Pretty much everyone expected the Los Angeles Dodgers to be good in 2015, and their early season success hasn’t drawn as much attention as the surprises in New York and Houston or the total dominance in St. Louis. Yasiel Puig’s bout with a hamstring injury and Clayton Kershaw’s rare bout with humanity have in part overshadowed the club’s incredible offense success over the season’s first 30 games.

Check this out: The Dodgers’ .830 team OPS leads the Majors by more than 50 points, and ranks second among all affiliated professional clubs — behind only the Mets’ Class AAA team in Las Vegas, a famously fruitful hitting environment.

The average MLB club has scored 4.24 runs per game in 2015. It’s early yet, but that rate would be the highest in any season since 2012 if it holds, so it could be that the league in general is reversing the trend toward diminishing offensive output. And, unsurprisingly, the Dodgers’ offense has been buoyed to date by a bunch of small-sample performances that are likely unsustainable.

Still, they’re hitting like a team from bygone offensive eras, leading the Majors in homers and walks. No team has finished a season with an OPS higher than .800 since the 2011 Red Sox, and no club has maintained an OPS higher than the Dodgers’ current mark over a whole season since the world champion 2009 Yankees. And they’re doing it while playing their home games in Dodger Stadium, traditionally a pitcher’s park.

By OPS+, which adjusts for park and league, the Dodgers are at 128 after leading the Majors with a 110 mark in the stat in 2014. Once more, they’ve played only 30 games and they won’t likely hit like this all year. But few teams have ever topped a 120 OPS+ for a whole season, and none since the 1982 Milwaukee Brewers (with future Hall of Famers Robin Young and Paul Molitor in the lineup).

If they could somehow maintain it all season, the Dodgers’ current 128 OPS+ would actually eke out the 1927 Yankees record of a 127 OPS+ for the highest team total of all time.

Perhaps most amazingly, the Dodgers have done a lot of it without Puig, their best everyday player in 2014, and all of it without Matt Kemp — arguably their second best full-time hitter last season. They’ve benefited from hot starts up and down the roster, with regulars like Adrian Gonzalez, Joc Pederson and Howie Kendrick pulling big shares and role players like Justin Turner, Scott Van Slyke and Alex Guerrero providing huge boosts in part-time play.

On top of all that, the Dodgers will get Puig back eventually. Plus, highly touted Cuban infielder Hector Olivera should make his stateside debut sometime soon and may not need much time in the minors. And top prospect Corey Seager was recently promoted to Class AAA after torching Class AA pitching.

Things won’t always go this well for the Dodgers’ offense, of course, but that’s only because things have gone extraordinarily well for the Dodgers’ offense. And perhaps before the hitters cool off, Kershaw will return to his dominant form and the front office will sort out the uncertainty in the back half of their rotation.

The Dodgers may not have the league’s best record, but they’ve probably got the sport’s deepest roster and clearest path to the postseason. There’s still plenty of season to play, but the early success of their offense doesn’t seem outrageously surprising given the personnel and payroll. This is why everyone expected the Dodgers would be good this year.
