The Phillies and Cardinals got started a little early, finishing up their four-game series on Thursday afternoon. In the evening, we have 10 games on our slate, including Cubs-Nationals.
The Cubs have jumped out to a 20-6 start, looking like baseball’s best — and scariest — team. Entering Thursday’s action, the Cubs have a +93 run differential (runs scored minus runs allowed). That’s by far the best in baseball. The next best are the Nationals at +50, the Mets at +44, and the Cardinals at +41. In fact, the Cubs’ run differential is so good that they have under-performed relative to their expected won-lost record of 22-4.
This is without Kyle Schwarber. This is with Jason Heyward hitting a miserable .211/.317/.256, Jorge Soler hitting .185/.276/.292, and Addison Russell hitting .224/.356/.329. It’s with John Lackey pitching to a 4.32 ERA.
What makes the Cubs so good? They’re on-base machines. The club’s aggregate .364 on-base percentage is second best in the majors behind the Pirates. Dexter Fowler has an outstanding .470 OBP and Anthony Rizzo is at an elite .403. In fact, of their regulars with 100-plus plate appearances, Heyward is the only one with a sub-.350 OBP. The league average is .319. The Cubs steal bases, too, as they’re 17-for-24 (~71 percent) in that department.
The Cubs have baseball’s best pitching staff, which has yielded a major league-best 2.54 runs per game. Only four teams are below 3.00 runs allowed per game. Of course, reigning NL Cy Young Award winner Jake Arrieta is the big contributor to that with a sterling 0.84 ERA, but Jon Lester has put up a 1.58 mark and Jason Hammel 1.24. Closer Hector Rondon has found himself in only four save situations but has converted each of them with an even 1.00 ERA and a 15/0 K/BB ratio in nine innings. The Cubs’ aggregate bullpen ERA of 2.66 is fifth-best in the majors.
It’s too early to use defensive statistics with any degree of certainty, but even the eye test shows the Cubs to be elite defenders at the important positions, particularly shortstop (Russell), right field (Heyward), and third base (Kris Bryant).
The Cubs’ success isn’t exactly surprising. The club rode five consecutive fifth-place finishes into some high draft picks and that talent is starting to establish itself in the majors. Whether it was fans, writers, or Vegas oddsmakers, the Cubs were preseason darlings.
