Arenado (forearm) is playing third base and batting sixth Tuesday against Atlanta.

Advice: Arenado missed a pair of games with left forearm soreness, but he's back in the starting nine for Tuesday's contest. Prior to the injury, Arenado was batting 17-for-66 (.258) in June with six RBI and four runs. Rotowire.com Yesterday, 12:10 pm

McArthur earned a save against the Marlins on Monday, striking out one batter in a perfect inning of work.

Advice: McArthur entered in the ninth frame with Kansas City up by three runs and made quick work of Miami, retiring the side in order on 10 pitches. That netted him his first save since June 6 and his 13th overall this season. McArthur's 18-day span between saves was of no fault of his own -- he didn't see any save opportunities during that stretch, and the only save by any KC pitcher during that period came in a game during which McArthur was used in a high-leverage spot and ended up with the victory. With that in mind, McArthur remains the top option for save chances in the Royals' bullpen. Rotowire.com Monday, 10:36 pm

James McArthur tossed a scoreless ninth inning and picked up the save against the Marlins on Monday.

Advice: The save was McArthur’s 13th of the season. He’s been a little shaky this season with a 4.70 ERA, but the Royals don’t necessarily have a better option to turn to for saves. It was just McArthur’s second save in the month of June, but it looks like the Royals will continue to lean on him when the opportunity arises. Rotoworld Monday, 7:45 pm

Padres manager Mike Shildt said Monday that Darvish (groin) won't be activated from the 15-day injured list to start Tuesday versus the Nationals due to "a little" right elbow inflammation, Dennis Lin of The Athletic reports.

Advice: Darvish had been slated to return from close to a month-long absence with a groin injury, but it's an elbow issue that will delay his activation even further. Shildt's wording would seem to suggest that Darvish is dealing with a minor setback, but a return to the rotation next week isn't guaranteed, especially after Darvish missed the final month of last season with a bone spur in the elbow. Adam Mazur was recalled from Triple-A El Paso and will start Tuesday. Rotowire.com Monday, 3:55 pm

Major League Baseball suspended Diaz for 10 games Monday for violating prohibitions on foreign substances, Jon Heyman of the New York Post reports.

Advice: Diaz was ejected from Sunday's 5-2 win over the Cubs after failing the "sticky substance" test from the crew chief upon entering the game in the bottom of the ninth inning. The suspension will go into effect beginning with Tuesday's game against the Yankees, and assuming he elects not to appeal the ban, the 30-year-old closer won't be eligible to pitch until July 6 against the Pirates. Adam Ottavino and Reed Garrett will be the likely candidates to step in for save opportunities during Diaz's absence. Rotowire.com Monday, 3:27 pm
