Mets morning briefing 9.3.12

Making his first start in a week, Jason Bay delivered his third grand slam as a Met -- a first-inning shot against Mark Buehrle. The Mets went on to beat the Miami Marlins, 5-1, Sunday to sweep the three-game series.

The Mets now play a Labor Day matinee in St. Louis, with Collin McHugh trying to build on the seven scoreless innings he tossed in his major league debut against the Colorado Rockies. McHugh opposes right-hander Joe Kelly (4-6, 3.61 ERA) at 2:15 p.m. ET.

Monday's news reports:

• Bay had only his fourth two-hit game of the season. The Mets' bullpen tossed four scoreless innings in relief of Chris Young and has now limited opponents to one earned run in its past 22 1/3 innings. The Mets swept a series for the first time since June 20, against the Baltimore Orioles at Citi Field. Read game recaps in the Post, Newsday, Star-Ledger, Record, Daily News and Times.

Jenrry Mejia allowed six runs in six innings in Triple-A Buffalo's 6-0 loss at Lehigh Valley. St. Lucie posted its club-record 83rd victory in its regular-season finale and opens the playoffs Tuesday at Jupiter. Brooklyn lost to Staten Island, 1-0, to fall into a first-place tie in the New York-Penn League wild-card standings with three games remaining. Read Sunday's full minor league recap here.

• Mejia last appeared in the majors in September 2010, before Tommy John surgery. Read about his comeback here. Fellow expected call-up Jeurys Familia may pitch an inning of relief today in Buffalo's finale. The other players expected to join the Mets (along with already promoted Zach Lutz, Mike Nickeas and now McHugh): Jordany Valdespin, Fred Lewis, Elvin Ramirez and possibly Matt Tuiasosopo.

TRIVIA: Against which team was Bay's first grand slam as a Met?

Sunday's answer: Expected call-up Fred Lewis played parts of four seasons for the San Francisco Giants.
