Kansas City Royals closer James McArthur earned his 13th save of the season in Monday's 4-1 win over the Marlins. McArthur came in to pitch the top of the ninth inning up by three and turned in a 1-2-3 performance with a strikeout. The 27-year-old has earned the closer's role for a surprisingly solid Royals team, although his overall numbers haven't been great. He has blown four saves this season and has a 4.70 ERA, a 1.43 WHIP, and a 20.3% strikeout rate in 30 2/3 innings of work. His relative role security does provide fantasy value in deeper roto leagues, but his high ratio stats and low strikeout rate limit his overall fantasy upside.

Milwaukee Brewers closer Trevor Megill picked up his 16th save of the season in Monday's 6-3 win over the Rangers. Megill came in to pitch the top of the ninth inning up by three. He got the first two outs on a fly-out and a strikeout, hit a batter, and ended the game by striking out Adolis Garcia. The 30-year-old has emerged as the team's closer and a viable fantasy option, converting all but one save opportunity with a 1.85 ERA, a 1.03 WHIP, and a 30.6% strikeout rate in 24 1/3 innings of work. The Brewers are playing solid baseball, making Megill a mid-to-high-tier fantasy option in all leagues at this time.

The Chicago White Sox demoted outfield prospect Oscar Colas to Triple-A Charlotte on Sunday. Colas, 25, continues to operate between Charlotte and Chicago this season, but has gotten limited playing time when in the big leagues. Colas has always shown good power, but has yet to figure it out against big-league pitching. With the White Sox rostering one of the weakest rosters in the game and rostering the fragile Eloy Jimenez, Colas should get another chance at playing time as the summer goes on. He can safely remain on the waiver wire in all formats.

San Francisco Giants shortstop Nick Ahmed hit his first home run of the year during the bottom of the sixth inning in Monday's 5-4 win over the Chicago Cubs. Ahmed's homer was only the sixth extra-base hit he's delivered in 124 at-bats, but he also walked twice and is now slashing .250/.291/.323 with 13 RBI and 11 runs scored. He is no longer the middle infielder who popped a combined 35 home runs in the 2018 and 2019 seasons, as Ahmed has managed 16 homers since the start of the abbreviated 2020 campaign. Fantasy managers in deeper leagues might consider Ahmed, but he's safe to keep on waiver wires right now.

San Francisco Giants third baseman Matt Chapman hit his ninth homer of the season in Monday's 5-4 win over the Chicago Cubs. It was the first home run in June for Chapman, who took Justin Steele deep in the bottom of the fifth to start the Giants' comeback from a 4-0 deficit. Chapman has flustered fantasy managers, but his 2-for-4 effort that included two runs scored on Monday might push him out of his funk. He is slashing .233/.313/.394 with 31 RBI, yet ranks among the top 20 with 50 runs scored. The power will eventually return for Chapman, but as long as he continues to find his way across home plate, his ability to score runs justifies keeping him in lineups in most leagues.
