MLB notebook: Cubs designate Marmol for assignment
• The Cubs designated former All-Star Carlos Marmol for assignment Tuesday, parting ways with the struggling reliever. Chicago has 10 days to trade or release him or send him outright to the minors if he clears waivers. The 30-year-old Marmol was 2-4 with two saves and a 5.86 ERA. The Cubs also gave infielder Ian Stewart his unconditional release.
• The Red Sox optioned struggling third baseman Will Middlebrooks to Triple-A Pawtucket. Jose Iglesias will be the team's third baseman, “for the short run,” according to manager John Farrell.
• Former Cubs pitcher Kerry Wood discovered a body floating in Chicago's Belmont Harbor on Monday morning, the Chicago Tribune reported. Wood, who was paddle boarding, called 911 to report the body. The Tribune reported the victim was a 40-year-old man who had been reported missing by a nursing home last week.
• Nationals outfielder Bryce Harper started his rehabilitation assignment at Class-A Potomac as he recovers from left knee bursitis that has sidelined him for nearly a month. Manager Davey Johnson said Harper likely won't rejoin the Nationals this weekend when they travel to New York.
• The Dodgers activated center fielderMatt Kemp from the 15-day disabled list.
• Diamondbacks first baseman Eric Hinske's suspension for participating in a June 11 brawl at Dodger Stadium has been reduced to one game from five.
• The Diamondbacks reinstated second baseman Aaron Hill from the 15-day disabled list. Hill has been out since being hit by a pitch thrown by the Pirates' James McDonald on April 9.
