We hear a lot of talk about buyers and sellers this time of year, but as Ken Rosenthal of FOX Sports points out in his latest column, some teams will do neither this summer and other teams will do both. Here are Rosenthal’s latest notes with less than four weeks to go before July 31st:

• The Red Sox could be positioned to trade an outfielder this month if their rehabbing players return as expected. Boston figures to pursue starting depth in trades; the Red Sox aren’t considering trades involving Josh Beckett.
• The Yankees will probably not sign Josh Hamilton or Cole Hamels this offseason, since they aim to avoid the MLB luxury tax by 2014 and that means cutting back on extravagant free agent signings.
• Under GM Frank Wren the Braves won more games while spending less money than every team but the Rays from 2009-11, Rosenthal notes. 
• If the Blue Jays trade players on the brink of free agency such as Edwin Encarnacion and Kelly Johnson, they’d look to acquire players who can help them win next year. And if the Blue Jays don’t like what other teams are offering, they’ll keep their potential free agents. Toronto’s not likely to overpay in a “go for it” trade, Rosenthal writes.
• The Blue Jays aren’t trading Colby Rasmus, who has become more driven, according to a team official. 
• Rosenthal suggests the Athletics could look to acquire players midseason if they stay in the playoff mix. Bartolo Colon is the player the A’s are most likely to trade, Rosenthal writes.
• The Mets are actively seeking relief help, but it’s highly doubtful they’d trade for Huston Street, who publicly criticized Mets bench coach Bob Geren last year. The Mets, who insist they won’t trade top prospects, are likely to wait until the end of the month before making any trades.
• The Cardinals wouldn’t be willing to meet the Brewers’ asking price for Zack Greinke, Rosenthal notes. St. Louis is more likely to pursue a mid-rotation starter.
• The Diamondbacks believe they need a third baseman more than a starting pitcher.
