(-110/-110)-130

Seattle Mariners – Moneyline (+110)
Out of every team in action today, the weakest outfield defense is that of the Seattle Mariners.
Explain: Defense is an integral part of preventing (or, in this case, allowing) hits and runs.
Cal Raleigh – Over/Under 1.5 Total Bases (+115/-145)
Cal Raleigh has seen a big gain in his exit velocity on flyballs this season; just compare his 97-mph average to last year’s 94.9-mph EV.
Explain: Most home runs are flyballs, and the harder those flyballs are hit, the more often they turn into home runs. This is a strong indicator of power.
Randy Arozarena – Over/Under 0.5 Total Bases (-145/+115)
Randy Arozarena hits a lot of his flyballs to center field (38.3% — 84th percentile) and is fortunate to face the league’s 10th-shallowest CF fences today.
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.

Shane Bieber – Over/Under 12.5 Pitching Outs (+110/-140)
Considering both his underlying tendencies and the matchup, Shane Bieber is projected to throw 75 pitches in today’s matchup by the leading projection system (THE BAT X) system, which is the least on the slate today.
Explain: Pitchers who throw relatively few pitches are more likely to get pulled from the game earlier, record fewer outs, and generate fewer strikeouts.
Isiah Kiner-Falefa – Over/Under 0.5 Hits (-180/+135)
Isiah Kiner-Falefa is an extreme groundball hitter and faces the strong infield defense of Seattle (#2-best of the day).
Explain: This player’s skill set matches up poorly with the opposing team’s defensive strength, which may lead to worse-than-usual performance.
Toronto Blue Jays – Moneyline (-130)
The worst projected lineup of all teams on the slate in terms of overall hitting ability is that of the the Toronto Blue Jays.
Explain: A pitcher who faces a weak opposing offense will be more likely to exceed his usual performance, particularly in terms of hits and runs, in that game.
