Series Preview: Mets Enter Enemy Territory for Philly Series

The roller coaster continues!

After taking a series from the Tigers, the Mets lost a critical series to the Cincinnati Reds. The games were there to be won, and New York had plenty of chances to do so. However, the Mets did not get it done.

Now, New York heads into the belly of the beast once again to take on the Phillies. If the Mets want to even have a slight chance at the NL East, they need to dominate the Phillies on their home turf. They need to play up to their competition, like they did at Citi Field, and not get blown off the field like they did last time they travelled to the City of Brotherly Love.

How do the Mets stack up in this series? And how will things shape up?

It is time for another Metsmerized series preview, this time covering the Mets’ trip to face their division rival. Without further ado, let us dive into it!

Pitching Matchups

Monday: Nolan McLean (4-0, 1.37 ERA) vs. Aaron Nola (3-8, 6.78 ERA)

• In his four major league starts, Nolan McLean has been one of the most impressive pitchers the Mets have had in a long time. The rookie is 4-0 with a 1.37 ERA and 38 strikeouts. When he is on point, McLean can seemingly strike batters out at will. He makes them uncomfortable in the box and commands the plate better than a good handful of veterans. Most impressively, though, has been his ability to work through trouble. In his last start against the Tigers, the rookie dealt with the most adversity he has faced all season. Detroit scored two runs early off him, and it looked like McLean may be in some trouble. But even without his best stuff, McLean battled and eventually found his groove, going six innings and striking out seven batters. The former two-way player truly brings something different to the mound for his starts, and expects that to continue in his second start against the Phillies. 
• Aaron Nola has not been himself this season. He is not going very deep into games, is giving up plenty of runs, and has struggled with giving up home runs at multiple points in 2025. Nola still can strike out batters at a good clip, as his past three starts have seen him strike out four batters or more. However, he has given up four runs or more in two of those starts. The Mets, to beat Nola, need to attack him early and get on the board early to set the tone for the series.

Tuesday: Sean Manaea (1-2, 5.60 ERA) vs. Ranger Suárez (11-6, 2.89 ERA)

• The 2025 Sean Manaea Experience rolls on! Despite striking out six batters in his start against the Tigers, the lefty gave up eight hits and five runs over 3.2 innings pitched. Manaea lost the zone on multiple key batters, leading to him giving up a large number of hits and two key home runs. Against Philadelphia, Manaea may have his last full chance to start games for the Mets in 2025. He needs to attack batters and focus on location, no matter how long he is in the game. New York needs the best version of Manaea, in whatever form that takes, to have a good chance to win this game. 
• As of now, Ranger Suárez is set to take the bump in game two of the series for Philadelphia. Suárez has been phenomenal once again in 2025 in every possible way. He is not walking batters at a high clip (5.7%), has a 98th percentile average exit velocity allowed, has generated chases at a 31.0% clip, and has avoided barrels all year.

Wednesday: Clay Holmes (11-7, 3.61 ERA) vs. Cristopher Sánchez (12-5, 2.60 ERA) 

• If there is one complaint to make about Clay Holmes, it is his command. That aspect of his game reared its ugly head against the Tigers; thanks to giving up three walks, Holmes allowed two earned runs and exited after 4.2 innings. Outside of his command issues, Holmes has done a good job limiting hard contact and blowup innings.
• The Mets beat Cristopher Sánchez once. They will need to do it again to have a chance to win this series. Sánchez has shut down almost everyone this season with a phenomenal sinker/changeup/slider pitch mix. He throws hard, strikes out a ton of batters, and keeps the ball on the ground when hitters make contact against him. The Mets won against Sánchez by being aggressive early in the count and making him work. While the pitcher will adjust and try to make things more difficult, the Mets need to stay the course and continue to attack early in this one.

Thursday: David Peterson (9-5, 3.72 ERA) vs. TBD

• In his most recent start against the Reds, the lefty gave up four runs on four hits over 5.1 innings pitched. Peterson did not have command issues in this one, but he only struck out one batter and generated only eight swing and misses. Since the calendar flipped to August, the lefty has not been the same “bulldog” that carried the Mets’ rotation through the early portions of the year. If it is not the command issues, Peterson is leaving too many pitches in the heart of the zone. At other times, Peterson randomly loses his command in the middle of what looked like a great outing. Against the Phillies, the Mets need Peterson at his best. He has the potential to do so, but the lefty will need to execute at a high level and break through the walls that have stopped him in this poor stretch.
• As of now, there is no listed starter for the Phillies in the last game of this series.

The (Other) Main Headline

New week, same story.

The Mets are still chasing consistency, and as I said last week, that is really all that matters for the rest of the season.

New York has shown the fire and ability to win against the best teams in the league, including the Phillies. However, they have also shrunken and been lifeless against multiple teams this season, like they did against the Reds this past weekend.

For the Mets to have any shot of being a legit contender and seal their playoff birth, they need to be consistent. If the rookie trio of Tong, McLean, and Sproat carries the bulk of the rotation, then one of Peterson, Manaea, or Holmes needs to find a better level of consistency. The same goes for the bullpen; the overall unit needs to find a way to buckle down in close games, even when the starting pitching is not perfect. And, arguably most importantly, the offense needs to ensure it continues to perform at a high level and doesn’t retreat to bad habits down the stretch.

If the Mets want to be in a great position, or even remain in a playoff spot, things have to be more consistent. At some level, some of their players just have to be better. New York is capable of it, but they need to display it on the field. They need to find that level that the 2024 Knicks showed down the stretch that allowed them to reach the Eastern Conference Finals. Growing pains are common in the beginning of the season, but now, it is firmly go-time.

Prediction

In their series against the Phillies, I see the Mets splitting the series in Philadelphia. 

On the pitching side of things, I see Nolan McLean helping the Mets earn a win and moving to 5-0 on the season. I also think that David Peterson will rebound, helping the Mets earn their second victory. 

At the plate, Pete Alonso will have two extra-base hits, Francisco Lindor will homer, and Juan Soto will have three RBIs in the series. I also think that Francisco Alvarez will have three hits in the series.

After this series, I have the Mets at 78-69 heading into what should be a fun series with the Texas Rangers.
