This week at Fenway Park, the Boston Red Sox and New York Yankees will renew their rivalry for the first time in 2026. The Red Sox won the season series convincingly last year (9-5), but the Yankees got the last laugh in the Wild Card Series. They won the series in three games and became the first team to come back and win the Wild Card Series after losing Game 1.

"Every one is a big one for us," Red Sox catcher and former Yankees prospect Carlos Narváez told MassLive.com following Monday's win (BOS 8, DET 6). "Especially right now, but we've got a big one coming up (against the Yankees)."

The Yankees, despite a recent skid, enter this series with the American League's best record at 13-9. The Red Sox are 9-13 and in the AL East cellar at the moment. These two teams have a fairly front-loaded head-to-head schedule this year, and will see each other twice more before the All-Star break: June 5-7 in New York and June 25-28 in Boston.

RHP Luis Gil (0-1, 7.00) vs. LHP Connelly Early (1-0, 2.29)

LHP Max Fried (2-1, 2.97) vs. LHP Ranger Suárez (1-1, 3.22)

RHP Cam Schlittler (2-1, 1.95) vs. RHP Brayan Bello (1-2, 6.75)

On paper, the Yankees have the starting pitching advantage in two of the three games, but that doesn't mean a whole lot. Teams win games while being at the starting pitching disadvantage all the time, especially at Fenway Park, where weird things happen and odd bounces become extra-base hits. It certainly makes for entertaining baseball, especially when these two teams are involved.

Here now are four things to know going into this week's Yankees vs. Red Sox series in Boston, with a prediction thrown in because why not?

Schlittler, a Massachusetts native, dominated the Red Sox in Game 3 of the Wild Card Series last year, firing eight shutout innings with 12 strikeouts and zero walks. After that game, Schlittler said it had become "personal" because Red Sox fans attacked him and his family online prior to Game 3. Schlittler ended the Red Sox's season, then fired back on social media afterward:

Unfortunately, the personal attacks continue. Earlier this week, Schlittler told the New York Post he has received "some messages out there that are pretty unreal," including "death threats." He does not feel the messages have risen to the point that he has to get the authorities involved, however. For now, Schlittler's calling it trash talk that is starting to go too far.

"It's gonna be bad. It's gonna be bad," Schlittler told the New York Post when asked what he expects during Thursday's start. "I'm not nervous about it, but it's gonna be loud. They're gonna probably have dudes that are my age or a little bit younger, sitting right outside the bullpen yelling, whatever, probably throwing stuff at me, trying to grab me. That's kind of what I expect. So I know the guys are excited for it and I'm excited for it."

Power was a concern for the Red Sox coming into the season and things have certainly played out that way on the field. They've hit 13 home runs in 22 games, tied for the fewest in baseball with the San Francisco Giants. Willson Contreras leads the team with four home runs. Only seven Red Sox players have gone deep in 2026, and four of the seven have exactly one home run.

The Yankees, meanwhile, are third in baseball with 32 home runs in 22 games. Aaron Judge (nine) and Ben Rice (eight) are second and third in baseball in home runs and have out-homered the Red Sox by themselves, and not by a little either. Three other Yankees (Cody Bellinger, Trent Grisham, Amed Rosario) have at least three home runs as well.

There is more to life than home runs, though it is more difficult to score when you have to string together multiple base hits and walks in an inning to scratch out a run. The difference in power between these two teams shows up in their total offense:

1. Los Angeles Dodgers: 6.05 runs per game 2. Atlanta Braves: 5.70 runs per game ... 9. Yankees: 5.00 runs per game ... MLB average: 4.46 runs per game ... 20. Red Sox: 4.05 runs per game

The Red Sox have actually had a harder time scoring runs at home in the early going this year. They've averaged 3.90 runs in their 10 home games, versus 4.17 runs in their 12 road games. That's a tiny sample though. The overall lack of power? That is real. It looked to be an issue coming into the season and it has been an issue 22 games in.

Statistically, neither the Yankees nor the Red Sox has a bullpen advantage. Both bullpens rank middle of the pack and have had their ups and downs four weeks into the season. A big difference, at least heading into Tuesday's game, will be availability and rest. First and foremost, the Yankees had an off-day Monday. The Red Sox did not. That's advantage Yankees right off the bat.

Furthermore, the Yankees had blowout wins over the Kansas City Royals on Saturday and Sunday, and starters Will Warren and Ryan Weathers both went seven-plus innings. The Yankees used only low-leverage relievers over the weekend. Closer David Bednar hasn't pitched since Friday. Setup men Fernando Cruz and Tim Hill haven't pitched since the middle of last week.

The Red Sox, meanwhile, lost Sonny Gray to a hamstring injury in the third inning Monday. He'll undergo an MRI and is likely headed to the injured list. Manager Alex Cora had to use seven relievers to cover the final 6 ⅓ innings. Rule 5 Draft pick Ryan Watson was unable to protect a five-run lead in the ninth, which forced closer Aroldis Chapman into the game.
