Sunday Fantasy Baseball Pitcher Streamers: Joey Cantillo Leads Top Waiver Wire Targets

Let's jump right in today and look at five starting pitchers in action on Sunday who are widely available in fantasy leagues and have good matchups. 

Most stats are from MLB.com, as are the probable starters. The full streamer rankings are listed at the bottom.

Joey Cantillo, Cleveland Guardians @ Texas Rangers

Cantillo has generally been an above-average strikeout pitcher who walks too many guys. Those trends have mostly continued in 2026, though his Ks are down and BBs are up from his career numbers. Cantillo does well limiting hits, runs, and home runs, so his main downfall is the lack of control, leaving nice upside but also plenty of downside when that touch leaves him.

Texas sits in or very close to the bottom 10 in essentially every offensive box stat, leaving them as a target nearly every day. That is especially true when they play at home, a major pitcher's park, which is where this game takes place. Lastly, the Rangers are just outside the top 10 in most batter strikeouts, setting a nice ceiling for opposing pitchers.

Cantillo is a mid-level streamer. The matchup is right, and Cantillo's career strikeout numbers give him a good ceiling, but there is also a little risk if his control isn't there, bringing him down just a hair.

Rhett Lowder, Cincinnati Reds @ St. Louis Cardinals

St. Louis may qualify as a bottom-10 offensive team right now, but they are closer to 20th than 30th in many stats, leaving them more below-average than truly bad. That makes them an OK target on the right days and against the right pitchers. The Cardinals don't strike out a ton, so they don't set a great ceiling, but there's a little value in going after this team.

Lowder is only 14 starts and 69 innings into his career, leaving it tough to deduce too much about what he will ultimately be. He came in with big hopes as a top-10 pick in 2023, but Lowder's numbers haven't been great, particularly in 2026. His walk rate is higher than average, and his strikeout rate is well below average, a bad start. On top of that, he has struggled with limiting hits and runs this season after doing better last year, though he has been fantastic with not giving up home runs.

Lowder is a low-level streamer. There's an expectation that things will get better given Lowder's pedigree, but it's tough to expect that until we really see it over any stretch. I'm still cautiously intrigued.

Connor Prielipp, Minnesota Twins vs. Kansas City Royals

Prielipp is another pitcher fresh into his career, as he has made his first eight starts this season. Prielipp has been OK, holding an above-average strikeout rate with just a few too many walks. He has also given up too many runs: 28 total (23 earned) in 39 1/3 innings. His other numbers aren't bad, so things could soon look up in that area if he can keep finding success elsewhere.

The Royals are another team in or near the bottom 10 in most categories, ranking high in doubles but not really anywhere else. Doubles are valuable, but they aren't the same as home runs, and Kansas City isn't doing enough else or stringing together enough hits to put runs on the board. KC is close to the bottom 10 in most strikeouts, so the ceiling isn't fantastic, but there's plenty of value in targeting the Royals.

Prielipp is a low-to-mid-level streamer. He could be argued to be a level higher because of his good strikeout work, but he has a very short track record, meaning it's better to show restraint in expecting too much.

David Sandlin, Chicago White Sox @ Philadelphia Phillies

Speaking of pitchers without much experience, Sandlin has made just two appearances in the major leagues, making starts the past two times through the rotation. Both outings came against the Twins, and it was a tale of two starts:

• May 27: 6 innings, 1 hit, 1 run, 0 walks, 4 strikeouts
• June 1: 4 innings, 8 hits, 8 runs, 4 walks, 4 strikeouts

It's best to expect this one to end up somewhere in the middle. He did good strikeout work in the minors, so there's some upside here, but it's tough to expect anything too much from such an inexperienced big-league player.

Every day that Philadelphia is listed here, I talk about how most of the team is faltering offensively. A few guys are doing their part, but players like Trea Turner, Alec Bohm, and J.T. Realmuto, among others, have labored hard, all failing to hit for average or power. The Phillies rank near the bottom in most offensive stats.

Sandlin is a low-level streamer. We saw some good and some bad in his first two starts, and it's too hard to know what to expect now to really trust him. There's some upside given his K work in the minors and the good matchup, but I'm staying away from this one so early in the season.

Randy Vasquez, San Diego Padres vs. New York Mets

Since we talked about the players on their division-mates in Philly, let's look at some individual Mets as well. Juan Soto is doing his thing; we can't argue with his results, only that he spent a little time on the IL. Francisco Lindor is on the IL now and was ineffective when in the lineup, and new additions Bo Bichette and Marcus Semien lead the team in at-bats but haven't hit for any power or average. There aren't many guys stepping up in any form for this New York team.

Vasquez has been strong limiting walks this season, but he has always been well below average as a strikeout pitcher, leaving him with a lower ceiling than we would like from our streamers. His Ks are a little better this year, and he has also done good work limiting hits, runs, and home runs, making him a valuable pitcher. The lower strikeout number is the only thing holding him back.

Vasquez is a low-to-mid-level streamer. I said it above: Vasquez is doing everything well except strikeouts, and even those numbers are better, so there's plenty of fantasy value here. He's not far from bumping up a level.
