Seattle Mariners outfield prospect Jonatan Clase has been optioned to Triple-A Tacoma on Monday. The 21-year-old struggled during his brief stint with the team. He slashed .222/.250/.259 with zero home runs and three RBI in 28 plate appearances. Clase has plenty of potential and should get another shot later in the summer. In the meantime, outfielder Sam Haggerty has been recalled to take the spot on the active roster. He was hitting well in the minors, but is unlikely to do enough to carry viable fantasy value.

Los Angeles Angels outfielder Aaron Hicks has been designated for assignment by the organization on Monday. The veteran outfielder struggled during his brief time with the organization. Hicks slashed .140/.222/.193 over 18 games with the Halos. He put together a solid stint with the Baltimore Orioles last season. Sadly, Hicks couldn't translate that success over to his new team. Hicks will either decide to take the option to Triple-A or elect free agency. In a corresponding move, infielder Cole Tucker has been recalled from Triple-A to join the active roster.

Kansas City Royals catcher Salvador Perez (back) has been scratched from Monday's lineup against the Blue Jays in Toronto due to back tightness. Freddy Fermin will now catch right-hander Jonathan Bowlan and hit sixth in the batting order against Blue Jays right-handed rookie Yariel Rodriguez. For now, fantasy managers should consider Perez as day-to-day, but this is certainly something that could sideline the 33-year-old veteran for multiple days or even land him on the injured list. We'll keep an eye out for more updates on Perez, but for now, fantasy managers will obviously want to remove him from their starting lineups on Monday. Injury aside, Perez has been excellent through the season's first month, hitting .340/.398/.592 with a .990 OPS, seven home runs and 26 RBI in his first 103 at-bats.

The Colorado Rockies are officially calling up outfield prospect Jordan Beck to the major-league roster on Monday. Beck received the news on Sunday night and is traveling to Miami on Monday to join the team when they start their series with the Miami Marlins on Tuesday. The team's No. 4 prospect, per MLB Pipeline, gets his first big-league call-up after hitting .307 (31-for-101) with five homers, 10 doubles, 28 RBI, five stolen bases and 24 runs scored in 25 games with Triple-A Albuquerque. The 23-year-old former 38th overall pick in 2022 out of Tennessee should play every day with Nolan Jones (back) going on the injured list on Monday. Beck should immediately become attractive in most fantasy formats in the short term for his raw power from the right side of the plate as long as he's playing every day in Colorado.

Arizona Diamondbacks designated hitter Joc Pederson and outfielder Jake McCarthy are both out of the lineup on Monday against left-hander James Paxton and the Los Angeles Dodgers. As a result, rookie infielder Blaze Alexander is the DH and is batting leadoff, while outfielder Randal Grichuk is in right field and hitting sixth in the batting order. Pederson is hitting a nice .296 (16-for-54) to begin his first season with the D-backs, but he's been afforded just three at-bats against left-handers. Alexander has really impressed so far in his first season in the big leagues and will be a pretty attractive DFS option in the leadoff spot on Monday. Grichuk will be more of a deep sleeper in daily lineups, but he does have a homer and two RBI while hitting .267 against Paxton in 15 career at-bats.
