The Washington Nationals placed starter Trevor Williams on the 15-day injured list with a right elbow sprain Friday, two days after the veteran right-hander gave up a season-high seven runs in an 11-2 loss to Detroit.

Williams is 3-10 with a 6.21 ERA in 17 starts this season and is tied for second in the National League in losses. He agreed to a two-year, $14 million deal after going 6-1 with a 2.03 ERA last year despite being limited to 13 starts because of strained muscle in his throwing arm.

Washington recalled right-hander Ryan Loutos from Triple-A Rochester, a day after demoting him. Loutos is 1-0 with a 13.50 ERA in eight games with the Los Angeles Dodgers and the Nationals this season.

The Nationals also activated catcher Keibert Ruiz from the injured list and optioned catcher Drew Millas to Rochester. Ruiz had been sidelined with a concussion after getting hit by a foul ball on June 23.

Cubs starter Taillon out at least month

Chicago Cubs starter Jameson Taillon may miss “more than a month” with a right calf strain, manager Craig Counsell said Friday after the team placed the veteran right-hander on the injured list.

Taillon is 7-6 with a 4.44 ERA and a mainstay in the NL Central leader’s rotation despite some ups and downs in his ninth major league season. The 33-year-old has lost three straight games, with a 10.66 ERA in that span, after winning five in a row.

Taillon, who had been scheduled to start Saturday, sustained the injury while running after a bullpen session on Thursday.

“He felt a grab yesterday,” Counsell said. “He’s going to miss a pretty significant amount of time.”

In a corresponding move, the Cubs recalled lefty Jordan Wicks from Triple-A Iowa before their game against the St. Louis Cardinals.

Wicks is expected to work from the bullpen, although 11 of his 12 appearances for Iowa were starts.

Forearm issue lands Yanks’ Schmidt on IL

Yankees pitcher Clarke Schmidt was placed on the 15-day injured list because of right forearm soreness on Friday, one day after his start at Toronto was cut short following three innings.

A 29-year-old right-hander, Schmidt was set to have an MRI on Friday.

Illness puts Mets’ Buttó on IL

New York Mets reliever José Buttó was put on the 15-day injured list Friday with an unspecified illness, the team’s 13th pitcher on the IL.

“We’re not going to get into the details of it out of respect of Buttó, but we don’t anticipate this being a long term,” Mets manager Carlos Mendoza said. “We expect him to be back right after the All-Star break.”
