Carlos Marmol's volatile run with the Chicago Cubs is likely over. The former All-Star with 117 career saves was designated for assignment Tuesday.
Marmol, 30, went 2-4 with two saves and a 5.86 ERA in 31 relief appearances this season. He struck out 32 and walked 21 batters in 27 2/3 innings pitched.
Outfielder Brian Bogusevic was recalled from Triple-A Iowa and joined the team in Milwaukee for the start of a three-game series.
The Cubs also announced the release of third baseman Ian Stewart, two weeks after his disgruntled Twitter tirade.
Stewart has about $1 million left on a $2 million guaranteed contract. He suspended him without pay two weeks ago while with Triple-A Iowa after a series of harsh tweets expressing his anger over his status within the organization.

---Los Angeles Angels left-hander Jason Vargas will have surgery this week to remove a blood clot from an area near his left armpit, and is expected to miss three weeks to a month.
Vargas, 30, was placed on the 15-day disabled list Friday. He was 6-4 with a 3.65 earned run average in 14 starts this season. He was American League pitcher of the month in May, when he went 5-0 with a 2.30 ERA.

---Arizona Diamondbacks second baseman Aaron Hill returned from the 15-day disabled list Tuesday, after missing more than two months with a broken hand.
Hill, 31, hasn't played since April 14, when he was batting .306 with two home runs and six RBIs in 10 games. He went 9-for-24 with a triple and a double in six rehab games with Triple-A Reno.

---The Washington Nationals placed Dan Haren on the 15-day disabled list Tuesday, retroactive to June 23, with right shoulder inflammation.
Though Haren told reporters that he felt he could pitch through the issue, the Nationals wanted the righty to take time to heal. He signed a one-year, $13 million contract in the offseason, but has a 6.15 ERA in 15 starts this season.

---Minor-league pitcher Michael O'Connor was suspended for 50 games without pay on Tuesday after testing positive for a performance-enhancing substancce, the office of the commissioner announced.
The free-agent left-hander's drug test showed metabolites of Trenbolone, which is a banned substance. O'Connor, 32, had signed a contract with the Minnesota Twins in December but was released in May after pitching for Triple-A Rochester. He last pitched in the major leagues for the New York Mets in 2011, going 0-1 with 2.70 ERA in 6 2/3 innings.
The suspension will take effect once he signs with an organization.
