In-depth Player Analysis for White Sox vs Mariners - Wednesday May 20, 2026

+120O/U: 7.5
(+100/-120)-140

Sean Burke – Over/Under 5.5 Strikeouts (+115/-145)
Sean Burke’s four-seam fastball rate has dropped by 5.6% from last year to this one (43.1% to 37.5%) .
Explain: Fastballs are the one easiest pitches to hit and generate few strikeouts, so a pitcher who begins to use his fastball lessoften will likely be more effective than he used to be.
Luisangel Acuna – Over/Under 0.5 Total Bases (-125/-105)
The leading projection system (THE BAT X) estimates Luisangel Acuna’s true offensive talent to be a .280, suggesting that he has had some very poor luck this year given the .086 disparity between that figure and his actual .194 wOBA.
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.
Colson Montgomery – Over/Under 0.5 Total Bases (-155/+120)
Colson Montgomery pulls a lot of his flyballs (40.2% — 98th percentile) and sets up very well considering he’ll be hitting them towards MLB’s 4th-shallowest RF fences in today’s matchup.
Explain: This player’s skill set matches up particularly well with the park he’s in today, which may lead to better-than-usual performance.

Seattle Mariners – Moneyline (-140)
The Seattle Mariners outfield defense profiles as the worst among all the teams on the slate today.
Explain: Defense is an integral part of preventing (or, in this case, allowing) hits and runs.
Luke Raley – Over/Under 0.5 Hits (-130/+100)
Luke Raley has primarily hit in the back-half of the lineup this season (80% of the time), but he is penciled in 5th on the lineup card in this 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.
It may be smart to expect positive regression for the Seattle Mariners offense the rest of the season, given that the leading projection system (THE BAT X) believes they are the 8th-unluckiest offense in baseball this year.
Explain: When teams underperform their projected talent level, markets may undervalue them even while they are likely to perform better in the near future.
