Yet another miserable experience for Mets fans Saturday at Citi Field, with their team managing just two hits in a 5-0 loss to the awful Padres. Back down to a season-worst eight games under .500, at 30-38, the Mets will try Sunday to even this homestand at 3-3 before heading to St. Louis then Miami for a challenging road trip. It’s possible that for a select group of the announced 38,269 on hand — a bump for the 50 Cent postgame concert? — the most aggravation might have occurred before the game started, when beleaguered Mets general manager Sandy Alderson danced around the issue of a payroll increase and sounded wary of trading his impressive pitching surplus for an impact bat. Alderson has made some bold moves — the trades of Carlos Beltran and R.A. Dickey and drafting high-school players, for instance — to increase the Mets’ talent pool to its current level. If anything, the Mets need to be bolder, not less bold, as they try to leverage that pitching depth into steady respectability, if not contention. Alderson joined his manager Terry Collins and pitchers Jacob deGrom, Matt Harvey and Jon Niese in a question-and-answer session with Mets season-ticket holders at the ballpark, about four hours before first pitch. Not surprisingly, Alderson fielded the majority of the questions, one of which covered potential trades down the road. “I think one of the problems with trading pitching, no matter how much you have, is you can never have enough,” Alderson said. “We’ve used eight starting pitchers this season. If minor-league pitching is our strength, the question then becomes, ‘When do you trade some of that pitching for hitters?’ “We’re cautious about it. One of the things that makes us particularly cautious is knowing who can or can’t play in New York. If a guy plays well in Seattle, for instance, how is he going to do here in New York? You watch how Curtis [Granderson] carries himself — win or lose, strikeout or not — and there’s something to be said for a guy who knows how to play in New York. It’s a different environment.
