Bobby V: David Ortiz 'feels better'

OAKLAND -- Red Sox manager Bobby Valentine said it looks like David Ortiz is doing better since having an injection in his injured Achilles.

Valentine said Ortiz "feels better," but doctors are not planning on having Ortiz rejoin the team this weekend. Valentine said it's possible Ortiz could meet the team next week in Seattle, but it seems more likely he'd be back next weekend in Boston.

Ortiz, who was placed on the disabled list Monday, underwent a platelet-rich plasma (PRP) injection this week.

Left-handed pitcher Franklin Morales, who's on the DL with a tired shoulder, has been throwing, Valentine said. Valentine said Morales will pitch again this season, "without a doubt."

Left-hander Rich Hill joined the team Friday, and he is expected to be activated when rosters expand Saturday. Valentine said the Red Sox aren't expecting to add any more players from Triple-A Pawtucket or Double-A Portland until their seasons end. Pawtucket had a chance to clinch a berth in the International League playoffs on Friday night. Portland's season ends Monday.

Valentine said he would be in favor of changing the rules that allow teams to expand their rosters up to 40 players in September.

"You play the entire season to build a competitive advantage between your team and the competition, and then it's thrown out the window in the last month of the season," Valentine said.

Valentine said he'd actually be in favor of expanding the rosters in April.

"You get to see guys play in April under the lights and pick a real team and then you go to battle with that team through the postseason," he said.
