World traveler Ruben Amaro Jr. scouts Yasmany Tomas

MIAMI — Ruben Amaro Jr. rejoined his team Tuesday after two international fact-finding trips, which culminated in a private workout Monday with coveted Cuban outfielder Yasmany Tomas. A cadre of Phillies officials watched Tomas, who turns 24 in November, at the team's Dominican Republic complex.

That showcase came after a recent trip to Japan by Amaro, who was accompanied by senior advisor Charlie Manuel and Sal Agostinelli, the Phillies' international scouting director.

"We're keeping our mind open on every opportunity," Amaro said.

Tomas is the prize, and he is expected to attract serious competition for his services. Major League Baseball has not yet approved the power-hitting corner outfielder for free agency. That clearance is expected soon.

The Phillies are just one of many teams to schedule a private session with Tomas. They arranged a similar situation with Rusney Castillo, another Cuban import, but did not bid near the $72.5 million that Boston committed.

Tomas, who is three years younger than Castillo, could command at least $100 million on the open market. The Yankees and Giants are viewed as serious suitors.

Amaro would not comment on Tomas' potential, seeing as he is an unsigned player. The Phillies have a need for a middle-of-the-order bat. But just about every team could use one.

There are few attractive outfielders on this winter's market. Tomas, because of his age and the recent success of Cuban players, is an enticing option.

"The talent crop of free agency has been dwindling pretty significantly," Amaro said. "There is probably more pitching options out there than there are bats. That's a little more fertile than in recent years. I think bats, in general, have been a dwindling asset."
