The Phillies need Bastardo in October, beginning with Saturday's Game 1 of the National League division series against St. Louis, because the bullpen offers little stability beyond Ryan Madson. Brad Lidge has pitched strong recently, but has stranded an unsustainable 90 percent of runners. Mike Stutes rediscovered the life on his fastball at the end of the season, but his dependability remains a question.
Asked Friday which pitcher he would use in a tight eighth-inning situation, Charlie Manuel was brusque.
"I don't know, man," he said.
When the Phillies won the World Series in 2008, their bullpen - mostly the duo of Lidge and Madson - was the best in baseball. They counter that in 2011 with the best starting staff in the game. And Manuel will surely ride his Four Aces until the breaking point. But if Bastardo can reclaim his supremacy from earlier, the manager is presented with another option.
There is hope. Bastardo threw 12 pitches Tuesday in Atlanta that allowed everyone to smile. Brooks Conrad grounded out on an 85 m.p.h. slider. Matt Diaz flew out to center on a 94 m.p.h. fastball. Michael Bourn whiffed at another 94 m.p.h. heater and Bastardo had completed the elusive clean inning.
On Friday, he wondered if Baez had a part in it.
"He told me something I've been doing wrong," Bastardo said. "I've been thinking about it."
Fellow countryman Jose Contreras told Baez he thought it would be a good idea to contact Bastardo. Baez was hesitant to interfere, but reprised his role as mentor a week ago and texted the 25-year-old lefty.
"Are you tired?" Baez typed. "Are you fine?"
"My slider is not working right now," Bastardo responded.
So Baez started watching all the video he could find on Bastardo. He compared Bastardo's delivery at different points in the season. He took notes and relayed them to Bastardo.
"I saw him do a lot of things wrong with his mechanics," Baez said.
Baez, who posted a 5.81 ERA in two seasons as a Phillies reliever, pointed to Bastardo's hand and glove positioning before he began his motion. At first, his hands were slower than the rest of his body, and that forced him to rush at the most crucial moment. His slider was rendered useless.
"I remembered what he was doing before," Baez said. "Little things make him get in the right position."
Bastardo remains a shy figure in the Phillies clubhouse. With success, his confidence grew. But some teammates pointed to Baez's influence as a major factor in Bastardo's becoming comfortable with life as a major leaguer.
Now, Baez may have offered one final favor. Maybe all Bastardo needed was a familiar refrain from his mentor. Maybe it's all mental.
"He will be big for them in the playoffs," Baez said.
And he'll be watching from Miami with his two daughters, hoping his words play a small role in a championship for his former team.
