Starting Pitcher Chart – September 17th, 2021

With the season winding down, I wanted to find something that would be useful for those still contending in their leagues. I decided to do something that isn’t particularly new, but we don’t have it here at the site: a starting pitcher chart for the day’s slate of games. I’ll include their performance over the last five starts, their opponent’s wOBA versus the pitcher’s handedness, and then my start/sit recommendation for 10-team, 12-team, and 15-team (or more) leagues.

Let me know what y’all think about this. Obviously these are general recommendations and your league situation will carry more weight whether you are protecting ratios or chasing counting numbers. This is for standard 5×5 roto leagues. The thresholds for H2H starts are generally lower, especially in points leagues so I thought there would be more value focusing on roto. For the weekend, Justin & I will use the Friday podcast to discuss the relevant weekend streamers. By popular demand, these will start coming out the day before the slate in question.

German Marquez will start Friday after the weather ppd. for Colorado on Thursday. I’d start him across the board.

September 17th Starter Chart

Zack Wheeler PHI at NYM x x x 4.32 ERA, 1.18 WHIP, 22% K-BB .337 – 3rd Not worried about elevated ERA in L5
Logan Webb SFG ATL x x x 2.45 ERA, 1.03 WHIP, 22% K-BB .312 – 16th Putting finishing touches on a brilliant season
Luis Castillo CIN LAD x x x 3.06 ERA, 1.15 WHIP, 20% K-BB .294 – 24th Not the best matchup, but I can’t see sitting him
Chris Sale BOS BAL x x x 2.52 ERA, 1.40 WHIP, 22% K-BB .314 – 14th Ugly WHIP isn’t a deterrent
Hyun Jin Ryu 류현진 TOR MIN x x x 6.20 ERA, 1.32 WHIP, 19% K-BB .276 – 29th Struggling w/2 7 ER stinkers in L5, but I’m still starting
Chris Flexen 플렉센 SEA at KCR x x x 3.56 ERA, 1.20 WHIP, 11% K-BB .308 – 20th Quietly enjoying a very solid season
Dylan Cease CWS at TEX x x x 5.06 ERA, 1.34 WHIP, 19% K-BB .322 – 11th Last start really pushing the ERA, 3.00 in other 4
Adrian Houser MIL CHC x x x 1.82 ERA, 0.96 WHIP, 6% K-BB .320 – 13th Only 6 ER in his last 7 outings (37 IP)
Cole Irvin OAK at LAA x x 7.04 ERA, 1.91 WHIP, 4% K-BB .293 – 26th Still worth throwing in favorable matchups like this
Taylor Hearn TEX CWS x x 3.94 ERA, 1.03 WHIP, 15% K-BB .352 – 8th Tough matchup, but streamers are inherently risky
Taijuan Walker NYM PHI x x 5.59 ERA, 1.07 WHIP, 17% K-BB .329 – 5th Has gone 6+ IP in 5 of last 6
Zach Plesac CLE at NYY x x 3.81 ERA, 1.35 WHIP, 9% K-BB .324 – 8th Underwhelmed this yr, but usable streamer
Brady Singer KCR SEA x x 3.07 ERA, 1.34 WHIP, 15% K-BB .293 – 25th L7 ER shows volatility: 7, 5, 2, 1, 1, 0, 6
Luis Patiño TBR DET x x 4.57 ERA, 1.65 WHIP, 7% K-BB .310 – 17th Inconsistent IP totals make him a complete wildcard
Elieser Hernandez MIA PIT x x 4.74 ERA, 1.32 WHIP, 17% K-BB .290 – 27th AVG’ing <5 IP in L5 w/a 2.2 HR9; matchup is the only positive
Ian Anderson ATL at SFG x 4.71 ERA, 1.95 WHIP, 1% K-BB .330 – 4th Don’t be afraid to play it safe here & pass
Miles Mikolas STL SDP x 6.04 ERA, 1.49 WHIP, 8% K-BB .269 – 30th Matchup & desperation would be the only reasons to stream
Michael Pineda MIN at TOR 3.92 ERA, 1.34 WHIP, 15% K-BB .355 – 1st Never TOR is a standing rule in streaming for me
Josiah Gray WAS COL 7.88 ERA, 1.71 WHIP, 6% K-BB .315 – 15th Just too many HR to trust this late in the season
Wil Crowe PIT at MIA 8.71 ERA, 1.93 WHIP, 10% K-BB .273 – 29th Matchup not enough to lure me in here
Casey Mize DET at TBR 3.60 ERA, 1.15 WHIP, 7% K-BB .308 – 19th Back on the managed IP plan probably rest of the way
Corey Kluber NYY CLE 7.98 ERA, 1.83 WHIP, 17% K-BB .297 – 23rd Not nearly enough upside to risk this
Madison Bumgarner ARI at HOU 5.81 ERA, 1.39 WHIP, 7% K-BB .372 – 4th 5 ER in each of the last 3 outings
Keegan Akin BAL at BOS 4.00 ERA, 1.04 WHIP, 9% K-BB .298 – 22nd Your ratios will likely be Akin if you take this gamble
Vince Velasquez SDP at STL 12.23 ERA, 2.27 WHIP, 2% K-BB .309 – 18th He’s a Padre now?!?! Still unusable
Zach Davies CHC at MIL 7.71 ERA, 1.62 WHIP, 11% K-BB .320 – 14th No
Kyle Freeland COL at WAS 5.92 ERA, 1.41 WHIP, 16% K-BB .383 – 1st No Ks, brutal matchup, hard pass
*road vR for COL

It might be splitting hairs, but I’m wondering why Freeland is the worst starter on the board for tomorrow. If you said: because he’s still not over his hip injury, I could understand that.

Is this a brutal matchup because the Nats have scored a lot of runs in the last month or so? Or because he doesn’t matchup well with their lineup? Is it because the Nats have the fewest K’s in the league on offense?

Is he really a worse start than Davies, Velazquez or Kluber?
OK, maybe I am splitting hairs.

Well, it’s not like I have a choice with my dinosaur Roto rules anyway. I’ll have to hope it’s another mediocre-poor start, like the last one in Philly, rather than a disaster, like the one in Coors against the Giants.

Nats have murdered lefties this season – first in team wOBA vs. LHP at .350, even better over the last 30 days (as shown in the next-to-last column).

But anyway, Marquez moves back to Friday because of Thursday’s rainout, Freeland to Saturday.

OK, you guys are right. He faces bad matchups his last two starts if he stays in rotation: Giants at Coors and Nats at Coors. There is a possible way I can ditch him; let’s see what happens.

Looks like you were right about the Nats lineup. They beat up on Marquez. But I got out from under Freeland by a weekly waiver claim (every Friday night at 11 pm) of Richard Bleier, and waived Freeland goodbye.

So now he’ll throw a gem on Saturday because…well…(expletive deleted) me, that’s why.

Bleier won’t do much, but he might help my WHIP a little, or at least he won’t kill it, which I couldn’t count on from Freeland. And he might even get me a hold or two. That’s good enough, for the moment.

Just say “No” to Zach Davies. 🙂

Kyle Freeland.
The recommendation was made.
The recommendation was practical, reasonable, sensible.
I took action on it, agreeing with the thinking.
Six shutout innings and a win with 7 K. (8 runners isn’t ideal, but it might have been much worse).

Because…this is fantasy baseball, not Newtonian mechanics.
