Max Scherzer will be the opening-day starter for the Washington Nationals instead of Stephen Strasburg, who has made the previous three opening-day starts.
Manager Matt Williams made the announcement before Monday's game against the New York Yankees.
Scherzer, who never started on opening day for the Detroit Tigers despite winning the Cy Young Award in 2013, signed a seven-year, $210 million contract with Washington in the offseason.
He was 82-35 with a 3.52 ERA in his five seasons with Detroit.
Williams didn't announce the rest of his rotation. This spring, the Nationals have gone with Scherzer, Jordan Zimmermann, Strasburg, Doug Fister and Gio Gonzalez.
A lawyer for rooftop clubs around Wrigley Field said the Chicago Cubs are illegally trying to drive his clients out of business by constructing a large video board at the stadium.
U.S. District Judge Virginia Kendall heard arguments on whether she should order a halt to construction of the right-field sign that would block several rooftop views.
Lawyer Thomas Lombardo said the Cubs have tried to "bully" his clients into raising ticket prices or selling their clubs. The Cubs currently have a revenue-sharing agreement with the rooftop owners.
Indians manager Terry Francona said he doesn't expect slugger Nick Swisher to be ready for the team's April 6 season opener at Houston.
