CLEARWATER, Fla. — Jake Arrieta put on a red No. 49 Philadelphia Phillies jersey for the first time and sent a message to his new teammates and fans.

"We're going to promise a fight," Arrieta said Tuesday, a day after the ace righty finalized a $75 million, three-year contract that could be worth up to $135 million over five seasons. "We're going to have conviction and we're going to fight and we're going to win."

The Phillies haven't had a winning season since 2011, when they won their fifth straight NL East title. But the addition of Arrieta signals the end of a long, arduous rebuilding process.

Arrieta is confident a team that won only 66 games last year is poised to contend under first-year manager Gabe Kapler. The Phillies spent big in free agency, signing slugger Carlos Santana and relievers Tommy Hunter and Pat Neshek. They have a solid core of young hitters and their rotation could be formidable with Aaron Nola and Arrieta at the top.

Arrieta joined the Chicago Cubs in a trade from Baltimore in 2013 during a 66-96 season. The Cubs won 73 games in 2014 and were considered a year or two away from contention when Joe Maddon took over as manager in 2015.

They won 97 games and reached the NL championship series that year with Arrieta leading the way. He was 22-6 with a 1.77 ERA and earned the NL Cy Young Award.

The Cubs won the World Series the following season, ending a 108-year championship drought. Arrieta was 2-0 in the seven-game series against Cleveland.

"I'm here to not only lead by example but to help the guys take that next step," Arrieta said.
