"I don't feel like I have to prove myself," Bastardo said. "I feel confidence in myself and what I need to do. Just do it. Just get people out."
Bastardo posted a 2.32 ERA in 48 games last season before the suspension. Manager Ryne Sandberg said he expects Bastardo to play "a big part in the bullpen." He will earn $2 million in 2014.
"He's been one of the best lefthanded pitchers against lefthanded hitters in baseball," Sandberg said. "He has a track record of that. I look forward to more of that."
Bastardo said he returned to the Dominican Republic during the suspension and used the time off to recharge. He was impressive during 14 innings of winter ball, with a 1.93 ERA and 24 strikeouts. That, he said, has him ready after the embarrassment of 2013.
"I made a mistake," Bastardo said, "and I paid the price."
The Phillies signed Chad Gaudin last month to add much-needed depth to a thin pitching staff. Their investment was short-lived; Gaudin failed his physical Wednesday and was released Thursday.
Gaudin, 30, signed a minor-league deal with a decent shot of making the club this spring. Amaro liked Gaudin's versatility, specifically his ability to serve as a swing man and start at a moment's notice. Gaudin started 12 games for San Francisco in 2013 and posted a 3.03 ERA in 30 appearances overall.
"It hurts," Amaro said. "Obviously, the roles he can fill as a long guy, a guy who can sit for 10 days and not pitch and then pitch as a starter, all of those things you like to have a veteran guy to be able to do. We have to find out if that guy is in our camp."
Many of the team's position players were in camp Thursday, well ahead of Monday's mandatory report date. Ryan Howard, Chase Utley, Ben Revere, Cody Asche, Darin Ruf, and Kevin Frandsen took batting practice and some fielding drills.
