2023 Fantasy Baseball Week 5 Waiver Wire

Welcome to the 2023 Fantasy Baseball Week 5 Waiver Wire.

This week on the Waiver Wire: Jarren Duran goes from deep league add to a must-add in just a week. Bailey Ober gets promoted to the big league squad just one week after being optioned. Lastly, my take on the Mitch Keller "breakout."

These three and three more 2023 Fantasy Baseball Week 5 Waiver Wire adds are discussed.

For our All-Access Members, an additional 28 batters and 17 pitchers are listed that can help you win your week!

2023 Fantasy Baseball Week 5 Waiver Wire

Top Waiver Adds

Bailey Ober, SP, Minnesota Twins

The Minnesota Twins announced Bailey Ober will get the nod and start Saturday, April 29, versus the Kansas City Royals. Fantasy managers did not have to wait long for Ober to get called back after the Twins optioned him on Monday, April 24. Expect Ober to stick in the rotation for at least a few weeks while Kenta Maeda is on the injured list.


Thus far in 2023, Ober has made four starts in Triple-A and one start in MLB. He's done well, and I fully expect that to continue heading forward. I wouldn't be surprised if Ober locked down a rotation spot even after Maeda returns. Pick him up and feel confident in doing so.

Jarren Duran, OF, Boston Red Sox

Jarren Duran was the deep league waiver wire add last week, but now he makes it to the top waiver adds after another stellar week. He's now played ten games in MLB this season.

First 5 Games.412.429.6470426152
Last 5 Games.389.421.6111154171

After looking at his stats for the first five and last five games, the biggest concern is the strikeouts. Duran is currently striking out 30% of the time. Despite this, he's still been successful at the plate, but Fantasy managers will want to keep a close eye on this. If it rises close to 40%, the production will surely fall.

Add Duran off waivers in 12-team leagues but watch his strikeout and hard-hit rates closely. Duran's statcast numbers show his hard-hit percentage is 64%. I believe this is unstainable, but if he can stay above 45%, he will have an extremely productive season.

Brent Rooker, OF, Oakland Athletics

If you need more reasons to sign up to be a Fantasy Six Pack All-Access Member, here's one. Brent Rooker was the DapScout Pick of the Week during the Week 3 Waiver Wire. You could've been in on Rooker two weeks ago before everybody knew about the slugging outfielder. Admittedly, I was skeptical of Rooker at the time, but I am sold now.

Now Rooker is a top waiver wire add after he continues smashing the ball. The Mississippi State product is tied with Jake Burger with the second-best barrel rate (15.3%) among qualified batters. Rooker also has the sixth-best expected slugging percentage (.647) and the 22nd-best expected batting average (.300). These tell me that Rooker can sustain his current slugging percentage (.695) and batting average (.305).

Don't be surprised when Rooker finishes the season with 35+ home runs.

Mitch Keller, SP, Pittsburgh Pirates

Stop me if you've heard this before. "Mitch Keller is finally breaking out. No, I'm serious, he is." I'm here to tell you that Keller is not breaking out. Instead, he is finding out who he is, and he is a good pitcher. He's not great, but he is good and Fantasy relevant.

Keller's two most significant improvements are his hard-hit rate (24%) and strikeout rate (26.8%). His career averages in these are 39.2% and 21.7%, respectively. These are both trending in the right direction.

How did he get here? Firstly, he added a cutter to his pitch mix, which is now his most used pitch. The best part about his cutter? It doesn't look anything like his other pitches, allowing him to be in control of the batter. Secondly, he dropped his slider. This has allowed him to throw the cutter as much as he has. Lastly, he looks extremely confident on the mound. It's hard to measure confidence, but if you watch Keller from previous years and compare him to this season, you'll notice the difference in his character.

For these reasons, Keller is an improved pitcher with high confidence and deserves to be rostered in Fantasy Baseball.

Ji Hwan Bae, 2B/OF, Pittsburgh Pirates

Ji Hwan Bae is in a six-way tie for the second most stolen bases (10). He racked up five against the Los Angeles Dodgers while starting catcher Will Smith was on the injured list.

His upcoming series is against the Washington Nationals and catcher Keibert Ruiz. Ruiz has only caught a base runner stealing twice out of 13 attempts. This is a low 15% and ranks 34th in baseball. After this series, they play the Tampa Bay Rays. The Rays' catchers have thrown out two of the seven base stealers they have faced this season. This looks like it will be another favorable week for the 23-year-old speedster.

Bae can do more than steal bases. He's slashing .254/.312/.366 with two doubles, two home runs, 15 runs, and nine RBI.

Now it's not like everything is going his way. Bae needs to do a better job at getting on base. The best way to do that is by shrinking the strike zone and walking more. His walk rate (6.4%) and strikeout rate (26.9%) are both in the 29th percentile among qualified batters.

Mauricio Dubon, 2B/SS/OF, Houston Astros

Mauricio Dubon made the Week 3 Waiver Wire in the shortstop sweepstakes section. At the time, his best-selling point was as a replacement for an injured shortstop. Now his best-selling point is that he is the leadoff man for the Houston Astros, who have scored the 11th most runs in baseball.

Since his first day as the leadoff man on April 15, he's scored 11 runs in 11 games while slashing .313/.333/.417 with three doubles, one triple, and two stolen bases.

My favorite part about Dubon's game is his incredible strikeout percentage (7.5%), the third-best among all qualified batters. Surprisingly, however, Dubon has the fifth-worst walk percentage (3.2%) among qualified batters.
