SANTA CLARA (AP) — Torrey Smith believes in his ability to turn a simple catch into a big gain, and he knows Colin Kaepernick has the strong arm to deliver the ball just where he likes it.

“He has a strong arm and I can run,” Smith said Wednesday when he formally joined the San Francisco 49ers. “That’s a good combination there.”

The free agent wide receiver finalized his new five-year contract with the Niners, filling a void left by Michael Crabtree’s expected departure and reuniting him with a couple of former teammates — Anquan Boldin and Vernon Davis.

Smith even played against Kaepernick in college, and has worked out with him in Miami — and plans to track down the quarterback in Arizona this spring for more joint workouts.

The deal includes $22 million in guaranteed money and could be worth as much as $40 million, a person with direct knowledge of the contract said, speaking on condition of anonymity because details weren’t announced. Smith had been scheduled for a physical early Wednesday, then the team announced the deal.

Former Ravens teammate Boldin helped recruit Smith to San Francisco, and believes they could be a dynamic twosome in the receiving corps.

Boldin’s pitch: “No. 1, the organization, it’s a first-class organization, something he was used to in Baltimore,” Boldin said. “And then just having the opportunity to win. I think we have the pieces in place to make that happen. (Because of) the guys we still have on the roster. Every year you’re going to have guys leave. But I think we have a bunch of guys that can step in and fill those roles.”

The two helped the Ravens beat the 49ers by three points in the Super Bowl at New Orleans following the 2012 season.

“I can definitely make the big play,” Smith said. “I can turn a simple play into a huge gain.”

Also Wednesday, running back Reggie Bush visited team headquarters and could be seen walking outside Levi’s Stadium with new head coach Jim Tomsula.

The 26-year-old Smith had 49 receptions for 767 yards and 11 touchdowns last season, his fourth year with the Ravens.

Smith spoke with departed running back Frank Gore, who gave him a positive scouting report about the franchise — one that finished 8-8 and replaced Jim Harbaugh with Tomsula. Five-time All Pro linebacker Patrick Willis retired Tuesday and others have left in recent days.

“I’m comfortable with what’s going on,” Smith said.

Smith, who made a formal farewell to Baltimore, played in college with Davis at Maryland. Now, he is working on his master’s in business administration at Miami.

He hopes to take some pressure off Boldin and Kaepernick.

“He’s a guy who can definitely help us win football games,” Boldin said. “I played with him for two years in Baltimore. It was good for me. He helped me out and we complemented each other as receivers.”
