™s home crowd could also energize a Padres team trying to claw back into contention. All told, Petco might keep scoring in check somewhat, but if any starter falters early, the offenses have the talent to put up runs.

Team Trends (Last 5, Injuries)

The Pirates are 1-4 in their last 5 games, including losses in the first two of this series. Their offense in those five averaged just 3 runs/game. Theyโ€™ve particularly struggled against left-handed pitching, which could be a problem since many key Padres relievers are lefties. Pittsburghโ€™s rookie Henry Davis has been a bright spot, but overall the lineup looks a bit overmatched lately. The Padres are 4-1 over their last 5 and finally clicking offensively, averaging 6 runs in this win stretch. Juan Soto has been on a tear (2 HR, 7 RBI in the last week), and Fernando Tatis Jr. is impacting games with power and speed. Injuries: The Pirates lost Bryan Reynolds to the IL (wrist) last week โ€“ a huge hit to their offense. The Padres are relatively healthy; only utility man Ha-Seong Kim is day-to-day with a sore thumb, but likely to play. With Reynolds out, Pittsburghโ€™s lineup lacks thump and consistency. The over is 4-1 in San Diegoโ€™s last 5 games, thanks to their offense waking up. Pittsburghโ€™s lack of scoring has led to unders for them usually, but facing Vasquez could give them some chances. However, trends and talent side with San Diego continuing to score and likely winning by a margin.

Our Pick & Bet Recommendation

Our Pick: Padres 6 โ€“ Pirates 4. Weโ€™ll back San Diego on the run line (-1.5) for plus odds. The Padresโ€™ bats have a clear edge against Heaney if heโ€™s not sharp, and San Diegoโ€™s home record is improving. The Pirates missing Reynolds and slumping make it hard to trust them even with a +1.5 cushion. We do expect some runs, so Over 9.0 is a viable play as well. The Padres might cover most of that themselves if they get to Heaney (Pittsburghโ€™s team ERA the last week is over 5). One could consider the Padres team total over ~4.5 instead of full game over, to isolate their offense. But our recommended bet: Padres -1.5. San Diego has won 7 of their last 8 victories by 2 or more runs, indicating when they win, itโ€™s not often a one-run nail-biter. Meanwhile, Pittsburghโ€™s recent losses have often been multi-run. Combining that with the momentum and pitching matchup, a two-run Padres win is quite plausible. Play the Padres to complete the sweep in convincing fashion.
