Rafael Devers drives a 12-3 onslaught as the Giants crest a four-game win streak against strong opposition, blasting a ground-rule double and a later homer while the lineup finally unlocks its power. Carson Whisenhunt fights through early trouble but settles in, and SF benefits from clutch hits from Dominic Smith, Matt Chapman, and a late surge from Ramos and Adames to bury the Cubs. The performance hints at 2026 readiness for a youthful, improving SF club.

Devers leads the way with multi-hit impact, boosting his OPS and showing a premium left-handed pop that can amplify SF’s approaching contention window. Chapman’s return to form and Smith’s productive at-bats compound the momentum, while Whisenhunt’s resilience offers a hopeful blueprint for a rookie adapting to major league pressure. The Giants look like a different club in the late season stretch, with implications for dynasty and fantasy futures.

Giants host Cubs at Oracle Park in Game 133 as Whisenhunt squares off with Rea. Whisenhunt carries a 4.91 ERA and 6.89 FIP across 18.1 innings, with 13 strikeouts and 9 walks, coming off a four-inning, two-run outing against Milwaukee. Rea owns a 3.96 ERA and 4.62 FIP over 127.1 frames with 93 K and 38 BB, last facing Milwaukee for five-plus innings with two runs allowed and five walks.

Week 20 of 2025 brings a well-defined waiver wire chorus for fantasy baseball rosters. Michael Wacha leads the shallow-league pool in Royals country, offering steady five-inning starts and a reliable path to wins without unsettling strikeout tallies. Cade Horton has seized his Cubs window with four straight quality frames and strong walk control, while Spencer Arrighetti anchors the Astros’ post-IL recovery, supported by a favorable xERA trend. Logan Henderson’s Brewers return and Nick Martinez’s bullpen-to-rotation versatility add depth, with Luis Severino re-emerging for the Athletics and providing a usable floor in multiple formats.

On the middle-to-deeper end, Slade Cecconi’s consistent, low-walk, five-innings-propensity profile makes him a smart pickup; Emmet Sheehan leverages a Dodgers rotation seat with improved miss rates; Jacob Lopez shows late-season swing-and-miss upside for the Athletics; and Justin Verlander, quietly, has posted a sub-1.00 WHIP over recent series and lands Washington and Tampa Bay in Week 20. Shane Smith’s White Sox continue to offer a usable floor, while Cristian Javier anchors the “other” bucket with solid strike-zone management.

Further down, Carson Whisenhunt, Cade Cavalli, Carlos Carrasco, and Hurston Waldrep are highlighted as longer-shot but intriguing targets in deeper leagues. Overall, active rosters should chase upside in Arrighetti, Horton, Sheehan, and Verlander while rotating in Wacha, Cecconi, and Severino for weekly streamability.

Carson Whisenhunt, the San Francisco Giants' No. 3 prospect, is set to make his MLB debut against the Pittsburgh Pirates on Monday at Oracle Park. This move follows the placement of pitcher Landen Roupp on the 15-day injured list due to elbow inflammation, alongside the demotion of Hayden Birdsong to Triple-A. Manager Bob Melvin expressed anticipation for Whisenhunt's arrival, noting his potential and the necessity due to current team injuries.

Whisenhunt, a second-round draft pick in 2022, has posted a 4.42 ERA in 97.2 innings across 18 starts with Triple-A Sacramento this season. With the Giants struggling with nine losses in their last 11 games and only two games above .500, Whisenhunt's debut comes at a crucial time in their pursuit of a wild card spot, currently three games behind the San Diego Padres.

The San Francisco Giants are taking a decisive step in their pursuit of a playoff spot by promoting their top pitching prospect, Carson Whisenhunt, for his MLB debut. Whisenhunt, a 24-year-old left-handed pitcher, has shown promise during his time in the minors, posting a 4.42 ERA and 7.9 strikeouts per nine innings in Triple-A Sacramento. Though he hasn't cracked MLB.com's top 100 prospects list, he is the Giants' most viable option amidst a challenging season.

Originally drafted in the second round out of East Carolina in 2022, Whisenhunt stands at 6'3" and 214 pounds, and has a striking minor league record with at least 10.8 strikeouts per nine innings at every level until now. His debut comes as the Giants look to invigorate their pitching staff and keep their postseason hopes alive as they face fierce competition in the National League.
