Mendy’s Pitching Streamers Week 5: May 2nd – May 5th

Welcome to David Mendelson’s Weekly Starting Pitcher Streamers for the week of May 2 – May 5.

It’s cool writing an article like this every week where you get to see pitchers graduate from your column. Players like Kyle Wright, Mackenzie Gore, Jesus Luzardo, and others have all gotten to the point where they are no longer considered streamers even in the shallowest of leagues. People take note of changes these pitchers have made early on in the season, and rostering players like these could end up being a league-winning move.

Sometimes, your draft doesn’t work out how you intended it to. Whether it be injuries, lack of performance, or maybe your draft was just awful. At some point, you’re going to need to pick up pitchers off the waiver wire and stream them (in other words pick them up for a start or two). This becomes crucial as hitting on the right pitchers consistently will help your ratios, while also potentially beating an opponent for those that play in H2H formats.

So how do we determine which pitchers to stream? Well, there are a lot of ways but I’ve found a few ways to be most effective. This can include looking at the trends of the opposing teams over recent periods of time, how they’re faring against certain handiness, and of course, how that streaming pitcher is currently performing.

I’m here to try and help you narrow it down to five names from all games Monday – Thursday every week, my goal all season being to provide you with the BEST pitching streamers each week to hopefully help you when you’re in a pinch. It’s important to remember that I won’t always be right (no one is), but I hope to provide you with winning streamers more often than not. The criteria for being in this article? The pitcher must be rostered in 50% or less of leagues on FantasyPros (the site being referenced for these articles).

This article will go out every Sunday morning so make sure to make necessary adjustments with postponements, starts skipped, IL stints, etc affecting the projected pitcher starting. The hope for these articles is to keep having more data that we can build off of as the season moves along.

With that being said, here are some factors that go into my streaming picks:

Percentage Rostered – Pitcher must be rostered in 50% or fewer according to FantasyPros to qualify for this article.

wRC+ of Opposing Team – wRC+ or Weighed Runs Created Plus, takes the statistic Runs Created and adjusts that number to account for important external factors — like ballpark or era. It’s adjusted, so a wRC+ of 100 is league average and 150 would be 50 percent above league average. This is one of my favorite stats to look at when picking not just pitching, but hitting as well.

Home/Road ERA Splits – How a pitcher does at home versus how they do on the road. The biggest example of this is someone like German Marquez and how he pitches on the road compared to at Coors Field.

Other Analytics – Things like a pitcher’s swinging strike rate, K-BB ratios, ISO, & OPS are some of the other data that get considered for each player.

Let’s take a look at my top pitching streamers for this week.

Top Pitching Streamers 5/2 – 5/5

Drew Rasmussen (39% Rostered) Monday @OAK  – Welcome to the center of attention Drew! After six shutout innings of two hits and a walk with nine strikeouts against the Seattle Mariners last week, you have our attention. Rasmussen had an astonishing 19 whiffs on 84 pitches (22.6% swinging-strike rate) and had a 38% or greater CSW (called strikes+whiffs) on both his cutter and slider. Rasmussen is in the top 98% in terms of fastball spin and he had all of his pitches with their spin rates working well in this start.

He looks to build upon that with his start Monday against the Athletics, who have a 74 wRC+ against RHP with a .205 batting average against and an over 26% K rate. They also have a 0.93 ISO which is the fifth-worst in baseball over the last two weeks against RHP. Start Rasmussen with confidence.

Bruce Zimmermann (9% Rostered) Tuesday vs MIN  – Easily one of the biggest surprises of the season that’s not getting talked about, Zimmermann has a .093 ERA in four starts, with 21 strikeouts in 19.1 innings pitched. With John Means going down to Tommy John surgery, Zimmermann has stepped up to be the ace of this Orioles rotation. While his expected stats show some regression coming, Zimmermann has made strides with both his changeup and slider. His changeup has gained almost an inch more of horizontal break and his slider has added nearly 2.5 more inches of drop.

Zimmermann faces the Minnesota Twins, who aren’t necessarily bad against LHP over the last few weeks but are in the middle of the pack in terms of ISO and only 17th in runs per game at just under four. I think Zimmermann can get the advantage in this matchup.

Michael Pineda (10% Rostered) Tuesday vs PIT – Pineda started the season with the Tigers a few weeks late but has looked serviceable, throwing 10 innings with four earned early on. The strikeout stuff has not been there (only two K’s in each of his first two starts), but in the right matchups, he should be able to exploit his opponent and stack up innings for your team.

Pittsburgh has the second-worst wRC+ against RHP since April 14th, with a putrid 59. They also are hitting .199 with a nearly 29% K rate. Combine that with the fact that they’re in the bottom 10 in runs per game this season and it’s a slam dunk for me with Pineda.

Nick Martinez (3% Rostered) Wednesday @CLE  – To see Nick Martinez rostered in only 3% of leagues on Fantasypros was rather shocking to me. While his ERA of 4.12 could be due for some regression, Martinez has upped his K percentage considerably this year, while lowering his O-Contact percentage to an astounding 49.2% this year (over 70% previous three seasons).

Martinez faces the Guardians who are in the middle of the pack against RHP but only batting .235 as a team. I think Martinez could be a nice streamer here.

Adrian Houser (10% Rostered) Thursday vs CIN – Adrian Houser will never be a “sexy” pick, but he’s one that can always work in a pinch. If you look at Thursday’s short slate of games, it’ll definitely be a pinch.

Houser and his 3.52 ERA will be at home against the third-lowest scoring team in baseball in the Cincinnati Reds. The Reds are batting .154 with a 28 wRC+ and an over 30% K rate over the last two weeks against RHP on the road and are always a prime streaming target to go against. All those marks are the worst in baseball. You could find a lot worse than Houser for Thursday’s games.
