Fantasy Baseball Streaming Pitchers: Waiver Wire Pickups (Week 4)

Another week has come and gone, and it is time to look ahead to the upcoming fantasy baseball matchup. I will be here every week this season to give you suggestions on what pitchers you should stream to win your matchups.

I will be using the FantasyPros streaming pitchers rankings to help determine my picks. Feel free to sync your league and take a look at your own to find high-potential starters available on your waivers.

Also, please keep in mind that starters can get off schedule, and some projected starters can be pushed back due to circumstances such as injury and weather.

First, let’s take a look at last week’s picks:

Grant Holmes (vs. MIA): 4.0 Innings, 3 Strikeouts, 3 Earned Runs, 3 Hits, 2 Walks (No Decision)

Noah Schultz (vs. TB): 4.1 Innings, 4 Strikeouts, 3 Earned Runs, 3 Hits, 4 Walks (Loss)

Eduardo Rodriguez (@BAL): 5.0 Innings, 3 Strikeouts, 4 Earned Runs, 6 Hits, 4 Walks (No Decision)

Steven Matz (@CWS): 5.1 Innings, 4 Strikeouts, 2 Earned Runs, 6 Hits, 1 Walk (No Decision)

Total: 18.2 Innings, 14 Strikeouts, 12 Earned Runs, 18 Hits, 11 Walks (0-1)

This week, unfortunately, has room for improvement. Noah Schultz did not live up to the hype. Eduardo Rodriguez and Grant Holmes came back to earth. Steven Matz had a decent performance, but fell short of a quality start. Keep in mind this article is being written a little earlier than usual, and the later streamers have yet to pitch. Regardless, we can do better this week.

Week 4 Streaming Targets

Monday, April 20

Justin Wrobleski (SP – LAD) @COL | 5% Rostered

Justin Wrobleski is coming off a start where he held the Mets scoreless across eight innings. He allowed only two hits. The downside? He only struck out two batters. The Dodgers long reliever has been making turns through the rotation due to Blake Snell‘s shoulder injury, and is making a case to replace Roki Sasaki due to his 2.12 ERA and 0.76 WHIP.

Wrobleski has only had six strikeouts in 17 innings this year. His 13.6% whiff rate is one of the lowest among pitchers. The 25-year-old is getting hit much less hard as his average exit velocity has decreased from 92 miles per hour (the lowest percentile in 2025) to a greatly improved 87.4 miles per hour so far.

The lefty has been throwing his four-seamer much more frequently. It is two miles per hour slower on average, which has no doubt contributed to his decreased strikeouts and possibly has contributed to his lowered exit velocity.

Although Wrobleski may not get many strikeouts, I love him against the Rockies, who are only 6-12 and bat just .235 as a team.

Alternative: Michael McGreevy (SP – STL) @MIA | 9% Rostered

Tuesday, April 21

Mick Abel (SP – MIN) @NYM | 7% Rostered

Mick Abel has been finding some early success in his second season. The 24-year-old is coming off a spectacular start where he struck out ten Red Sox in seven scoreless innings. Abel struck out six Tigers in six scoreless innings in his start before that.

These back-to-back appearances have been a vast improvement over his first two appearances, where he allowed nine runs against the Rays and Orioles. The former highly-touted prospect has struggled in his first MLB innings, but now he appears to be settling in.

Abel primarily wields a mid-90s four-seamer and a changeup with increased movement and usage. This new pitch-mix has led to great success, so far. The Mets are a tough opponent, but Abel takes great momentum and a promising arsenal into the contest.

Alternative: Spencer Arrighetti (SP – HOU) @CLE | 8% Rostered

Wednesday, April 22

Eduardo Rodriguez (SP – ARI) vs. CWS | 25% Rostered

Eduardo Rodriguez finally had a not-so-good start. The expected stats said the lefty was due for some regression, and he allowed four runs against the Orioles in five innings. That being said, the 33-year-old remains a solid streaming option, especially against the White Sox, who are batting .195 as a team.

Rodriguez has found great success this year in limiting the launch angle of hitters. His average launch angle so far this season is 9.5 degrees, which is currently a career low. Rodriguez should continue to limit damage through ground balls against the White Sox hitters, where only Munetaka Murakami and Evan Pereira have a barrel rate above 20%.

Alternative: Janson Junk (SP – MIA) vs. STL | 2% Rostered

Thursday, April 23

Kodai Senga (SP – NYM) vs. MIN | 26% Rostered

Kodai Senga might have had the worst start of his MLB career against the Athletics. So, why would he be a good streaming option? Senga brings a track record of success, both in 2026 and in the years before.

Senga gave up seven runs to the Athletics. Before this, Senga allowed four runs across 11.2 innings, striking out 16. Senga has a harsh 7.07 ERA at the time of writing, but his xERA is 3.95. The main issue Senga has faced this season is getting hit harder. An increased exit velocity has decreased his ground ball rate from a great 47.6% in 2025 to 31.6% now.

The 33-year-old’s fastball is up two miles per hour from last season. His sweeper and sinker have inches more movement. His stuff seems good, and I am willing to say his implosion against the Athletics was the outlier, not the norm.

Start Senga against the Twins, who rank about average for hitting stats.

Alternative: Davis Martin (SP – CWS) @ARI | 7% Rostered

Friday, April 24

Will Warren (SP – NYY) @HOU | 23% Rostered

Will Warren is a solid option against the Astros. Will he blow the world away? Probably not. Still, he is a high-strikeout option available on waivers in most leagues.

The 26-year-old is having a great season. What I like most about Warren is his strikeout potential. He has a 9.7 K/9 ratio since his MLB career began in late 2024. Although Warren’s xERA of 3.74 compared to his actual ERA of 2.45 suggests he is getting somewhat lucky, he remains a great streaming candidate for strikeouts. Warren also possesses great win odds as a member of the Yankees’ rotation.

Warren may be taking a step forward after a decent 2025 rookie campaign. He has demonstrated great control so far, lowering his walk rate from 9.1% in 2025 to 7.5% so far this year.

Stream the righty against the Astros if you feel comfortable with a tough matchup.

Alternative: Noah Cameron (SP – KC) vs. LAA | 23% Rostered

Saturday, April 25

Ryan Weathers (SP – NYY) @HOU | 15% Rostered

Ryan Weathers allowed brutal back-to-back-to-back homers in his first inning against the Angels. He settled in after his shaky introduction, striking out ten, but he allowed another two runs across the next innings.

Why in the world would I suggest someone who just allowed five runs in five innings? Strikeout potential. Weathers has struck out 28 batters in 21 innings this season. He provides great value in points leagues, but perhaps should not be streamed in formats with ratios that can be blown up by bad starts.

Cautiously stream Weathers against the Astros.

Alternative: Jake Irvin (SP – WSH) @CWS | 1% Rostered

Sunday, April 26

Max Meyer (SP – MIA) @SF | 6% Rostered

Max Meyer against the Giants is a high-floor, low-ceiling stream. Meyer has been very average so far. His 4.12 ERA and 20 strikeouts over 19.2 innings are a great reflection of this. Meyer has yet to allow more than three runs in a start, but he has also yet to get a quality start.

Meyer was once a highly-ranked prospect, and he has yet to get it together. Maybe a healthy Meyer will flash more of his potential throughout the season. Meyer’s slider looks great this season, with a deadly 56.3% whiff rate. Meyer’s career trajectory is yet to be seen, but Meyer and his slider should flash more potential against the Giants.
