Cal Raleigh Set to Rejoin Mariners Lineup in Finale vs. Royals

After a rare rest day, Cal Raleigh is expected back in the lineup Thursday night as the Seattle Mariners aim to close out their four-game series against the struggling Kansas City Royals with another win.

Get today’s top MLB predictions from elite sports analysts.

Raleigh took just his second night off this season on Wednesday, hours after being named the American League’s starting catcher for the upcoming All-Star Game. In his absence, Randy Arozarena continued his power surge, belting his fourth home run in three days to lead the Mariners to a 3-2 win.

“He’s really pushed himself. He’s learned a ton,” manager Dan Wilson said. “He’s done all the things you hope players do … and I don’t expect the second half to be any different.”

Raleigh has been dominant in 2025, leading all of baseball with 33 home runs and ranking second in RBIs with 71. He won a Platinum Glove last year, cementing his reputation as a two-way force behind the plate. Still, the national attention has made the humble slugger slightly uncomfortable.

“Sorry for all this nonsense the last couple days,” Raleigh said. “Seeing your face everywhere was a little uncomfortable.”

With the Mariners enduring a stretch of 17 games in 17 days, Wilson opted to give his catcher a breather. Seattle will also call up rookie right-hander Logan Evans (3-2, 3.38 ERA) to start Thursday. It marks his first appearance against the Royals and his eighth start of the season.

Kansas City, meanwhile, has dropped nine of its last 11 games and continues to struggle offensively. Right-hander Seth Lugo (5-5, 2.74 ERA) gets the nod for the Royals after a dominant June in which he posted a 1.26 ERA over five starts. However, Lugo has struggled in limited outings versus Seattle, owning an 11.12 ERA across two appearances.

Offensive woes have plagued the Royals, who’ve managed just 13 runs across their past nine losses. Bobby Witt Jr. and Salvador Perez remain the only consistent run producers in an otherwise cold lineup.

“There were quality at-bats there, but we didn’t square a whole bunch up,” manager Matt Quatraro said. “These guys have an elite bullpen, they have elite pitching.”

Seattle’s consistency, both on the mound and at the plate, makes them a tempting pick in today’s MLB game forecasts, especially with their star catcher back behind the dish.
