On September 5, 2006, he was traded to the Boston Red Sox to complete an August 31 deal for David Wells and was immediately added to the team's 40-man roster.[5][6] He was assigned to the Red Sox Double A franchise, the Portland Sea Dogs, who had just begun their Eastern League playoff run. Kottaras arrived for Game 2 of Eastern League Division Playoffs and continued playing with the Sea Dogs until they were crowned 2006 Eastern League Champions.[7]
Kottaras played the entire 2007 season for the Triple-A Pawtucket Red Sox. He reported for spring training in 2008 but was optioned back to Pawtucket on March 17, 2008.[8] Kottaras played the regular and post season 2008 schedule for Pawtucket.[9]
Then, after Pawtucket was eliminated from the International League playoffs, he was called up from Pawtucket to MLB on September 8, 2008, [10] and on September 13, 2008, made his MLB debut in the sixth inning of a game against the Toronto Blue Jays and scored the only run for the Red Sox that game.[11]
In 2009, Kottaras was knuckleball pitcher Tim Wakefield's personal catcher; while Jason Varitek caught the other pitchers in the rotation. After Wakefield went on the disabled list after the All-Star break, Kottaras followed suit with a lower back strain. He remained with Pawtucket until call ups on September 1. With Wakefield's first start in September, Red Sox manager Terry Francona had to decide whether to start Kottaras due to his familiarity with Wakefield or Víctor Martínez due to his bat and having made one start with Wakefield in which he caught the knuckleball very well for the first time.[12] Francona eventually chose Martínez.
Kottaras hit his first MLB home run on July 3, 2009, against the Seattle Mariners'Mark Lowe in the bottom of the 11th. For the season, he finished fifth in the league in passed balls, recording eight in 39 games.[13]
