WASHINGTON (AP) — David Segui remembered “darts” but not dates.

The former major leaguer testified for the prosecution Thursday in the Roger Clemens perjury trial, and he would have made a much better witness if he kept a better mental calendar. As it was, Segui was able to recall one specific moment that helped the government’s case: a telephone conversation he says he had with Clemens’ strength coach 11 years ago.

“He mentioned that he had kept darts to get his wife off his back,” Segui said.

With those words, Segui echoed the testimony of the six-week-old trial’s key witness. Brian McNamee told the jury last week that he saved a needle and other materials from an alleged steroids injection of Clemens in 2001. McNamee testified he was trying to allay his wife’s fears he would take all the blame if the drug use was discovered.

“He mentioned that the relationship between Brian and Roger had put stress on his married life. … Coming and going … leaving at the drop of a hat to go train,” said Segui, recalling other parts of the conversation.

Segui, who has acknowledged using performance-enhancing drugs during his 15-year baseball career with seven teams, wasn’t allowed to say that “darts” means “needles.” The judge ruled that the jurors will have to make that assumption themselves — unless McNamee were to return to the stand to explain.
