In 2024 Chase Petty took that next step in his development and it paid dividends as he reached Triple-A at then end of the year. That helped him start the season with Louisville in 2025 where he had both ups and downs.

The season got out to a tough start for Chase Petty. Facing Omaha on April 2nd he allowed six runs on six hits and two walks in just 3.1 innings. Things went better over his next four starts as he posted a 1.37 ERA. Cincinnati then needed someone to come up and make a spot start against St. Louis in a doubleheader and it was Petty that got the call and things couldn’t have gone much worse as he allowed nine runs in 2.1 innings.

After that he returned to Triple-A where he rebounded with an 8-strikeout, 6-0 no-hit inning performance. The Reds called him up to the big leagues once again, this time for a road start in Houston and the results were better than his big league debut but not by a whole lot as he allowed four runs and walked six batters while giving up six hits in 3.0 innings.

Petty headed back to Louisville after that and his first two outings saw him give up four runs in 6.1 innings to Toledo. He followed that up by giving up just one run in 10.1 innings. Once again Cincinnati called him up, but this time they tried their best to not use him but had little choice in St. Louis as they went into the 11th inning and put him on the mound where he was charged with an unearned run in 0.2 innings.

Upon his return to Triple-A he allowed four runs in 9.2 innings in starts against St. Paul and Indianapolis. While he had struggled in MLB in three games, his ERA in Triple-A was at 2.93 and he had allowed just 40 hits in 55.1 innings while striking out 57 batters.

July 6th saw Petty take the mound on the road against Indianapolis and he allowed five earned runs in 2.0 innings. The next time out he allowed six runs in 5.0 innings before rebounding with a solid start against St. Paul. But that’s essentially how the rest of his season went. He would mix in the occasional strong outing, but follow it up with multiple clunkers.

That carried through the entire second half. In his third to final start of the year he allowed a run in 6.1 innings. Then he gave up six runs in 3.0 innings on nine hits before closing out the season by giving up eight runs in 1.1 innings. In his final 14 starts of the season he posted an ERA of 9.73 and gave up 83 hits in 57.1 innings while walking 33 batters and striking out just 45 of the 287 hitters he faced.

Chase Petty Scouting Report

Position: Right-handed pitcher | B/T: R/R

Height: 6′ 1″ | Weight: 190 lbs. | Acquired: Trade (Twins, 2022. 1st round pick, 2021) | Born: April 4, 2003

Fastball | He throws both a 2-seamer and a 4-seamer. His 4-seamer averaged 96 MPH and his 2-seamer averaged 94.7 MPH in 2025. His 4-seamer doesn’t have much rise to it and for some pitchers would move similar to a sinker, though in his case it’s got more rise and less run than his 2-seamer.

Slider | An above-average to plus offering when it is at its best. It works in the low-to-mid 80’s with good biting action.

Cutter | Another pitch that’s above-average to plus when at its best. It works in the 88-92 MPH range and also has some late action to it.

Change Up | An above-average pitch that works in the mid-to-upper 80’s.

The 2025 season was one of two halves, at least when it comes to the minor leagues for Chase Petty. His success and struggles in the two halves saw him be quite a different pitcher. Let’s take a quick look at how his pitch usage and the subsequent results were in his time in 2025 in Triple-A:

4-sm2-smcuttersliderchangeERAH/9IP1st 1222%23%30%11%15%2.936.51last 1413%31%17%20%19%9.7313.03

The only pitch that didn’t see a bit change in usage was the change up. His other four offerings saw him make big changes in how frequently he used it and the results were disastrous. His ERA more than tripled and his hit’s allowed per 9-innings doubled. The walks were up and the strikeouts were down.

We can’t be certain that his pitch usage changes are the only reason he fell apart in the second half of the season. But it certainly seems that there’s some connection here, though it is also worth being up front that except for his slider all of his pitches were hit significantly more in the second half than they were in the first half.

It’s also worth noting that his final two outings of the year saw a big drop off in velocity. In the 10 starts before his final two of the year he averaged 96.4 MPH with his 4-seamer, 95.0 with his 2-seamer, and 89.1 with his cutter. In the second to last game of the year he averaged 94.6 with his 4-seamer, 92.9 with his 2-seamer, and 87.2 with his cutter. The final start saw the 4-seamer drop to 92.9 MPH, while the 2-seamer was at 92.8 and the cutter at 87.3. That kind of velocity drop off is usually something that would be very concerning. It’s worth keeping an eye on in spring training in 2026.

Consistency was a big issue in 2025. For the first time in his career Petty struggled with throwing strikes. But it wasn’t just throwing strikes that were the problem, he also saw struggles locating within the zone at times – particularly in the second half.

When everything is going right for Petty he’s got good control and solid command (control is the ability to throw strikes, while command is the ability to hit specific targets in the zone). And he’s able to throw four or five above-average pitches depending on how you feel about the fastball. That’s the guy that showed up in the previous two years a lot more often than the guy who showed up in 2025.

There’s still a lot of upside for Petty. He’s won’t turn 23 until the second week of the regular season. But after taking steps forward for several years in the past, his 2025 was a step in the wrong direction in multiple ways. Petty and the organization have to figure out what it was that led to his second half spiral, and also how to get him to take that next step to find success in the big leagues. The pieces are all there from a stuff perspective. He’s shown better control and command in the past. It’s now about putting all of those things together.
