Cubs Rockies Matchup

We usually do these on the first game of a series.  I was going to skip this series since we don’t have enough data to properly rank players.  The lines today and yesterday are kind of interesting however which is the nexus for this post.

Here’s what the Ouija Board says about today.

DATE 04_21 8:10_PM CHN COL
LINEAWAY CHN [ 0.556 ] < 0.574 >
LINEHOME COL [ 0.488 ] < 0.444 >
CHN 9 8 COL 11 10

Both teams have approximately the same record so the DeltaWAA is  0 making this an even steven game based on win/loss records.  Darvish has a  2015-2017 career split of +4 as shown here earlier.  Here is Anderson’s career.

Year WAA Name_TeamID Pos Rank
2016 1.8 Tyler_Anderson_COL PITCH +187+
2017 -0.9 Tyler_Anderson_COL PITCH XXXXX
Total 0.9

OK.  Based on career of starters CHN has an advantage.  Here is a rundown of COL BAT based on that three year career split.

Rank WAA Name_TeamID Pos
+002+ 25.1 Nolan_Arenado_COL IF
+020+ 12.2 Charlie_Blackmon_COL OF
+039+ 10.0 Carlos_Gonzalez_COL OF
+082+ 6.6 Trevor_Story_COL IF
+188+ 3.3 DJ_LeMahieu_COL IF
+XXXXX+ 2.8 Gerardo_Parra_COL OF
+XXXXX+ 2.5 Ian_Desmond_COL IF
+XXXXX+ 2.4 Pat_Valaika_COL IF
+XXXXX+ -0.3 Ryan_McMahon_COL IF
+XXXXX+ -0.4 Mike_Tauchman_COL OF
+XXXXX+ -1.3 Tony_Wolters_COL C
+XXXXX+ -3.4 Chris_Iannetta_COL C
Total 59.5

The above is based on around opening day roster but should be close. COL has around +60 and CHN is around +50.  Both teams have around the same value relief pitching as well.

Currently the Cubs line requires the Cubs having greater than 57.4% probability of winning, COL   44.4%.   Here is the line yesterday on 4/20.

DATE 04_20 8:40_PM CHN COL
LINEAWAY CHN [ 0.535 ] < 0.512 >
LINEHOME COL [ 0.512 ] < 0.512 >
CHN 8 8 COL 11 9

This is as even steven as betting lines get.  Each team is equal with a probability of 51.2%.  We aren’t ready to look at current year data but with the three year split Hendricks (+13.1) is far superior to Gray (-1.1).  Eyeballing this Hendricks would be considered Tier 1, Gray perhaps Tier 4.  With the hitting and relief about the same CHN should have had a clear advantage yet they have that advantage today with the market instead.

The market on the opening game of this series didn’t know what was going to happen.  Hendricks pitching in the thin air of Colorado would have more issues than a normal pitcher because the balls don’t break as much.  He did get shelled for 3 runs the first inning but recovered after that.

The DeltaWAA expected probability made yesterday’s game an even steven match.  Hendricks would have moved the needle in favor of the Cubs as well as the lineup/starter/relief combos.  Would it have moved it to 58.2% in favor of the Cubs?  Can’t tell.  We can only look at career data for April games and don’t have that modeled.   Next month we’ll have better numbers to analyze.

That is all for now.  The next part to the career series coming and a multi-part series to explain OPS and why it’s such deceptive stat.  Until then….
