Cubs pitcher Jon Lester said a lawsuit alleging his agents for years have steered clients to providers of performance-enhancing drugs doesn’t change his relationship and trust with the ACES sports agency — and he scoffed at the suggestion the proceedings could affect him. “It doesn’t strain anything on my end,” said Lester, who learned about the lawsuit when one of his representatives called as Lester was on a golf course. “I’m sure they called all their clients and said, `Hey this is what’s going on,’ “ Lester said. “I’m like, `Hey, I’ve got to get a tee shot right here. I don’t really care.’ “ The lawsuit, first reported by Jon Heyman of Fanragsports.com, was filed last week in New York State Supreme Court by Juan Carlos Nunez, a former employee of ACES, one of the largest agencies representing baseball players.
