Waiver Wire Guidelines: How Should Fantasy Owners Value Tyler Mahle & Andrew Triggs?

by Eric Stashin (aka The Rotoprofessor)

If you thought we had small sample sizes for the hitters around the league, for the majority of pitchers we have just a handful of innings (one start) to try and make determinations off of.  It’s nearly impossible, though looking at pitch usage and velocity (among other things) can give us a little bit of insight.  Let’s take a look at two starters who thrived in their first starts and try to determine if they can maintain the performance moving forward:

 

Tyler Mahle – Cincinnati Reds
6.0 IP, 0 R, 1 H, 2 BB, 7 K (vs. Cubs)

Is one start enough to change our opinion of Mahle?  Here’s what we had written about him in our 2018 Fantasy Baseball Draft Guide:

Mahle struggled with his control in his 4 starts in the Majors (11 BB), though coming up through the minors that has been his biggest strength (1.9 BB/9).  Is that enough of a skill to bring success?  Between Double and Triple-A last season he posted a 10.5% SwStr% (9.5% at Triple-A, leading to a 7.74 K/9) and a 40.1% groundball rate (which will mean potential home run issues in the Majors).  Given the questions in the rotation he’ll get another shot, but the upside is minimal.

While Mahle did have a 10.5% SwStr% in his first start, it’s not enough to convince us of his ability to maintain a strikeout per inning.  That’s especially true when coupled with his inability to get opponents to chase (23.9% O-Swing%) and his 12.00% Whiff% on his fourseam fastball (he’s not overpowering, as Rich Wilson of Prospect 361 described it as a “modest fastball” prior to the season).

Mahle also continued to struggle generating groundballs, with a 36.4% groundball rate, and that will eventually catch up with him.  Could he have some value, especially in the WHIP department?  Absolutely, but don’t look towards him as a potential fantasy ace and there could be more bad days than good if he’s not generating many strikeouts.

Waiver Wire Guidelines:

  • 10 Team Leagues – Don’t Add
  • 12 Team Leagues – Streaming Option, At Best
  • 14+ Team Leagues – Worth Gamble
  • NL-Only Leagues – Worth Gamble
  • Keeper Leagues – Worth Gamble

 

Andrew Triggs – Oakland A’s
5.0 IP, 1 R, 4 H, 2 BB, 7 K (vs. Rangers)

Injuries cost Triggs the bulk of ’17 (65.1 IP), and that likely caused him to be a bit overlooked.  However now over 126.2 IP in the Majors he’s shown signs of all three skills we look for from a pitcher:

  • Strikeouts – 7.96 K/9
  • Control – 2.42 BB/9
  • Groundballs – 49.9%

He owns a career 10.5% SwStr% and while some define his pitches differently, he’s shown a willingness to use his curveball (as per Brooks Baseball) more and more:

  • 2016 – 18.51%
  • 2017 – 23.10%
  • 2018 – 37.50%

That was his big strikeout pitch in his first start (24.24% Whiff%) and over the course of his career opponents have hit .180 against it with a .274 SLG.  It was one start, but it makes sense to continue focusing on the pitch.  He’s not a hard thrower, but it’s possible he continues with a K/9 in the 8.00-8.25 range.  When coupled with the other numbers that makes him an extremely intriguing option as long as he’s healthy.

Waiver Wire Guidelines:

  • 10 Team Leagues – Monitor
  • 12 Team Leagues – Worth Adding
  • 14+ Team Leagues – Must Add
  • AL-Only Leagues – Must Add
  • Keeper Leagues – Worth Adding

    Waiting for Realmuto to come back from DL around 4-19, right now using Avila as my C; is it worth it to add Ianetta or James McCann in a fee league or are all three close enough that it’s not worth it.

    thank you

    • Rotoprofessor says:

      The frustrating part about AVila is the playing time and lack of certainty. I could see adding Ianetta I guess, but chances are it’s not going to make a big difference.

      • LanceCT says:

        I want to jump on it but I kind of think the same thing, in the end assuming Realmuto comes back, there won’t be much of a difference.

        Thanks for the sounding board, I truly appreciate it, you’re the best!

    What kind of upside do you think Triggs has? I just picked up Lopez on your advise yesterday. Since I’m just filling bench spots I’m really just swinging for the fences hoping someone breaks out as a top 30 SP.

    • Rotoprofessor says:

      If you are just swinging for the fences for the highest upside arm it’s going to be Lopez. He definitely has the bigger potential, but also the bigger risk

    Hey,

    Do you think Lucchesi is worth picking up? I actually watched some of the last game and was impressed at how he looked. He is a bit lanly and has a deceptive looking delivery, most likely his next start is one to avoid playing at Coors field, but moving forward what do you think about him?
