The Kansas City Royals have played in many high-scoring games at home, with 10 of the past 14 at Kauffman Stadium going Over the total.
My Red Sox vs. Royals predictions expect plenty of fireworks again tonight.
Let's dive deeper into my MLB picks for May 18.
Who will win Red Sox vs Royals today: Kansas City Royals (-105)
Seth Lugo has made four starts against teams in the bottom half of the league in OBP. He pitched 6+ innings in each, allowing two runs or fewer in three of four.
The Boston Red Sox rank 24th in OBP against right-handed pitching and 28th in the past month. They shouldn't be too much of a challenge for Lugo, and he has a rested bullpen behind him.
Sonny Gray will have a more difficult time slowing down the Kansas City Royals. Their offense is electric at home — especially the likes of Bobby Witt Jr. and Maikel Garcia — ranking third in OBP and second in wOBA vs. righties.
COVERS INTEL: Lugo has allowed just 0.17 homers per nine innings, the lowest mark of any non-opener projected to start today.
Red Sox vs Royals Over/Under pick: Over 9 (-105)
The Royals are a very powerful offense at home, trailing only the Yankees in OPS vs. righties while ranking first in both hard hit rate and FB%.
They are making hard contact consistently and putting the ball in the air more than anybody. That's a huge plus when playing in a hitter-friendly ballpark, especially on a hot day with up to 20 mph winds blowing out. The ball will carry.
While Lugo has performed well against struggling offenses, he has had a tougher time against left-handed hitters, and the Red Sox have plenty to throw at him.
