Imagine a basketball team winning games because the bench players are scoring 30 points a night, while the three All-Stars on the roster can’t hit a shot. That’s basically what’s happening with the Arizona Diamondbacks right now.
Since coming back from the All-Star break (a mid-season vacation for players), the D-backs have been the hottest team in the National League. Let’s break down why this is so weird and wonderful at the same time.
IMPORTANT POINT: Run differential is like a report card for how dominant a team really is. If you win lots of close games, you might be lucky. But a +33 differential in just 18 games means they’ve been genuinely crushing opponents.
The biggest surprise? The catchers. Usually, catchers are known for defense first, hitting second. But James McCann and Gabriel Moreno have turned into offensive machines:
| Stat | Combined Total |
|---|---|
| Batting Average | .393 (that’s getting a hit almost 4 out of 10 times!) |
| Hits | 35 out of 89 at-bats |
| Home Runs | 5 |
| RBI (Runs Batted In) | 26 |
ELI5: What’s an RBI?
Imagine you’re at bat and your teammate is on third base. You hit the ball, they run home and score. That run counts as your RBI. 26 in 18 games is insane.
Here’s where it gets strange. The three guys supposed to carry the offense? They’re at the bottom of the team rankings.
| Player | Batting Avg | OPS | What’s Going Wrong |
|---|---|---|---|
| Corbin Carroll | .179 | .664 | Just not hitting the ball hard or often |
| Geraldo Perdomo | .179 | .659 | Walking a lot (good!), but zero power |
| Ketel Marte | .192 | .532 | No walks, no power, just… missing |
ELI5: What is OPS?
On-base Plus Slugging. It combines two things:
- On-base % — How often you reach base (hits + walks)
- Slugging % — How far you hit the ball (singles=1, doubles=2, HR=4)
Scale: .700 = okay, .800 = good, .900 = great, 1.000+ = MVP level
Marte’s .532 is really bad for a star player.
Since July 8th:
IMPORTANT POINT: All three slumping at the exact same time is statistically bizarre. It’s like your car’s engine, transmission, and brakes all failing on the same day.
Simple math: The "other 9 guys" are scoring nearly 6 runs per game.
Think of it like a group project where three kids do nothing, but the other seven kids work so hard they get an A+ anyway.
There are two possible futures:
If Carroll, Perdomo, and Marte return to their normal selves PLUS the role players keep producing → This team becomes nearly unstoppable. Like adding three All-Stars to an already-winning roster.
If the catchers and bench guys return to "normal" levels BEFORE the stars heat up → The offense could crater fast.
| What’s Happening | Why It Matters |
|---|---|
| D-backs 13-5 since break | Best record in NL, legitimately dominant (+33 run diff) |
| Catchers hitting .393 combined | Almost unheard of production from the catcher position |
| Star trio (Carroll, Perdomo, Marte) hitting terribly | All three in bottom 3 on team — extremely rare |
| Team averaging ~6 runs/game anyway | Depth is carrying the offense completely |
| Big Question: Will the stars join the party? | If yes → World Series contenders. If no → risky ride. |
They’re the Diamondbacks’ core offensive players. Carroll won Rookie of the Year in 2023. Marte is a two-time All-Star. Perdomo is a gold-glove shortstop who hit .280 last year. They’re the "faces of the franchise."
Every time a batter steps up to the plate counts as one — whether they hit, walk, get hit by a pitch, or make an out. It’s broader than "at-bat" (which excludes walks and sacrifice plays).
It’s incredible. The league average is around .240-.250. Over a full season, .393 would challenge the single-season record (.406 by Ted Williams in 1941). Over 18 games, it’s a hot streak — but 35-for-89 with 26 RBI is real production.
Two reasons: (1) He’s not walking (.231 on-base % is terrible), and (2) He’s not hitting for power (.301 slugging). Carroll and Perdomo at least get on base via walks. Marte is just… out.
Yes! The 2023 Diamondbacks made the World Series with uneven offense. But to win a championship, you usually need your best players playing like your best players. The current formula works for now — but it’s high-risk.
Final Thought: Baseball is a long season (162 games!). Hot streaks cool down, cold streaks heat up. The D-backs have bought themselves time with this incredible run. Now we wait to see if the stars show up for the second half.
