Colorado Rockies Insights

• Colorado Rockies – 1st Five Innings (F5) Moneyline (+140)
  Ryan Feltner was rolling in his previous GS and gave up 0 ER.
  Explain: A pitcher who was strong in his last outing may be sharp once again in his next outing.
• Willi Castro – Over/Under 0.5 Hits (-185/+145)
  Willi Castro has primarily hit in the top-half of the batting order this year (56% of the time), but he is projected to bat 7th in the batting order in this matchup.
  Explain: The lower in the order a player bats, the fewer plate appearances he will get and the fewer opportunities he will get to hit the Over for every market. A player who hits lower in the order than he normally does may provide extra value opportunity since the market may be based on him hitting higher.
• According to the leading projection system (THE BAT X), the projected offense for the Colorado Rockies today has an estimated true talent wOBA of .306, which is considerably lower than their actual wOBA of .324 this year.
  Explain: Betting lines are often based on seasonal team quality. If today’s lineup is watered down, however, there may be value if markets aren’t accounting for the lower quality of this offense.

Arizona Diamondbacks Insights

• Merrill Kelly – Over/Under 17.5 Pitching Outs (-140/+110)
  Tallying 17.1 outs per outing this year on average, Merrill Kelly falls in the 80th percentile.
  Explain: A pitcher who averages more outs per start than his Outs prop may be a good bet to go over, and visa-versa for the under.
• Ketel Marte – Over/Under 1.5 Total Bases (+105/-135)
  Ketel Marte’s average exit velocity has decreased of late; his 90-mph seasonal EV has dropped off to 83.1-mph over the past two weeks.
  Explain: Hitting the ball hard increases the chances of either a home run or the ball landing in fair territory for a hit before a fielder can get to it.
• Arizona Diamondbacks bats as a unit grade out 25th- in MLB for power this year when judging by their 7.2% Barrel%.
  Explain: Barrel% measures how often a player hits the ball at the optimal exit velocity and launch angle and is a terrific measure of underlying power.
