Player Prop Odds for Mariners vs Rockies - Sunday September 20, 2026

-160O/U: 10.5
(-120/+100)+135

Kade Anderson – Over/Under 4.5 Strikeouts (-115/-115)
The Colorado Rockies have 7 batters in the projected batting order that will hold the platoon advantage against Kade Anderson today.
Explain: Right-handed pitchers perform worse against left-handed hitters (and visa-versa). If several hitters hold this advantage against the pitcher, it can have a huge impact on whether he will perform well or struggle on any given day.
Julio Rodriguez – Over/Under 1.5 Total Bases (-135/+105)
Despite posting a .302 wOBA this year, the leading projection system (THE BAT X) believes Julio Rodriguez has had bad variance on his side given the .044 discrepancy between that mark and his estimated true talent wOBA of .346.
Explain: Players that are underperforming should be expected to play worse going forward, which can create value on prop Overs if the lines are too heavily weighing the unlucky, to-date underperformance.
According to the leading projection system (THE BAT X), the Seattle Mariners are expected to tally the most runs (6.6 on average) of all teams on the slate today.
Explain: THE BAT X is a highly sophisticated projection system that accounts for a multitude of factors like player quality, ballpark, weather, umpire, defense, and more.

Tomoyuki Sugano – Over/Under 3.5 Strikeouts (+100/-130)
Tomoyuki Sugano’s 2414-rpm fastball spin rate this year is in the 81st percentile among all starting pitchers.
Explain: Spin rate is a key component to fastball success in generating strikeouts and preventing runs.
Connor Norby – Over/Under 0.5 Hits (-230/+175)
Connor Norby has primarily hit in the back-half of the batting order this season (63% of the time), but he is projected to bat 2nd in the batting order in today’s game.
Explain: The higher in the order a player bats, the more plate appearances he will get and the more opportunities he will get to hit the Over for every market. A player who hits higher in the order than he normally does may provide extra value opportunity since the market may be based on him hitting lower.
According to the leading projection system (THE BAT X), the projected offense for the Colorado Rockies today owns an estimated true talent wOBA of .302, which is a good deal worse than their actual wOBA of .322 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.
