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. Millas hit .143 with an RBI in three games.

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.”

The IL move is retroactive to Tuesday. 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. He was 1-3 with one save and 4.06 ERA with the Triple-A affiliate.

Wicks appeared in two games with the Cubs in April, pitching two innings and going 0-1 with a 13.50 ERA.

“He’s got to come up here and attack the strike zone and get himself in favorable counts ... to be effective,” Counsell said.

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.

New York also recalled right-hander Scott Effross and left-hander Jayvien Sandridge from Triple-A Scranton/Wilkes-Barre.

Right-hander Clayton Beeter had been optioned to the RailRiders after replacing Schmidt on Thursday night and taking the loss in the 8-5 defeat as the Yankees were swept in a four-game series against the Blue Jays and dropped out of the AL East lead.

Schmidt allowed three runs, four hits that included George Springer’s two-run homer and two walks. He said he’s been dealing with soreness in his arm since his June 4 outing against Cleveland.

Illness puts Mets’ Buttó on Injured list

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.”

Mendoza said he didn’t anticipate that Buttó will need to go on a minor league injury rehabilitation assignment. A 27-year-old right-hander, Buttó is 2-1 with a 2.47 ERA in 31 relief appearances, the last a two-inning outing at Pittsburgh last Saturday.

New York recalled right-hander Chris Devenski from Triple-A Syracuse. Brought up for the fourth time this season, the 34-year-old right-hander has made four appearances for the Mets.
