New York Yankees ace Luis Severino will miss Opening Day because of an inflamed right shoulder that caused the two-time All-Star to be scratched from his first scheduled spring start on Tuesday.

Severino won't throw for two weeks, Yankees manager Aaron Boone said after a 5-1 victory over Atlanta.

"Obviously, anytime a starting pitcher and a guy like Sevie walks off while he's warming up to start a game, you always get worried and concerned about that," Boone said. "But it sounds like the shoulder is pretty clean, it's just the inflammation issue."

Severino, a 25-year-old righthander who is 41-25 with a 3.51 ERA in his career, was slated to face the Braves but was replaced after feeling discomfort after throwing his first slider during his pregame bullpen session.

Bigger rosters?

MLB and the players' union are near an agreement to expand active rosters by one to 26 starting in 2020 as part of a deal that would include a commitment to discuss larger economic issues after Opening Day this year.

As part of the deal, the active limit from Sept. 1 to the end of the season would be lowered from 40 to 28 beginning next year, people familiar with the negotiations told the Associated Press. A limitation on September call-ups would end parades of relief pitchers that cause some games to stretch on.

There would be a maximum of 13 pitchers for most of the season and 14 from Sept. 1 on, the people said. The new 26-player maximum also would apply to the postseason.

Wooing Trout

New Philadelphia slugger Bryce Harper has again lobbied for Mike Trout to join the Phillies in 2021, a possible violation of MLB's tampering rule.

Trout, a two-time AL MVP with the Los Angeles Angels, grew up near Philadelphia, attended the Phillies victory parade in 2008 as a 17-year-old and has season tickets for the Eagles. The 27-year-old outfielder is set to become a free agent after the 2020 season.

"If you don't think I'm going to call Mike Trout to come to Philly in 2020, you're crazy," Harper told SportsRadio 94WIP in Philadelphia on Tuesday.

The Phillies gave Harper a 13-year contract last week, the largest deal in baseball history at $330 million.
