Source: 'Doubtful' Sox will add Young

The Red Sox have a void at third base after trading Jose Iglesias on Tuesday night, but it is “doubtful” they will fill that spot by acquiring Phillies third baseman Michael Young before Wednesday’s trade deadline, according to a baseball source.

At least for the short term, the Red Sox are calling up infielder Brock Holt, and not Will Middlebrooks, from Triple-A Pawtucket to take the place of Iglesias on the big club’s roster, according to another source.

A team source said the Sox would probably go with someone currently on the roster than add a third baseman via trade.

Brandon Snyder has played third base in 13 games for the Red Sox this season while Holt has played in 9. Middlebrooks began the season as the starter at third but was demoted in June after hitting .192 in 53 games.

In Pawtucket, he is hitting .257 with 8 homers and 30 RBIs in 36 game. He and shortstop prospect Xander Bogaerts are in Wednesday’s PawSox lineup for a noon game against Norfolk.

Young has told Phillies GM Ruben Amaro Jr. that at this point he will only waive his no-trade clause to return to the Texas Rangers, sources said Tuesday.

Young spent the first 13 years of his career in Texas before being traded to Philadelphia in December.

Sources said that Young will consider other teams if there is no chance that he can go back to the Rangers. Young's second choice appears to be the Red Sox, according to sources. The Yankees could also get into the mix if Texas and Boston pass on Young.

On Wednesday morning, FoxSports.com's Ken Rosenthal tweeted that Young would indeed waive his no-trade clause to go to Boston:
