George Sherrill, a 2008 All-Star, is one of them.
The Royals announced a series of minor transactions on Tuesday, including the signing of three longtime MLB veterans to minor-league deals:

Sherrill, a 35-year-old left-handed reliever, has pitched in the big leagues for nine years with a 3.77 ERA in over 324 innings pitched. He appeared in only two games with the Seattle Mariners last season before undergoing Tommy John surgery, and he may not be ready to pitch until well into next season.
Wheeler, a 34-year-old right-handed reliever, has pitched for 5 teams in 13 years with a career 3.98 ERA. He was very ineffective in his time in Cleveland last season, with a 8.76 ERA in 12 innings of work.
Taveras, a 30-year-old CF, has played for four teams in seven MLB seasons, but has not appeared in the major leagues since 2010.
