The 2003 team was known as the "Cowboy Up" team, a nickname derived from first baseman Kevin Millar's challenge to his teammates to show more determination. In the 2003 American League Division Series, the Red Sox rallied from a 0–2 series deficit against the Athletics to win the best-of-five series. Derek Lowe returned to his former relief pitching role to save Game 5, a 4–3 victory. The team then faced the Yankees in the 2003 American League Championship Series. In Game 7, Boston led 5–2 in the eighth inning, but Pedro Martínez allowed three runs to tie the game. The Red Sox could not score off Mariano Rivera over the last three innings and eventually lost the game 6–5 when Yankee third baseman Aaron Boone hit a solo home run off Tim Wakefield. Some placed the blame for the loss on manager Grady Little for failing to remove starting pitcher Martínez in the 8th inning after some observers believe he began to show signs of tiring. Others credited Little with the team's successful season and a dramatic come-from-behind victory in the ALDS. Nevertheless, Boston's management did not renew Little's contract and hired former Philadelphia Phillies manager Terry Francona.
