Ruben Amaro Jr.’s offseason plan consisted of this: Get the Phillies’ core players healthy, hope they produce, add some complementary pieces, fix the eighth inning, and make a push at returning to the postseason before Father Time catches up with the club and some key players’ contracts run out.

Sixty-four games into the season, the plan is not working. The Phillies are 31-33, 8½ games back in the NL East and 6½ games out of the second wild-card spot.

Several of the team’s big guns -– Roy Halladay, Chase Utley and Carlos Ruiz –- have been banged up. Others, such as Ryan Howard, have not produced. While others, such as Cole Hamels and Jimmy Rollins, have been inconsistent. Domonic Brown, Cliff Lee and Jonathan Papelbon have been standouts.

Amaro’s complementary additions have been less than impressive. Centerfielder Ben Revere has struggled at the plate and in the field, rightfielder Delmon Young has shown just a few flickers of production in the month he’s been active and eighth-inning reliever Mike Adams has shown a drop in overall stuff and has had trouble staying healthy. Third baseman Michael Young has been as advertised in the field: He catches what he gets to, but his range is quite limited. At the plate, Young’s lack of extra-base pop has been alarming.

In an interview with CSNPhilly.com, Amaro acknowledged that things have not gone well for his club. He is heartened, however, that the Phillies remain within striking distance with more than half a season to play.

“It’s a good sign that we’ve gotten less than typical production from some of our major players and we are still where we are,” he said.

Amaro spoke on a number of topics, starting with Revere and young players in general.
