Red Sox sign infielder Ryan Roberts
To make room for Roberts on the 25-man roster, the club optioned infielder Brock Holt to Triple-A Pawtucket, and made room for Roberts on the 40-man roster by transferring right-handed pitcher Steven Wright to the 60-day disabled list.
In eight major-league season, Roberts, 33, has a .245 average with 71 doubles, 46 home runs and 169 RBIs over 1,481 at-bats with the Toronto Blue Jays (2006-07), Texas Rangers (2008), Arizona Diamondbacks (2009-12), and Tampa Bay Rays (2012-13).
In 2013, Roberts batted .247 in 162 at-bats with six doubles, five homers, 17 RBIs over 60 games.
Holt, 25, returns to Pawtucket after getting called up for one game but he did not play. He is 4-for-11 with two doubles, two walks, three runs scored, and a stolen base in three games with Pawtucket this season.
