When I heard the White Sox were signing veteran left-handed pitcher Martin Perez to a one-year contract, my reaction was, "Ha! He's going to be the Opening Day starter!"
Perez, 33, is getting a guaranteed $5 million, according to reports. His salary for 2025 will be $3.5 million. The contract includes a $10 million mutual option for 2026, with a $1.5 million buyout.
What does the Sox rotation look like now that former ace Garrett Crochet has been traded to the Boston Red Sox for futures? Well, here are 10 pitchers we might see:
1. Perez. As ridiculous as it sounds, Perez is going to be the most accomplished starter on this team, which puts him in line for a potential Opening Day nod. His career record is 90-87 with a 4.44 ERA over 314 games, including 269 starts. He struggled the first half of 2024 with Pittsburgh, going 2-5 with a 5.20 ERA. But after a midseason trade to the San Diego Padres, Perez discovered new life over 10 starts. He went 3-1 with a 3.46 ERA. The lefty has a long track record of being a league-average starter, which makes him the top option on this Sox team.
2. Jonathan Cannon. The 24-year-old, former third-round draft pick was an afterthought coming into 2024, but he ended up making 23 appearances (21 starts) with the Sox and put up a 1.9 WAR season as a rookie. He went 5-10 with a 4.49 ERA. Among the younger pitchers who are candidates for the rotation, Cannon starts 2025 on the firmest ground.
3. Drew Thorpe. The 24-year-old righty was the centerpiece of the return in the Dylan Cease trade. After tearing up Double-A Birmingham, he was promoted to Chicago last season and made nine starts. Results were mixed, as he went 3-3 with a 5.48 ERA before elbow trouble sidelined him for the last two months of the season. If Thorpe is healthy, it's hard to envision him not being in the rotation.
4. Bryse Wilson. This 27-year-old veteran made 34 appearances with the Milwaukee Brewers last season, mostly in relief. But he did make nine starts in 2024, and I think he signed with Chicago believing he would get an opportunity to crack the rotation. I like his odds, just because it's hard to see the Sox going with Perez and four kids. There probably has to be one other veteran in there, and Wilson is probably that guy.
5. Davis Martin. The former 14th-round pick surprised everyone by giving the Sox about 60 respectable innings across 14 games (9 starts) in 2022, but then Tommy John surgery sidelined him for the entire 2023 season. He returned to mixed results in the second half of 2024. He made 11 appearances (10 starts) and tossed 50 innings with 47 strikeouts, going 0-5 with a 4.32 ERA. He just turned 28 years old, so there's not much upside left, but he probably enters spring with an inside track for a rotation spot.
6. Sean Burke. Another former third-round pick, the 25-year-old was another guy who was off the grid coming into 2024. He's been injured for a good chunk of his professional career, but he pitched himself back into the picture by making the most of his September call-up last season. He appeared in four games, three of them starts, and went 2-0 with a 1.42 ERA. He struck out 22 guys in only 19 innings. This is a staff that needs strikeouts. We'll see how Burke looks in spring.
7. Ky Bush. The 25-year-old lefty, acquired in 2023 in the trade that sent Lucas Giolito to the Los Angeles Angels, had a strong showing in Double-A Birmingham and earned an August look with the Sox. Alas, he struggled with his control, walking 16 guys in just 17.2 innings in the majors. He finished 0-3 with a 5.60 ERA. I would expect Bush to start the season in Charlotte, but it's not unreasonable to think he'll get another chance sometime in 2025.
8. Nick Nastrini. Speaking of control problems, Nastrini made eight starts and one relief appearance for the 2024 Sox. He walked 36 guys in 35.2 innings. That was enough to give him an 0-7 record with a 7.07 ERA. Ouch. The 24-year-old will probably get one more kick at the can to make the rotation this spring. It isn't as if the Sox are bursting at the seams with proven options, so there's still a chance for Nastrini to move up this list. But right now, I'm thinking whatever future he has might be in the bullpen.
9. Jairo Iriarte. Another pitcher who came to the Sox in the Cease trade, Iriarte got a late-season look in 2024 with six relief appearances. There's nothing wrong with his 1.50 ERA, but he walked eight guys and struck out six in six innings. Iriarte has a power arm, and he's never going to have great control. But he can't be *that* wild and expect to hold down a rotation spot. He's probably destined for Triple-A Charlotte to start the season, but a pitcher on the 40-man who has had a look in the majors can't be completely discounted.
10. Shane Smith. How about a Rule 5 pick? Smith made 32 appearances and 16 starts across two levels in the Milwaukee Brewers organization last year. He was 6-3 with a 3.05 ERA in those outings. He has to make the club out of spring training, or be offered back to the Brewers. So, that helps his odds, but the most likely scenario is he grabs a spot in the bullpen.
We'll leave top pitching prospects Noah Schultz and Hagen Smith off this list for now. They will start the season in the minor leagues, but I'll mention them here just to acknowledge that a 2025 debut isn't out of the question for either of them. I just don't expect it to occur in March or April.
