A top baseball prospect is set to make his major‑league debut, rendering him an attractive waiver‑wire candidate for Week 23. Additionally, several relief pitchers are poised to contribute saves, and two batters are riding strong hitting streaks. Below are five eligible players who remain widely available in Yahoo fantasy leagues.
Week 23 Waiver‑Wire Targets: Key Add‑Ons for Fantasy Baseball
George Lombard Jr., 2B/3B/SS (45% rostered)
Lombard was featured in this column two weeks prior, when his rostered percentage stood at 42%. Now, despite a strong major‑league debut — .292 batting average, two homers, and a .352 OBP across 14 games — he remains available in over half of leagues. Primarily the starting shortstop, he also qualifies at second and third base on Yahoo, making him a valuable add for any roster.
Alejandro Kirk, C, Toronto Blue Jays (45% rostered)
Catchers often experience fatigue during the late summer stretch, but Kirk — limited to 53 games due to injury — enters the stretch fresh. Over his last 23 contests he is 31‑for‑83 (.373) with a 1.016 OPS, indicating a potent bat. If your team needs a reliable catcher, Kirk presents an excellent waiver‑wire option.
Kade Anderson, SP, Seattle Mariners (39% rostered)
Drafted in the first round in 2025, Anderson dominated at Double‑A, posting a 1.06 ERA and 0.64 WHIP over 18 starts, with 135 strikeouts and just 47 hits in 93 ⅓ innings while walking only 10 times. The Mariners will promote him directly to the majors, slated to start against the Cubs on Saturday. Given his high strikeout potential, he should be a priority add in all formats.
Kodai Senga, RP, New York Mets (27% rostered)
After the Mets traded Luke Weaver and lost Devin Williams to a shoulder injury, Senga has assumed the closer role. Though his season ERA (7.82) and WHIP (1.68) are elevated, he has recorded a save in each of his last four appearances, three of which were scoreless. With Williams’ return uncertain, Senga offers a short‑term boost in saves for fantasy managers.
Ben Joyce, RP, Los Angeles Angels (21% rostered)
Joyce appeared in this column previously when his rostered percentage was just 7%. Since then he has posted consecutive save opportunities, establishing himself as the Angels’ preferred ninth‑inning option. Across six appearances since returning from injury, he holds a 0.33 WHIP and has struck out eight batters in six scoreless innings. Whenever the Angels have a save chance, Joyce is the pitcher they turn to.
Takeaway
The debut of Anderson makes him a prime target on the waiver wire across all fantasy baseball formats. Senga and Joyce are also worthy additions for teams needing saves in Week 23, while Lombard and Kirk provide bat‑side value. Continue to monitor our waiver‑wire updates throughout the season to maximize your league performance.
