Outfielder Gabe Kapler and infielder Enrique Wilson are the veterans who headline the group that also includes catcher Ken Huckaby, utilityman Willie Harris, middle-infield prospect Dustin Pedroia and outfielder Dustan Mohr.
Other invitees include right-handers Tim Bausher, Matt Ginter and Jimmy Serrano, as well as lefthanders Craig Breslow, Mike Bumatay, Mike Holtz and Phil Seibel.
Infielders Trent Durrington, Luis A. Jimenez, Rodney Nye and Josh Pressley will join outfielders Luke Allen, Ron Calloway and Tyler Minges in competing for attention and roster spots in the organization.
Kapler, who helped Boston to the 2004 World Series title, returns to the Red Sox after batting .247 with one homer and 9 RBIs in 36 games in 2005, a season that came to an abrupt end when he ruptured his left Achilles' tendon Sept. 14 in Toronto. After beginning last season with Japan's Yomiuri Giants, Kapler, a career .271 hitter, re-signed with the Red Sox on July 15 and joined the club following a disabled list stint and rehab assignment on July 30.
Many Red Sox fans remember former Yankee Enrique Wilson as the thorn in the side of Pedro Martinez. Wilson is a veteran of all or part of nine Major League campaigns with Cleveland (1997-2000), Pittsburgh (2000-01), New York (2001-04) and the Chicago Cubs (2005). The 32-year-old switch-hitter has seen time at every infield position and owns a career .244 batting average with 22 home runs and 141 RBIs in 555 major league games.
Harris, 27, joins the Red Sox in 2006 after spending the last four seasons in the Chicago White Sox organization. The left-handed hitter, who earned a World Series ring last year, has a career .242 batting average with 25 doubles, four triples, five home runs, 52 RBIs, 121 runs and 49 stolen bases in 322 Major League games.
Huckaby will battle with John Flaherty and Josh Bard for the back-up position to Jason Varitek. Huckaby has spent all or part of five Major League seasons with Arizona (2001), Toronto (2002-03, 2005), Texas (2004) and Baltimore (2005), returning to the Blue Jays last season and batting .207 with four doubles in 35 games.
Mohr is a career .252 major league hitter with 46 homers and 151 RBIs in 476 games with Minnesota (2001-03), San Francisco (2004) and Colorado (2005).
Pedroia was named the Red Sox's 2005 Minor League Offensive Player of the Year and earned a spot on the Double-A Eastern League's postseason All-Star squad. Boston's first pick in the 2004 First-Year Player Draft advanced to Triple-A Pawtucket from Double-A Portland on June 22 after batting .324 with a .409 on-base percentage, 19 doubles, eight homers, 40 RBIs and 35 runs in 66 games for the Sea Dogs.
