MOORESVILLE, N.C. -- Team Penske has overhauled the crew chief assignments for all three of its Cup Series teams.
Keselowski and Wolfe had been paired since the 2010 Xfinity season. They were paired in Cup in 2011 and won 21 races since then. Their split leaves 2014 champion Kevin Harvick and Rodney Childers as the longest active paired driver/crew chief combo (since 2014) in the Cup Series.
Logano and Gordon had worked together since 2013, winning 21 races and the Cup title. Blaney had Bullins as his crew chief for all 162 career Cup starts and three wins since 2014.
"As we do after the completion of each season, we evaluated what we can do to better achieve our goals and we felt it was time to make these changes to better position us to reach our potential," team owner Roger Penske said. "We are fortunate that we have three very strong leaders in Paul, Todd and Jeremy, who work with experienced and talented crews. Pairing each of these winning teams with different drivers and cars should provide new energy and a fresh approach for the 2020 season."
