Paul Skenes’ Velocity Drop and Early Exit: What’s Going On with the Pirates Ace?

What Happened in Tuesday’s Game?

Imagine you’re watching your favorite pitcher dominate, but suddenly the manager pulls him way earlier than usual. That’s exactly what happened Tuesday night when the Pittsburgh Pirates played the Miami Marlins.

Paul Skenes—the Pirates’ star pitcher and last year’s National League Cy Young Award winner (that’s the trophy for the best pitcher in the league)—was taken out of the game after throwing only 65 pitches. For a starting pitcher, that’s really early. Most starters throw 90–100+ pitches.

Here’s the quick rundown:

• Result: Pirates lost
• Skenes’ line: 5 innings, 2 runs allowed (1 earned), 5 hits, 1 walk, 4 strikeouts
• Pitch count: 65 (tied for his second-lowest in a start lasting 5+ innings this season)
• Record after the game: 9–11 on the season

Important Point: Manager Don Kelly insisted this wasn’t about injury. He said he pulled Skenes because he "thought it gave us the best chance to win." Skenes agreed with the decision, even joking, "If I were the manager, I’d probably do it too."

The Velocity Numbers: A Clear Drop

Velocity = how fast the ball travels. For a power pitcher like Skenes, velocity is everything. And right now, it’s down—way down.

Skenes’ Average Fastball Velocity by Year

Tuesday’s Game: A Career Low

• Average fastball: 95.7 mph (lowest of his career)
• Hardest pitch: Didn’t reach 97 mph even once
• Whiff rate (swing-and-miss percentage): 12% — the worst single-game mark of his career
  • Translation: Batters barely missed his fastball. They squared it up.

What the Manager and Player Said

Don Kelly (Manager)

"It’s tough. Everybody is going through it. We need to keep grinding and find a way. It’s frustrating for everybody. When you’re going out there and battling for something, there is different pressure."

Paul Skenes (Pitcher)

"[Kelly] walked me through everything, and it made sense. I wish I could have gone more, but it kinda is what it is."

Skenes also hinted at two possible reasons for his struggles:

1. Changes in his routine — he mentioned "changes" but didn’t specify
2. Pitch volume — not total innings, but stressful innings
   

   "I think I’ve probably had more 30- to 35-pitch innings this year than I have probably in the last two years combined… That’s probably part of it too."

Key stat: Skenes has a 3.88 ERA in 134⅔ innings this season. That’s not bad overall—but in his last 9 starts, he’s 3–4 with a 5.79 ERA. That’s a rough stretch.

Why Is This Happening? (The Leading Theories)

Baseball folks love to speculate. Here are the main ideas floating around:

1. Workload & "Hidden" Volume

• Skenes’ innings total (134⅔) isn’t huge
• But high-pitch innings (30+ pitches in a single inning) are exhausting
• Think of it like sprinting vs. jogging: 100 pitches over 7 easy innings ≠ 100 pitches over 5 stressful innings

2. Mechanical or Routine Tweaks

• Skenes said there were "changes" in his routine
• Even small adjustments to delivery, warm-up, or recovery can throw off velocity

3. The "Sophomore Slump" Effect

• Hitters have a full year of video on him now
• They’re laying off his chase pitches, forcing him to throw more strikes = more pitches = more fatigue

4. Not Injury (Per the Team)

• Both Kelly and Skenes said no injury
• But velocity drops can be early warning signs—so fans are nervous

What This Means for the Pirates

The Good News

• Skenes is still striking guys out (4 K’s in 5 innings Tuesday)
• His overall ERA (3.88) is respectable
• He’s mature beyond his years—handling the hook professionally

The Concerning News

• Velocity trend is downward for 3 straight years
• Whiff rate collapsing (12% Tuesday = batters not fooled)
• Recent ERA (5.79 over 9 starts) looks like a different pitcher

What Happens Next?

1. Monitor his next start — will velocity bounce back?
2. Watch pitch counts — will the Pirates limit stressful innings?
3. Check for routine adjustments — is the training staff tweaking things?
4. Listen to the player — Skenes is usually honest about how he feels

Summary

Bottom line: Paul Skenes is still really good. But he’s not dominant right now like he was in 2024. The Pirates need him to be dominant for a playoff push. The next few starts will tell us a lot.

FAQ

1. Is Paul Skenes injured?

The Pirates say no. Both manager Don Kelly and Skenes himself said the early exit wasn’t injury-related. However, velocity drops can sometimes signal something physical, so fans and analysts are watching closely.

2. Why does fastball velocity matter so much?

For a "power pitcher" like Skenes, his whole game is built on overwhelming hitters with speed. When velocity drops:

• Hitters have more time to react
• His off-speed pitches (slider, changeup) become less effective because they’re not as different in speed
• He gets fewer swing-and-misses (whiffs)

3. What’s a "30- to 35-pitch inning" and why is it bad?

A normal inning might take 10–15 pitches. A 30+ pitch inning means:

• Lots of batters came to the plate
• Lots of foul balls, deep counts, or runners on base
• The pitcher works way harder than the inning count suggests
• It’s like doing sprint intervals instead of a steady jog

4. Has Skenes ever gone through a slump like this before?

Not really. In 2024 (his rookie year), he was dominant from day one. This is his first extended rough patch in the majors—which is partly why it’s getting so much attention.

5. What should Pirates fans watch for in his next start?

Three things:

1. First-pitch velocity — is it back near 97–98 mph?
2. Pitch efficiency — can he get through 6+ innings on < 90 pitches?
3. Swing-and-miss rate — are hitters missing his fastball again?
