When pitchers and catchers reported Feb. 18, I posted five key questions the Mets faced heading into the season. Let’s revisit those questions at the All-Star break.

Question 1: What is this team’s attitude?

Assessment: By all accounts, it has been superb. There is a different chemistry in the Mets clubhouse than I have previously seen. The Mets have shown a remarkable resiliency to bounce back from adversity and Sunday’s win is just another example. There have been no issues about a lack of hustle, and no finger pointing. Both Jeff Francoeur and Angel Pagan said the right things about the prospect of reduced playing time as Carlos Beltran is about to be activated from the disabled list. The only sour note was, surprise, Oliver Perez’s refusal to accept a minor league assignment, instead, waiting for the disabled list to leave the roster to work on his issues.

Question 2: How healthy is this team?

Assessment: Injuries sabotaged the 2009 season, and injuries have cost Beltran and Daniel Murphy in the first half, and Jose Reyes for nearly a month. Beltran is due back to start the second half, but there’s no timetable for the return of Murphy, who reinjured his knee while on a rehab assignment. Murphy was playing second base at the time in preparation for a position change. After treating Reyes with kid gloves in the wake of his thyroid issue, the Mets rushed him back from an oblique injury, which he aggravated Saturday. There’s no telling how long he’ll be out. Luis Castillo is on the disabled list and his is another injury where the Mets tried to have him play through. Fortunately, his replacement, Ruben Tejada, has more than filled the void. Reliever Kelvim Escobar, penciled in as a set-up man, is out for the year with a shoulder injury. The Mets are still trying to find an eighth-inning solution. Oliver Perez and John Maine are currently on the disabled list.

Question 3: What is the status of the three pitching questions, Mike Pelfrey, Oliver Perez and John Maine?

Assessment: Pelfrey made a point of saying he understood this trio represented a significant key to the Mets’ success this season. Perez and Maine are on the disabled list, but the team upgraded with R.A. Dickey and Hisanori Takahashi. Pelfrey was superb for much of the first half but has been going through a dead arm period and has been largely ineffective over his last five starts. Perez balked at a minor league assignment, but an injury was found that conveniently landed him on the disabled list. He has been sound, and somewhat effective, in his rehab assignment. Look for the Mets to activate him shortly after the break and send Takahashi back to the bullpen. There’s no timetable for Maine’s return.

Question 4: Who is fifth starter?

Assessment: Fernando Nieve, Jon Niese, Nelson Figueroa and Hisanori Takahashi were in the mix in the spring, but Niese won the job and has been very good since coming off the disabled list. Niese has been so good that management tabbed him untouchable when Seattle asked for him in trade discussions surrounding Cliff Lee. Figueroa is now in Philadelphia, while Nieve is in the bullpen. Takahashi replaced Perez in the rotation and pitched well at first, but clearly showed he’s more valuable in the bullpen. The Mets are searching for a fifth starter in the trade market, as there are lingering questions about Perez and Maine.

Question 5: What is the make-up of the bullpen?

Assessment: Jenrry Mejia went north with the pen in an undefined role, but eventually went to the minor leagues to work on being a starter, when he was injured. Losing Escobar went a large part in opening the door for Mejia, who threw hard, but never grasped the eighth-inning role. Bobby Parnell, who appeared to wash out last year, now appears to be the arm having the inside track in the eighth inning to start the second half. Ryota Igarashi was the guy at one time, but after a pulled a hamstring he hasn’t been the same since. He’s now in the minor leagues. Nieve and Pedro Feliciano were overworked early, and still have heavy workloads. The distribution of work should be improved when Takahashi goes back to the bullpen.
