After the Mets were blanked by rookies Joe Blanton (above) and Huston Street last night at the Oakland Masoluem, Newsday’s David Lennon reviews Omar Minaya’s options.

Last night was another not-so-subtle hint that the Mets need offensive help more than anything else, and with a surplus of starting pitching, they have the ability to either reload their rotation or swap a pitcher like Jae Seo or Yusmeiro Petit for a bona fide run-producer.

The position in question is first base, but the two most attractive sluggers — the Rockies’ Todd Helton and the Brewers’ Lyle Overbay — appear to be longshots. Colorado would love to deal Helton, but a contract that pays him $141.5 million through 2011 makes him pretty much radioactive to other clubs.

As for the more attractive Overbay, the Brewers insist he isn’t going anywhere, even though team officials sent mixed signals this week by calling up Prince Fielder for an interleague series at Tampa Bay.

Overbay is what the slumping Mientkiewiecz is supposed to be — a lefthanded gap hitter who can drive in runs, and he’s batting .285 with eight homers in 61 games.

“It’s rough,” Minaya said of the trade market. But things will get only worse for his team if he doesn’t get help.
