MLB Opener 4/2/17

KeyElement

Pretty much a regular
Spring Training 4-4, +4.1% RoR

4/2/17
Cubs-Cardinals, Lester (24-8) / Martinez (22-9) First 5 Innings, Under 3.5, -102

A premier match-up of two guys that posted a combined 6-2 under record last year versus the opponent in question. Both are strikeout/ground ball pitchers that seldom allow the long ball.
The Cubs (supposedly) awesome offense has swung for the fences this spring and has not focused on contact hitting. You don’t cure that overnight just because the regular season is starting. There will be a carryover effect and the fact the Cubs led both the Cactus and Grapefruit leagues in strikeouts this spring will probably show up early and often.
The weather should be cool and cloudy with a 10% chance of rain, and a Southeast crosswind from right field to left. With a lefty/righty matchup that is in Martinez favor, but Lester dominated the Cardinals last year and we should not fear anything else.
Five innings of dominance from both starters is all I can see at this point. You also have the advantage of a Cactus/Grapefruit matchup, meaning neither offense has faced this particular starter this spring.
The number in parentheses indicates the quality start record of each starter last year, based on my own calculations, which are much better than MLB’s standard 6/3 and consider every start, not just the ones fitting the MLB format (which is inaccurate, a 4.50 era is not a quality start).
The only real fear I have about unders this year is that MLB likes the results of juicing the ball instead of the hitters. After a few years of average era’s being around 4.0 in the N.L. and 4.05 to 4.10 in the A.L., they juiced her up last year and pop flies from little guys are getting out easily. If you caught the first Cubs-Astros game in Houston you may have noticed Altuve’s homer was an opposite field shot from a relatively small guy, and years ago was just a pop out to right, but when he lofted it he had no doubt it was going out. Nowadays, instead of driving the ball hitters are using an uppercut swing, because they can count on the ball to carry.
The good news regarding unders is that bettors love overs and will consistently support high numbers, even when two top guns like Lester and Martinez are matched up.

Good analysis.

Curious about this bit about the quality start. It seems you are using every start they made, so what are you using that makes them all a "quality start?" I would agree that a 4.50 ERA may not be a quality start, but if you're simply using every start they make wouldn't that be even less restrictive than what MLB uses, as opposed to more restrictive?

The exact formula is mine and will remain so, but yes, every start is considered. You either put your team in a position to win or you did not, and the length of time or number of innings may have little to do with that. Example: A guy goes 5.2 innings with a shutout, maybe even a no hitter or perfect game going. The he leaves due to injury. In the MLB formula that is not a quality start, but don't you feel it darn sure is? The MLB W/L formula is almost as ridiculous, but I won't go there today.

Of course. If you're using every start though, you aren't exactly quantifying "quality" starts.
 
Good analysis and good hit

"posted a combined 6-2 under record last year versus the opponent in question" just wondering where you have that data from
