There’s apparently been too much good news for the Mets this week, so today we started to hear some bad news. First it was reported that Ruben Tejada had suffered a quad strain last night and was going on the disabled list. Omar Quintanilla got promoted to the big leagues in Tejada’s stead, but first he had to be put on the 40-man roster. That was accomplished when the Mets moved Frank Francisco — who recently suffered a setback with his elbow and hasn’t pitched since February — to the 60-day disabled list.

Quintanilla is hitting very well in Las Vegas, but there’s a very good chance that his .333/.419/.484 batting line won’t carry over to the major leagues. Oh well. It’s not as though Tejada was hitting well at all, anyway. He is an important part of the Mets’ future, though, so hopefully Tejada can get well soon and pick up his game when he’s healthy again.

We also learned today that Jon Niese has been suffering from tendinitis in his throwing shoulder. He’s actual been pitching much better lately, so this seems to be a legit ailment rather than an excuse for poor performance. Niese will miss his start on Saturday and hopefully will be healthy enough to avoid a trip to the DL.

The Yankees, meanwhile, have been getting good injury news. Yesterday we found out that Kevin Youkilis and Mark Teixeira would be back in the majors on Friday. Today’s news is that Andy Pettitte will make a start on Monday against the Indians.

Pettitte had been pitching pretty well (39 strikeouts and 15 walks in 49.1 innings) this season before getting hit with a trapezius muscle injury. His return means that either David Phelps or Vidal Nuno will leave the rotation. Phelps just got rocked by the Mets last night, so he’s the early favorite to be voted off of Yankee island. Nuno heads to the mound tonight.
