D-Backs host Astros, shoot for fifth straight win

Baseball Betting Lines

09/04/2010 - (Sportsbook Betting Lines) - Recent trade acquisition Joe Saunders tries to make it two wins in a row for the first time since arriving in Arizona tonight, when the Diamondbacks meet the Houston Astros in the middle matchup of a three-game weekend series at Chase Field.

The red-hot hosts won Friday's opener, 4-3, on Augie Ojeda's sacrifice fly in the bottom of the eighth inning. Adam LaRoche went 2-for-4 with two runs batted in and Gerardo Parra added two hits and a run scored for the Diamondbacks, who have won four in a row and seven of eight while outscoring their opponents by a 58-28 margin.

Aaron Heilman (5-5) earned the win with a scoreless top of the eighth and Juan Gutierrez worked a scoreless ninth to preserve the victory and earn his seventh save.

Wilton Lopez (5-1) suffered the loss after yielding the deciding run on one hit over one inning of work for the Astros, who had a three-game win streak snuffed out.

Saunders, a 29-year-old Virginia native, has won just two of seven starts since the late-July transaction that brought him to the National League from the Los Angeles Angels of Anaheim in exchange for right-hander Dan Haren.

The left-hander allowed just three runs in 16 innings over his initial two NL outings, but then lost four in a row while surrendering 23 runs in his next 22 innings pitched. He bounced back for a win in his most recent effort, allowing two runs on 10 hits across eight innings in Arizona's 7-2 home triumph over San Diego on Monday.

Saunders has never faced the Astros.

Right-hander Bud Norris tries to restart a win streak for Houston when he opposes Saunders tonight. The 25-year-old, who won six games in 11 appearances as a rookie last season, was 2-7 this season before a seven-start unbeaten streak that saw him record four straight wins.

That run ended in his last performance, however, when Norris was touched for five runs on eight hits in a 5-1 loss to the New York Mets last Sunday in Queens.

Prior to that game, the Astros had won six straight Norris starts as he dropped his earned run average more than a run from 6.09 to 5.03.

The former sixth-round draft pick (2006) has lost his two career starts against the Diamondbacks, while giving up 12 runs in 11 hits in just six innings.

Arizona has now won four of five meetings with the Astros this season following Friday's result.

Who Makes the Sportsbook Betting Lines?

Las Vegas Sports Consultants (LVSC) is the world’s premier oddsmaking company and the most respected authority on making the lines. Mike Seba is a Senior Oddsmaker at LVSC and has been making lines for the last six years. In our extended interview, Seba explained that there are 4-5 oddsmakers assigned to make lines for each of the major sports (pro & college football and basketball; MLB, NHL, boxing, golf). Each of these oddsmakers bring unique opinions, strengths and weaknesses to the process. Oddsmakers at LVSC are professional sports junkies who love what they do and would probably do it for nothing if you asked them, but they do get paid for it. By necessity their approach is very research-oriented and concise, since with millions of dollars at risk there is little margin for error.

“You either have a passion for it or you don’t,” Seba said.

“The #1 thing for us is to make a line for each game that creates good two-way action. We do this by drawing from past experiences and applying them to current situations. People think it’s much more complicated, but it’s not. “

What are the Football Betting Lines Trying to Accomplish?

There is a common misconception that point spreads represent the oddsmakers’ prediction of how many points the favorite will win by. That is not the case at all – their intent is NOT to evenly split the ATS result between the teams; rather, their goal is to attract equal betting action on both sides. Stated another way, they want to create a line that half the people find appealing to bet one way while the other half find it appealing to bet the other way (known as ‘dividing the action’).

Divided action means the sportsbook is guaranteed a profit on the game because of the fee charged to the bettor (called juice or vig – typically $11 bet to win $10).

How the Opening Line Is Made

The opening line is the first line created by the oddsmakers, which is then sent out to sportsbooks. Of course there is an entire method to the madness on how the opening line is created. Seba explained that it all starts with each oddsmaker creating a line on each game based upon their own personal approach. This usually includes having up-to-date power ratings on each team.

Power ratings are the oddsmaker’s value of each team and are used as a guide to calculate a "preliminary" pointspread on an upcoming game. The power ratings are adjusted after each game a team plays. Examples of non-game factors that would require an adjustment to a team's power rating are key player injuries and player trades.

Once a game’s power rating based pointspread is determined, the oddsmaker will make adjustments to that line after considering each team's most recent games played and previous games played against that opponent. Also, adjustments are made after reading each team’s local newspapers to get a sense of what the coaches & players are thinking going into the game.

Since the oddsmaker’s ultimate goal is equally dividing the sports betting action, public perception and sportsbook betting patterns must be taken into account. For example, the public might have heavy betting interest week after week on a popular college football betting team such as USC. If an oddsmaker comes up with a preliminary line of USC -7, then an adjustment up to -7.5 or -8 would be made in response to the public’s expected USC bias.

The last step in the line-making process for each oddsmaker is taking one final look to determine whether or not the line "feels right." This is where common sense and past experience with how games are bet enters into the picture.

A round-table discussion among the 4-5 oddsmakers involved in making the line for each sport is then conducted and a consensus line is decided upon by the Odds Director before it is released to the sportsbooks. Of the 4-5 oddsmakers, generally the 2 most respected opinions are weighed more heavily by the Odds Director before he decides on the final line.

Why Sports Betting Lines Change

Once the opening line is released by LVSC, the individual sportsbooks decide if they want to make any adjustments before offering it to the public. Reasons for such adjustments include:

Experts working for the individual books having a strong opinion on the game

Individual books having players who consistently bet with certain tendencies (such as an extreme bias toward favorites or toward a certain popular team like USC)

The purpose of these adjustments, like all line adjustments, is to more equally divide the betting action.

Once betting begins, sportsbooks can adjust the line at any time. In doing so they attempt to make more attractive the team that is getting less action. By moving the line, sportsbooks can influence how the public bets on a particular game.

For example, if the pointspread on a game is 7 and most of the money is coming in on the underdog (taking the +7), sportsbooks will then move the number down to 6 ½ to try and attract money on the favorite.

Moving the line is the oddsmaker's effort to balance betting action, and often times such moves can have a major impact on a bettor’s decision. Oddsmakers can also change the line depending on various event-related factors such as player injuries or weather. Obviously, if the line comes out a week ahead of the event (which is the case in football), there is much that could happen during the week leading up to the event that could affect the line. Oddsmakers have to determine if any changes are necessary and send out an "adjusted line."

“The main objective is that our clients get equal action on both sides,” Seba said. “We’re not trying to pick the team that covers the spread, we’re trying to make it a coin flip, a tough decision (for the bettor). If we’ve done that, we’ve done our job.”

Chiefs' Treen Green out for Sunday's game

How long Trent Green will remain sidelined is unknown. Coach Herm Edwards said Monday he will miss a second straight start Sunday when the Chiefs host the San Francisco 49ers.

A two-time Pro Bowler, Green was going into a feet-first hook slide when he was knocked unconscious by a thunderous, head-snapping hit from Cincinnati's Robert Geathers.

Oddsmakers at online sportsbook MySportsbook.com currently have the Chiefs listed as 7-point favorites versus the 49ers.

The 49ers got beat by Philadelphia 38-24 as a 6.5-point underdog last week. The combined score went OVER the posted over/under total (42.5).

Alex Smith completed 27-of-46 passes for 293 yards with a touchdown. Michael Robinson rushed for 29 yards and a pair of touchdowns on five carries.

The Chiefs lost 9-6 to Denver last week as an 11-point underdog. The combined score was well UNDER the posted over/under total (38).

Larry Johnson
rushed for 126 yards on 27 carries. Damon Huard completed 17-of-23 passes for 133 yards with no touchdowns and no interceptions.
