UPDATE (9:58 p.m.): After a nearly three hour delay, Mike Pelfrey took the mound for the Mets.
UPDATE (7:37 p.m.): According to Ken Davidoff's Twitter account (@KenDavidoff), the "Mets are hoping that the bad weather clears by 8:30 p.m."
The Mets also posted a weather alert on the team's scoreboard that read, "Inclement weather is approaching the area. For your safety, please make your way into the covered areas of the concourse."
Francisco Rodriguez's return to Citi Field has been pushed back, if only for a short time, because of the weather.
The Mets' grounds crew rolled out the tarp delaying the start of the Mets-Brewers game because of rain in the forecast.
Rodriguez, who was dealt to Milwaukee hours after the All-Star game, hasn't played in Citi Field since the trade. He has a 2.03 ERA in 13 1/3 innings with Milwaukee, serving primarily as the team's setup man.
Shaun Marcum, who is 10-3 with a 3.50 ERA, is Milwaukee's scheduled starter. Mike Pelfrey (6-9, 4.58 ERA) is scheduled to take the hill for the Mets.
