Taking a look at the San Francisco Giants’ projected starting rotation, the group appears to be in a strong position heading into next season following the additions of Tyler Mahle and Adrian Houser to an already solid foundation.

At the top of the rotation, the Giants are anchored by ace Logan Webb and veteran left-hander Robbie Ray, forming one of the more dependable one-two combinations in the league.

Webb, in particular, has established himself as one of baseball’s most consistent and reliable starters. Over the past three seasons, he has logged more than 600 innings, a rare feat in today’s game, while continuing to deliver high-level production.

In 2025, Webb posted a 15–11 record with a 3.22 ERA, 224 strikeouts, and a 1.24 WHIP, finishing fourth in Cy Young voting. There were no signs of regression, only further confirmation of his status as the rotation’s anchor.

Behind Webb, Ray provided the Giants with a much-needed stabilizing presence. At 33, Ray showed he was back on track last season, even if he did not fully replicate his peak years.

He finished 2025 with an 11–8 record, a 3.65 ERA, and a 1.21 WHIP, consistently giving the Giants quality innings. As San Francisco looks to remain competitive, Ray’s experience and dependability will be crucial moving forward.

The middle of the rotation features the Giants’ two newest additions in Mahle and Houser. Both signings align with the organization’s approach of avoiding long-term financial commitments unless tied to elite talent. While neither deal carries significant long-term risk, both pitchers have the potential to provide meaningful value.

Mahle carries the most uncertainty, largely due to durability concerns rather than performance. He was excellent when healthy last season, posting a 6–4 record and a 2.18 ERA, but injuries limited him to just 16 starts due to a right shoulder rotator cuff strain.

If Mahle can stay on the field, then he has the upside to be a major contributor, but availability remains the key question.

Houser’s concerns are more about consistency than health. Coming off a solid 2025 campaign in which he went 8–5 with a 3.31 ERA, his challenge will be maintaining steady production across a full season after a stronger first half than second.

Rounding out the rotation is likely Landen Roupp, who impressed in his role last season. Roupp posted a 7–7 record with a 3.80 ERA while throwing over 106 innings, showing flashes of becoming a reliable option.

With continued development, further improvement is well within reach as he looks to solidify his place in the Giants’ rotation.
