Red Sox place OF Nava on DL

The Boston Red Sox placed outfielder Daniel Nava on the 15-day disabled list Wednesday with a left wrist sprain and recalled catcher Ryan Lavarnway from Triple-A Pawtucket.

Nava, 29, was batting .251 with four home runs and 27 RBI over 65 games with the Red Sox this season.

The 24-year-old Lavarnway made his major league debut with the Red Sox in 2011 and hit .231 with two home runs and eight RBI over 17 games last season.

Boston also added pitcher Craig Breslow to the major league roster and optioned pitcher Clayton Mortensen to Pawtucket.

Breslow was acquired from Arizona on Tuesday and went 2-0 with a 2.70 earned run average in 40 relief outings for the Diamondbacks this year.

Mortensen earned the win in last night's victory over Detroit and sports a 1.17 ERA over 10 appearances with the Red Sox this season.
