New rule makes Philly trip smooth for Satin

PHILADELPHIA -- As the Mets filtered out to take pregame batting practice Saturday, general manager Sandy Alderson suggested to Josh Satin that he join the team on the field.

"I'm allowed to?" Satin asked.

You are, Alderson replied. Though Satin was not active for Saturday's game against the Phillies, he was in Philadelphia as part of the "taxi squad" provision built into Major League Baseball's new Collective Bargaining Agreement. The Mets flew Satin in from Triple-A Buffalo in case they needed to place David Wright on the disabled list, an event that never took place.

Previously, players not on a team's active roster or disabled list were not allowed to show up to the park. If clubs were unsure whether a callup would be necessary, as the Mets were Saturday in the case of Wright, they typically flew in potential replacements and sequestered them in nearby hotels.

MLB eliminated the red tape prior to this season, allowing Satin to join the Mets for stretching and batting practice. Though Satin was not allowed to sit on the bench during the game, he could stay in the building and watch on a clubhouse television.

"It's kind of bizarre," Satin said. "But I knew the deal coming here. I don't even know what I was expecting. But if something happened, I was ready."

For Satin, it was a welcome diversion from the frigid temperatures at Buffalo, not to mention a chance to catch up with friends. It was also an affirmation that, should the Mets need help at any point going forward, he would be on the short list for a more traditional callup.

"I think of it like that for sure," said Satin, who was batting .250 with one home run in eight games for Buffalo. "If something happens, they believe in me enough that they could call me up here. Out of everything else, that's kind of what I'll take out of this."

Remaining at second, Murphy continues to learn

PHILADELPHIA -- The byproduct of David Wright's return to the lineup Saturday was that the Daniel Murphy third-base experiment never came to pass. Willing to shift to third in Wright's potential absence, Murphy instead stayed at second base, where he has played in each of the Mets' first eight games.

Though Murphy has hardly thrived at the position, committing his second error in Friday's game and struggling on double-play attempts in particular, manager Terry Collins believes the only way his second baseman will improve is by continuing to play.

"You better grow from it," Collins said. "I'm not going to keep pulling out every guy that we think has got a defensive liability. We can't do it. We don't have enough players. That's not fair. These guys, they've got to be able to make those plays, and I think Dan's going to be fine doing it."
