Mid-Week Waiver Wire Rankings: Fantasy Baseball Pickups for Week 20

August 13, 2026

Mid-week fantasy baseball waiver wire rankings for Week 20 (2026). Free-agent hitters and pitchers to add include Zack Gelof, Jacob Webb, Joshua Baez, Walker Jenkins, and Kade Anderson.

Amazingly, we are already halfway through August and Week 20. There is about a month and a half left in the season, giving us plenty of time to make that final push. At RotoBaller HQ, we return with more waiver wire advice with our mid-week fantasy baseball waiver rankings for Week 20—August 10 through August 16 — in leagues that allow daily moves. Our waiver wire list has been updated to include the top hitters and pitchers to add off the waiver wire.

This week we saw the Nationals promote lefty Jackson Kent from Triple-A Rochester, and he will make his MLB debut on Wednesday. The Yankees also called up reliever Bradley Hanner from Triple-A Scranton/Wilkes-Barre on Tuesday. Injuries continue to pile up as the Mets placed closer Devin Williams on the injured list with a right shoulder strain, while the Rangers put Nathan Eovaldi on the IL with elbow inflammation.

Fantasy Baseball Waiver Wire Pickups List

Since many fantasy baseball leagues have daily waiver-wire moves or multiple waiver-wire runs per week for adding players, this early-week rankings list should help you keep track of players emerging in the middle of the week before we reach Sunday. This article will guide you through our weekly ranking of the relevant waiver-wire pickup options, including how to prioritize them for your league (depending on the league size).

Waiver wire pickup options, including how to prioritize them for your league - depending on the league size:

Fantasy Baseball Waiver Wire Outlooks

Some of the top waiver wire names include Jacob Webb, Kade Anderson, Zack Gelof, Joshua Baez, Walker Jenkins, and more. Read some of the waiver wire outlooks below:

Jacob Webb, Chicago Cubs

Across 51 2/3 innings (52 games) in 2026, Chicago Cubs right-hander Jacob Webb has recorded a 4-2 record with a 2.44 ERA and 1.18 WHIP with 58 strikeouts and seven saves. With closer Daniel Palencia (elbow) on the injured list, the Cubs have largely taken a committee approach to the ninth inning.

Still, Webb has now earned saves in each of his last two appearances, both of which came after Chicago acquired right-hander Ryan Zeferjahn from the Los Angeles Angels at the trade deadline. Even with another high-leverage arm in the mix for the Cubs, Webb may be the team's preferred option.

The 32-year-old has posted a stellar 27.1% strikeout rate and has been one of Chicago's more reliable bullpen arms all season long. In deeper leagues, Webb carries waiver wire appeal for fantasy managers in need of stable ratios and some saves upside.

Zack Gelof, Athletics

Athletics infielder Zack Gelof (knee) was activated off the 10-day Injured List ahead of Monday's game against the Tampa Bay Rays. Gelof is ready to play after being sidelined since July 10 due to a right knee laceration. He'll cover third base and bat ninth versus right-hander Freddy Peralta on Monday.

Gelof figures to be the everyday third baseman down the stretch of the season. This season, Gelof is slashing .273/.327/.476 with 11 home runs, 29 RBI, and eight steals in 67 games. He could be an interesting deep league option given his power and speed upside.

Kade Anderson, Seattle Mariners

Seattle Mariners starting pitching prospect Kade Anderson tossed another shutout in his most recent outing at Double-A and remains the most dominant pitcher in the minor leagues. On August 7, Anderson tossed 5 1/3 innings, allowing just three hits, with no walks, no runs, and nine punchouts. This extended his current shutout streak to 15 innings (three starts).

During this stretch, the former LSU star has posted a 0.47 WHIP with a near-perfect 20:2 K:BB. On the season, the southpaw has held a 1.13 ERA with a 0.65 WHIP across his first 87 2/3 professional innings.

While Luis Castillo's move to Chicago did make Anderson's path to the majors clearer, the team has indicated he will remain a starter once promoted, so he may need to wait for another injury, as Seattle currently has a full staff. However, his upside on a per-game basis remains elite, and managers should continue to view him as a priority stash option across all league types.

Walker Jenkins, Minnesota Twins

Minnesota Twins outfield prospect Walker Jenkins turned in another dominant effort at Triple-A St. Paul as his MLB debut continues to loom closer. On August 8 (Saturday), Jenkins went 2-for-5 with a triple and a stolen base. Over his last 10 games at the top club in the Minnesota system, the former fifth overall selection has posted a .333/.391/.595 slash line with three doubles, two home runs and two stolen bases.

During this noted stretch, Jenkins has posted five multi-hit efforts and only gone hitless three times. On the season, Jenkins has appeared in just 57 Triple-A contests (due to injury), but has posted a sharp .838 OPS with six home runs and 11 stolen bases.

With the Twins competing for a Wild Card, expect them to turn to their top-ranked prospect in the near future to add another spark to the lineup, especially with Byron Buxton still on the shelf.

Joshua Baez, St. Louis Cardinals

St. Louis Cardinals outfield prospect Joshua Baez enters Week 20 as a top stash target, with a clear path to the major leagues. Ahead of the trade deadline, the St. Louis Cardinals parted ways with veteran corner outfielder Lars Nootbaar.

As a result, Baez faces even less competition for a spot on the MLB roster down the stretch. Additionally, the young outfielder has seen his production take another step forward, suggesting he could be on the verge of a call-up.

Over his last 15 games at the top club in the system (since July 21), Baez has posted a dominant .293/.354/.603 slash line with six doubles, four home runs and three stolen bases. On the season, he has gone deep 33 times and swiped 18 bags. His five-category upside makes him a must-stash ahead of Week 20.
