Peterson Isn’t Enough: Cubs Still Desperate for a True Ace
David Peterson and the Cubs’ Pitching Puzzle: What’s Going On in 2026?
Who Is David Peterson?
Think of David Peterson as a left-handed starting pitcher—the guy who stands on the little hill in the middle of the baseball diamond and throws the ball to start each play. He’s 28 years old and has been bouncing around the major leagues trying to find his groove.
In simple terms: He’s the "starter." His job is to pitch the first several innings of a game and keep the other team from scoring runs.
The Trade That Brought Him to Chicago
The Cubs didn’t draft Peterson—they traded for him. Here’s the deal:
- When: End of June 2026
- From: The New York Mets (their crosstown rivals… well, not really crosstown, but you get it)
- Cost: Minor league infielder Cole Mathis (a young player still developing in the minors)
- Hope: That Peterson could help fix the Cubs’ massive pitching problem
Important Point: In baseball trades, teams often swap "proven" players for "prospects" (young players with potential). The Mets gave up a current big-league pitcher for a future maybe-star.
The Numbers Don’t Look Great
Let’s look at Peterson’s report card so far this season. In baseball, we use something called ERA (Earned Run Average)—it’s the average number of runs a pitcher gives up over 9 innings. Lower is better.
| Stat | What It Means | Peterson’s 2026 Number |
|---|---|---|
| ERA | Runs allowed per 9 innings | 5.80 (yikes!) |
| Innings with Cubs | How long he’s lasted | 26.2 innings |
| Hits Allowed | Times batters reached base safely | 22 |
| Earned Runs | Runs that count against him | 15 |
| Home Runs | Balls hit out of the park | 4 |
Translation: A 5.80 ERA is not good for a starting pitcher. The league average is usually around 4.00–4.50. Peterson has been giving up runs like it’s a bake sale.
Why the Cubs Are Desperate for Pitching
Imagine trying to build a house but your hammer keeps breaking, your saw disappears, and your drill catches fire. That’s the Cubs’ pitching situation.
The Injury Bug Has Been Brutal
- More pitchers used than ANY other team in baseball this season
- Manager Craig Counsell (the boss in the dugout) has had his hands tied
- Pattern: One pitcher returns from injury → two more get hurt
- Recent blow: Jameson Taillon (another starter) was DFA’d (Designated for Assignment = cut from the team)
The Trade Deadline Clock Is Ticking
- Deadline: Monday, August 3rd
- The Cubs MUST add more pitchers before then
- But they can’t just wait—they need the guys already here to step up
The Rollercoaster: Peterson’s Best and Worst Moments
Peterson has been Dr. Jekyll and Mr. Hyde this season. Check out these two starts:
The High Point: July 21 vs. Detroit Tigers
- 6.2 innings pitched (that’s deep into the game!)
- 0 runs allowed (perfect!)
- Only time this season he’s done this
- Fans thought: "Maybe he’s figured it out!"
The Low Point: July 3 vs. St. Louis Cardinals
- 3 innings only (didn’t even finish the 4th)
- 10 runs allowed (TEN!)
- Final score: Cardinals 17, Cubs 1
- Fans thought: "Please make it stop…"
Callout: The Tale of Two Petersons
Same guy. Same season. Completely different results.
This inconsistency is what keeps Cubs fans up at night. Which Peterson shows up on any given day?
What Needs to Happen Next
The Cubs can’t keep running this experiment forever. Here’s the checklist for Peterson:
- Find consistency – No more 10-run disasters
- Eat innings – Go 5+ innings regularly so the bullpen (relief pitchers) doesn’t burn out
- Limit the long ball – 4 home runs in 26.2 innings is too many
- Trust his stuff – Stop nibbling at corners, attack the strike zone
Saturday’s Big Test: vs. the New York Yankees
This Saturday, Peterson takes the mound against the Yankees. Here’s why everyone’s nervous:
- Yankees lineup = scary good (lots of power hitters)
- One bad inning = game over (we’ve seen this movie before)
- Best case: 5 solid innings, 2 runs or fewer, Cubs offense supports him → WIN
- Worst case: 3 innings, 7 runs, bullpen exhausted for days → DISASTER
Fan Mood: "Edge of your seat" doesn’t begin to cover it. Cubs fans have seen this script too many times.
Summary
| Key Takeaway | Why It Matters |
|---|---|
| Peterson acquired in June for Cole Mathis | Low-cost gamble on a lefty starter |
| 5.80 ERA overall, rough 26.2 innings with Cubs | Not getting the job done consistently |
| Cubs using record number of pitchers | Desperation mode—every start matters |
| One gem (vs. Tigers), one disaster (vs. Cardinals) | Extreme volatility = unreliable |
| Saturday vs. Yankees = pivotal moment | Could determine if he stays in rotation |
Bottom line: The Cubs need Peterson to be a competent #4 or #5 starter. Right now, he’s a question mark with a giant flashing neon sign. The front office is surely scouting trade targets, but until help arrives, Peterson has to pitch better. Period.
FAQ: Your Questions Answered
Q: What does "DFA" mean when they said Jameson Taillon was DFA’d?
A: Designated for Assignment. It means the team removes him from the 40-man roster. They have 7 days to trade him, release him, or send him to the minors (if he clears waivers). Basically: he’s not on the team anymore.
Q: Why is a 5.80 ERA considered bad?
A: ERA measures runs allowed per 9 innings. The league average for starters is usually 4.00–4.50. At 5.80, Peterson allows roughly 1.5 more runs per game than an average starter. Over a full season, that’s dozens of extra runs—often the difference between playoffs and going home early.
Q: Who is Cole Mathis, and why did the Mets want him?
A: Mathis is a minor league infielder (plays 2nd base, shortstop, 3rd base). He was a 2nd-round draft pick with good hitting potential. The Mets liked his bat and versatility. For the Cubs, he was expendable because they have infield depth.
Q: Can the Cubs just send Peterson to the minors?
A: No. He’s out of minor league options (a rule limiting how many times you can shuttle a player up/down). If they remove him from the rotation, they’d have to DFA him (like Taillon) or trade him. They’re stuck with him on the big-league roster.
Q: What happens if Peterson bombs against the Yankees?
A: The Cubs will accelerate their trade deadline plans. They might:
- Move him to the bullpen (relief role)
- DFA him and eat the salary
- Make a bigger trade for a proven starter
- Call up a top pitching prospect (if one’s ready)
Final Thought: Baseball is a game of adjustments. Peterson has shown flashes. The Cubs need those flashes to become the norm. Saturday in the Bronx, we’ll see which version shows up.
