Roberto Osuna, Ken Giles, more relievers move as trade deadline nears

Closers Roberto Osuna and Ken Giles switched spots. Adam Warren and Zach Duke moved into the Seattle bullpen. And Lance Lynn got a new look in pinstripes.

A day before the deadline to make trades without waivers, there were a flurry of deals Monday.

Hoping they could improve their bullpen without causing friction in the clubhouse, the defending World Series champion Houston Astros acquired Osuna from the Toronto Blue Jays for Ken Giles and two pitching prospects.

The 23-year-old Osuna was a first-time All-Star last season, his second as the Blue Jays’ full-time closer, and finished with 39 saves and a 3.38 ERA.

But he hasn’t pitched in the majors since May 6 because he’s been serving a 75-day suspension under Major League Baseball’s domestic violence policy. That suspension ends Sunday. Osuna was charged in May with one count of assault in Toronto, a charge that remains pending.

The Astros have a zero-tolerance policy on domestic violence and released former prospect Danry Vasquez in March after video leaked of him hitting his girlfriend. Houston pitchers Justin Verlander and Lance McCullers Jr. used social media to voice their disgust about Vasquez’s actions after the video became public.

Astros general manager Jeff Luhnow said he reached out to several players and coaches before making the deal, and he clarified that the team policy does not apply to conduct that occurred when a player wasn’t in the Houston organization.

“Quite frankly, I believe you can have a zero-tolerance policy and also have an opportunity to give people second chances when they have made mistakes in the past, in other organizations,” Luhnow said. “That’s kind of how we put those two things together.”

Houston’s closest competitors in the A.L. West, the Mariners, also added to their relief corps. They got Duke from the Minnesota Twins for a pair of minor leaguers and acquired Warren from the Yankees, also for two minor leaguers.

New York, competing with Boston in the A.L. East and with Seattle in the wild-card race, also made a move to replace Warren, acquiring Lynn from the Twins for first baseman/outfielder Tyler Austin and right-handed prospect Luis Rijo.

The 31-year-old Lynn made 20 starts for the Twins, going 7-8 with a 5.10 ERA. The righty is likely to become a long reliever with the Yankees.

New York has Luis Severino, Masahiro Tanaka, CC Sabathia, Sonny Gray and newly acquired J.A. Happ in its rotation, although Lynn could fill in if a starter is sidelined by injury.
