How does White Sox pitching staff look at start of 2026?

When people say the White Sox could get back to .500 in 2026, my standard response has been, "With what pitching?"

I think the Sox are lacking in both the starting rotation and the bullpen. Granted, the offseason is far from over, and there is still time to make additions before spring training begins in February. But as the calendar turns to 2026, let's take a look at where the pitching staff stands.

Starting rotation

If the season were to begin today -- and of course it does not -- here are the pitchers who would be most likely to land in the five-man rotation:

1. Shane Smith. The Rule 5 draftee made the All-Star Game in his rookie season, going 7-8 with a 3.81 ERA in 29 starts. On most teams, Smith would slot in as a No. 3 or No. 4 starting pitcher. However, on this Sox team, he looks like a reasonable bet to start on Opening Day. 

2. Davis Martin. The 28-year-old was mostly healthy for the first time since 2022 last year. He went 7-10 with a 4.10 ERA in 26 games (25 starts). Given that Martin was drafted in the 14th round in 2018, it's a development win for the Sox that he looks like a league-average pitcher when he's out there.

3. Anthony Kay. The 30-year-old lefty was added on a two-year, $12 million contract earlier this offseason. He hasn't pitched in the majors in two years, but he had a great year in Japan in 2025 -- 9-6 with a 1.74 ERA in 24 games. The Sox are hoping he's a sequel to Erick Fedde.

4. Sean Burke. The Opening Day starter in 2025 had an uneven year, going 4-11 with a 4.22 ERA in 28 games (22 starts). In fact, Burke was demoted to Charlotte for a time in 2025 before finishing the season in Chicago. That 1.444 WHIP is going to have to come down. Burke is not guaranteed a spot.  

5. Jonathan Cannon. Speaking of not being guaranteed a spot, if the Sox make another addition, Burke and Cannon might be fighting for the No. 5 spot in the rotation in spring. Cannon had a disastrous 2025. He went 4-10 in 22 games, and his ERA ballooned to 5.82. But he thinks he can bounce back.  

Other names to know include prospects Noah Schultz and Hagen Smith, both of whom remain in top-100 lists. Right-hander Tanner McDougal was added to the 40-man roster during the offseason. Righty Drew Thorpe and lefty Ky Bush are expected back sometime this season after Tommy John surgery.

Bullpen 

There should be heavy competition for the eight bullpen spots, but let's take a best guess:  

1. Grant Taylor. The hard-throwing 23-year-old appeared in 36 games as a rookie. He was impressive at times, recording six saves, and erratic and unlucky at other times. It all added up to a 4.91 ERA and 1.418 WHIP. The Sox say he will receive "multi-inning" opportunities in 2026.

2. Mike Vasil. The Rule 5 pick was one of the surprises of the 2025 campaign, totaling 101 innings in 47 appearances. He went 5-3 with a 2.50 ERA and totaled four saves while pitching in every role imaginable -- from starter to closer. Being versatile is one way to stick on a roster.

3. Sean Newcomb. The lefty signed a one-year, $4.5 million contract with the Sox earlier this offseason. There's been talk of letting him compete for a starting rotation spot. Sure, why not? But it's worth noting that Newcomb hasn't been a full-time starter since 2018. Of his 223 career appearances, 158 have been in relief.

4. Jordan Leasure. Somebody had to lead the 2025 Sox bullpen in saves, and it was Leasure with seven. He appeared in 68 games and went 5-6 with a 3.92 ERA. Notably, his WHIP in the second half of last season was 0.791, a drastic reduction from 1.618 in the first half. The Sox are hoping he pitches like he did late in the season. 

5. Brandon Eisert. Congratulations if you selected Eisert to lead the Sox in appearances in 2025. The lefty pitched 72 times, which I did not see coming. The results were mediocre, 3-8 with a 4.39 ERA. There's nothing remarkable about Eisert's platoon splits. He wasn't that great at getting lefties out. But availability is a skill, and Eisert was available.

6. Chris Murphy. This 27-year-old lefty has options left, but I figure the Sox didn't trade for him to bury him in the minors. He was 3-0 with a 3.12 ERA in 23 relief appearances with Boston last season. He was equally effective against both lefties (.597 OPS against) and righties (.598 OPS against).

7. Wikelman Gonzalez. The "fourth piece" of the four-player return from Boston in the Garrett Crochet trade pitched in 16 games with the Sox last season, going 1-0 with a 2.66 ERA. He totaled 20.1 innings in those games and seems suitable as a multi-inning reliever.  

8. Duncan Davitt. The Sox acquired Davitt from Tampa Bay in the Adrian Houser deal last summer, and then added him to the 40-man roster to protect him from Rule 5 last month. He started 28 games in the minors last year, but I don't think that's his role long term. Somebody has to be the long man, right?

It's worth noting that left-handers Tyler Gilbert and Bryan Hudson remain on the 40-man roster. Both are out of options, but how many lefties do you need? I see a competition brewing among Eisert, Murphy, Gilbert and Hudson for perhaps two roster spots. Prelander Berroa is working his way back from Tommy John surgery. Rule 5 draft selections Jedixson Paez and Alexander Alberto will also get a look in camp.

So, basically, I'm naming 13 guys for eight bullpen spots. I'd like to see another veteran added in both the rotation and the bullpen before spring training begins. If you listen to Sox podcasts, there's a lot of talk that more signings are coming. 

Let's hope so.
