2019 Regression Risk: Why Fantasy Owners Shouldn’t Buy Into Trevor Williams’s 2nd Half “Breakout”

by Eric Stashin (aka The Rotoprofessor)

It seemed like a breakout season for the Pirates’ Trevor Williams, as he was especially good in the second half (1.38 ERA, 1.07 WHIP).  Just how real is the performance, or should it be chalked up to an aberration and be ignored?  First let’s take a look at the overall line:

170.2 IP
14 Wins
3.11 ERA
1.18 WHIP
126 Strikeouts (6.64 K/9)
55 Walks (2.90 BB/9)
40.8% Groundball Rate
.261 BABIP

His first half ERA of 4.36 alone would be a red flag, but as we start digging into the numbers it becomes clearer and clearer.  Just consider that he benefited from a 90.8% strand rate after the All-Star Break, and while he did do a good job of limiting the hard contact all season long (29.3%) his BABIP also seems unsustainable: Read more

Buy ‘Em or Deny ‘Em: Could Teoscar Hernandez Develop Into A Viable Option Or Is He One To Ignore?

by Eric Stashin (aka The Rotoprofessor)

Teoscar Hernandez has taunted us with his talent in the past, but he never had the true opportunity to fully show it in the Majors.  That finally came with the Blue Jays in ’18, and he again showed signs of being a viable option (though there wasn’t across the board success):

476 At Bats
.239 Batting Average (114 Hits)
22 Home Runs
57 RBI
67 Runs
5 Stolen Bases
.302 On Base Percentage
.468 Slugging Percentage
.313 Batting Average on Balls in Play

While he did hit the ball hard (37.3% Hard%) and showed off some power, his average/plate discipline bring significant questions.  While he wasn’t chasing outside of the strike zone (32.2% O-Swing%), his ability to make consistent contact just wasn’t there. Read more

2019 Bust Alert: Will Dereck Rodriguez Build On His 2018 Success… Don’t Be So Sure

by Eric Stashin (aka The Rotoprofessor)

Entering the season with playoff aspirations, 2018 was a huge disappointment for the San Francisco Giants.  It has led to changes at the top, and there certainly will be a trickle down effect to the talent on the field.  One of the few things we know, though, is that many will view Dereck Rodriguez (the son of Hall of Famer Ivan Rodriguez) as a key piece to the team’s future.  That makes sense, given these numbers as a rookie:

118.1 IP
6 Wins
2.81 ERA
1.13 WHIP
89 Strikeouts (6.77 K/9)
36 Walks (2.74 BB/9)
39.5% Groundball Rate
.257 BABIP

Something we’ve all learned is that sometimes numbers can be deceiving, and while it was a strong year on the surface when you start peeling back the layers the concerns mount quickly.  While that doesn’t necessarily mean he’ll fall off a cliff, that’s a scenario that we can’t rule out so easily.

2018 Leaders Review: Top 10 September SwStr%: Regression Risks Emerge (Javier Baez, David Dahl & More)

by Eric Stashin (aka The Rotoprofessor)

We often say that September results are not indicative of what the future holds, considering that September callups help to skew the competition level.  At the same time we’ve seen it before where a late season flourish helps to point towards future success.  With that in mind, let’s take a look at the Top 10 swinging strike rates among hitters over the final month of the season to see if there are any concerns arising (especially since the pitching may not necessarily be up to typical standards):

Ranking
Name
Team
SwStr%
1. Daniel PalkaChicago White Sox19.7%
2. Javier BaezChicago Cubs19.2%
3.Randal GrichukToronto Blue Jays18.1%
4.Adalberto MondesiKansas City Royals18.0%
5.Khris DavisOakland A's17.9%

7.David DahlColorado Rockies16.9%
8.Scott ScheblerCincinnati Reds16.7%
9t.Stephen PiscottyOakland A's16.3%

There are a lot of interesting names on these rankings, but let’s take a look at three of the most interesting ones: Read more

2019 Projection: Will Rhys Hoskins Rebound From His Perceived “Disappointing” 2018?

by Eric Stashin (aka The Rotoprofessor)

After a monster 2017 debut (.259 with 18 HR and 48 RBI over 50 games) fantasy owners had high expectations for Rhys Hoskins’ 2018 campaign.  While he wasn’t completely useless, it’s easy to dub him as a disappointment as he fell well short of expectations.  Just how far short?  Let’s look at the numbers:

558 At Bats
.246 Batting Average (137 Hits)
34 Home Runs
96 RBI
89 Runs
5 Stolen Bases
.354 On Base Percentage
.496 Slugging Percentage
.272 Batting Average on Balls in Play

It wasn’t a poor approach that had a negative influence.  In fact for a power hitter his underlying numbers are impressive, with a 7.9% SwStr% and 22.8% O-Swing%, and you can argue that he has more upside than his 22.7% strikeout rate and 13.2% walk rate.  So what caused the “disappointing” campaign?  There are two key numbers: Read more
