• Alderson confirmed after Saturday's game that reliever Vic Black, whom the Mets got in the Byrd trade, will join the team on Sunday, the first day of expanded rosters. He is scheduled to arrive around noon ET and should be available.
Black made his Major League debut with the Pirates at Nationals Park on July 25 and pitched a scoreless third of an inning. In three appearances for Pittsburgh, he gave up two runs over four innings.
• The Mets optioned left-handed reliever Robert Carson to Triple-A Las Vegas after Saturday's game. The 51s were on the verge of clinching a playoff berth, but Alderson said their pitching is thin and that Carson will help.
• In talking about Black's arrival, Collins quipped that, "We're playing so late at night, anybody can get in." Sunday's game starts at 8:05 p.m. ET for ESPN's Sunday Night Baseball, and the Mets then have to fly to Atlanta for Monday's 1:10 p.m. Labor Day game against the Braves.
