Ortiz excused for daughter's graduation

BOSTON -- David Ortiz is absent from Saturday's afternoon game against the Orioles while he returns from the Dominican Republic, where his daughter Jessica is graduating from high school. Farrell said Ortiz is expected to be back in the lineup for Game 2 of Saturday's day/night split doubleheader.

In his absence, A.J. Pierzynski slides into the designated hitter spot and No. 5 in the batting order. Brock Holt leads off, followed by Daniel Nava at No. 2, Dustin Pedroia third and Mike Napoli cleanup.

"He was gonna miss yesterday's game, but it just happens that it turns into the first game of today," Farrell said of Ortiz. "I fully expect him to be in the lineup tonight."

Meanwhile, left-hander Tom Layne was called up from Triple-A Pawtucket and will be the 26th player on the roster added for Game 2 tonight, giving the Sox eight arms out of the bullpen.

Layne, a 2007 draft pick of the Diamondbacks, signed a minor league deal with the Red Sox last November. The 29-year-old has been making a strong case with the PawSox as of late. In 10 relief appearances in June, Layne posted an ERA of 0.84 with six saves, striking out 13 batters in 10 2/3 innings and holding opposing batters to a .143 average.

"He's continued what he had in spring training, and that has been very successful against left-handers," Farrell said. "He's had decent ability to get good right-handed hitters out, so he's not solely a situational type of lefty reliever, but the performance has been very consistent."
