The Seattle Mariners have piled up the runs at home lately, plating at least four runs in five of their last six games at T-Mobile Park.
My Royals vs. Mariners predictions expect the offense to give Seth Lugo plenty of trouble as they pull out the win.
Let’s dive deeper into my latest MLB picks for Saturday, May 2.
Who will win Royals vs Mariners today: Mariners (-140)
Although the Seattle Mariners have been inconsistent this season, their offense has been a clear strength at home, specifically against right-handed pitchers.
Seattle currently ranks second against righties in wRC+ at home, trailing only Detroit.
Kansas City Royals starter Seth Lugo will struggle to slow Seattle’s offense. He is sitting in the 18th percentile in whiff rate and is struggling to miss bats, leading to a lot of contact. Lugo also ranks in the 26th percentile in expected batting average.
The M's offense is set up for a productive outing tonight.
COVERS INTEL: The Mariners rank second in line drive rate against righties at home, hitting them 22.1% of the time.
Royals vs Mariners Over/Under pick: Over 7.5 (-110)
Lugo’s underlying profile screams regression. He owns a 3.91 xFIP, 4.31 xERA, and has allowed homers on only 2.4% of his flyballs, not even a quarter of his career rate (11.7%).
On the other side, Emerson Hancock has stranded 95.4% of opposing baserunners. That has made his ERA more flattering than it should be. For reference, his previous marks were 71.2% as a rookie and 72.2% last season.
With some red flags on both sides, this matchup sets up well for the offenses.
