Pitching Streamers to Target in Week 9 of Fantasy Baseball

While pitchers continue to go down with injuries as the season continues, some returns are imminent. Grayson Rodriguez, Garrett Whitlock, and others could be back by the time you read this article. Others like Jose Urquidy and Kris Bubic could be back by the end of the month. This means that fantasy managers likely will have to continue to rely on pitching streamers to earn wins.

Here are a few of my favorites for the week ahead.

Pitching Streamers Available in Some Leagues (30-50% Rostered)

Brayan Bello (SP – BOS)

Next Start: Wednesday 5/22 at TB

Bryan Bello made his return to Boston’s rotation against the Nationals after nearly a month on the shelf. He allowed two earned runs, and only struck out one, but picked up the win.

Bello’s next start is against Tampa, a team that ranks among the 10 worst in run differential and in team batting strikeouts. Bello does not strike out a ton of batters, 7.6 per nine innings, but this presents him with a chance to pick up a fair amount of Ks. Tampa has the eighth most strikeouts against right handed pitching.

Bello relies on his slider and changeup to get batters out. Both pitches have whiff rates above 30% and putaway rates of 19%. Here is a look at his changeups from earlier in the season:

Tampa’s offense does well at picking up walks against righties, but they will be hard-pressed to do so against Bello, who has allowed 2.5 walks per nine innings this season. Even if Tampa’s batters do get on base, Bello has done well at limiting opposing teams’ baserunners. He has a 78% left-on-base rate, and a 55% groundball rate. Tampa has the ninth-highest groundball rate in baseball.

This matchup plays into Bello’s strengths and Tampa’s weaknesses, making him an excellent pitching streamer for the week ahead.

Luis Gil (SP – NYY)

Next Start: Thursday 5/24 vs SEA

Luis Gil continues to dominate, picking up wins in his last three contests, which came against Baltimore, Houston, and Tampa. Gil earned quality starts in each game, allowing one run across 18.1 IP, while striking out 13. He walked seven batters, which has been a problem his entire career, including his time in the minors.

Gil has incredible strikeout upside, finishing below 10 K/9 in just one 13-inning stint at the High-A level of the minors. The biggest risk for Gil is that he has finished one stint in the majors or minors with a BB/9 rate under four. His high walk rate likely will keep him a streamer until he shows he can consistently limit walks.

Fortunately, for Gil, the Mariners struggle against righty pitchers in particular. They have the fifth-worst batting average and the most strikeouts against RHP. Seattle also possesses the highest strikeout rate in baseball overall.

Gil has some filthy pitches in his arsenal that have resulted in his 2.51 ERA and 80% LOB rate. His fastball, changeup, and slider have batting averages against of .155 or lower. They have 29%, 26%, and 30% whiff rates respectively, as well as 22%, 22%, and 19% putaway rates respectively. Here is a great look at his slider, arguably his best pitch:

If he can get the walks under control, he would be a top starter. But because of that risk, he remains one of the best pitching streamers available.

Dean Kremer (SP – BAL)

Next Start: Friday 5/24 at CWS

Dean Kremer may have lost in his last matchup against the Diamondbacks, but he tallied 10 strikeouts in 5.2 innings. Kremer’s next start, as of writing, comes against the White Sox, one of the worst teams in baseball.

That 10-strikeout outing ticked Kremer’s K/9 rate up to 9.2. Over 46 innings this season, he has a sub-3 BB/9 rate, a 64% LOB rate, and a 42% GB rate. Kremer has also allowed a super-low .200 BABIP, but that is legitimized with a 13% LD rate. Even if that regresses, he should experience some positive regression to his home run rate, since his HR/FB rate is 16%.

Kremer has multiple ways to get batters out, which has led to his improvements this season. Though his sinker has just a 9% whiff rate, it has a 39% putaway rate. His four other pitches range between 24%-37% whiff rates, even his fastball:

Kremer cut out his sweeper from last season and swapped his changeup for a splitter. That splitter has a -1 degree launch angle, a clear reason why his groundball rate has improved. And Chicago has the 10th highest GB% in baseball.

This is a great matchup for Kremer, as the White Sox have the third worst AVG and the fifth fewest walks against RHP this season.

If Kremer is available in your league, you should make him one of your top pitching streamers for the week ahead.

Widely Available Pitching Streamers (0%-30% Rostered)

Sean Manaea (SP – NYM)

Next Start: Sunday 5/19 at MIA

Sean Manaea picked up back-to-back quality starts against Philly and St. Louis in his last starts. Those starts improved his ERA to 3.05 on the season.

Manaea goes into this start with his worst K/9 rate (7.9) since 2020, and the worst BB/9 (4.8) and GB rates (32%) of his career. His game against the Marlins is a chance for Manaea to experience some positive regression to those numbers. Miami has the third most strikeouts against lefty pitchers, and Manaea has some filthy stuff, despite the lack of strikeouts.

Manaea’s sweeper has a 40% whiff rate and a 21% putaway rate. His slider has a 37% whiff rate and a 50% putaway rate. And his changeup and fastball have 29% and 27% whiff rates respectively. Here is a look at Manaea getting outs with his fastball and slider:

Another thing working in Manaea’s favor and against the Marlins is Miami’s league-high 51% GB rate. The Marlins also have the fifth-worst batting average against LHP.

This is a great game for Manaea and makes him an excellent choice as one of the best pitching streamers for the week ahead.

Reese Olson (SP – DET)

Next Start: Monday 5/2o at KC

Since the start of May, Reese Olson has allowed just one run across 19 IP. He has a 15:4 K:BB ratio during that span, and has improved his ERA to 2.09.

Olson has a 7.8 K/9 rate this season, which is about a half strikeout per nine innings less than his career average. That may not improve against the Royals, who do not strike out very much at all. Despite that, this matchup remains an advantageous one for Olson.

He has improved his BB/9 and LOB% to career bests. He also possesses a career-best 55% GB rate, the seventh-highest in baseball among qualified starters. That should help him immensely against a team that has avoided hitting groundballs.

Olson also has the stuff to pick up strikeouts, even against a tough opponent. His slider and changeup in particular have been superb out pitches for him this season. They have BAAs against of under .150. His slider has 41% and 23% whiff rates, and his changeup has a 48% whiff rate. Take a look at his slider here:

He may not strike out every batter, but he has a chance to continue his excellent stretch of starts. Make him one of your top pitching streamers for the week ahead.

Cal Quantrill (SP – COL)

Next Start: Tuesday 5/21 at OAK

Cal Quantrill looked great in recent games, winning his last three, all of which were quality starts as well. He also has quality starts in six of his last seven games.

Quantrill has just a 6.2 K/9 rate, but has managed well. He has not allowed many baserunners to score, with an 80% LOB rate. His career best 50% GB rate certainly has to do with that. He has achieved such a high GB% thanks in large part to a nasty splitter. It arguably is his best pitch, with a .153 BAA, a 24% whiff rate, and a 19% putaway rate, and has induced a -1 degree LA. Here is a look at it in action:

Oakland could not be a better opponent for Quantrill, as a pitcher who does not strike out many batters. They have the fifth worst K% in baseball and the sixth most strikeouts against RHP. Oakland is also tied for the fifth worst AVG against RHP.

Even though Colorado as a team is struggling, you can trust Quantrill in this matchup as one of your top pitching streamers for the week ahead.
