Worth noting

• Fourteen pitchers threw their first live batting practices on Friday, including Scott Baker, Randy Wolf and Zach Miner, a trio of veteran non-roster invitees who are coming back from Tommy John surgeries in 2012.

"I thought the ball came out good for all three of them," said McClendon. "They're obviously a little rusty, but that's OK. They came through it good and it looked free and easy. That's what I was looking for. We're not looking for any kind of results, just free and easy."

• Two veteran relievers -- Fernando Rodney and Ramon Ramirez -- threw bullpen sessions instead of live BP. Rodney was just getting extra work before making his live debut, while Ramirez was a late arrival to camp due to visa problems getting out of the Dominican Republic.

• While most hitters continue taking limited swings in the early days of live BP, Michael Saunders ended his outing against Charlie Furbush with a blast over the right-field fence. Saunders and Furbush both threw their arms in the air as the ball cleared the wall, Saunders in jubilation and Furbush in mock indignation.

"Somebody had to give up the first one," Furbush said.

• Early observation on McClendon's first Mariners camp: Coaches work at a quick pace when doing drills with their position groups. And once everything is accomplished, they move on, even if ahead of the timed schedule.

"Having been a player, I know that when you start getting monotonous with drills, nobody pays attention," McClendon said. "My thought process is, let's have a camp that is precise, quick and to the point. Guys get it, they retain it and we move on. It keeps camp interesting and happy for guys. You want to have a good, upbeat, happy type of camp."
