Orioles lineup (plus deal with first-round pick Cody Sedlock)

The Orioles have reached agreement with their first-round draft pick, University of Illinois right-hander Cody Sedlock, who will be introduced to the media later today at Camden Yards.

The lineup for tonight doesn't include shortstop J.J. Hardy. He was on the field taking ground balls, but he must not be coming off the disabled list.

Francisco Pena is behind the plate after Matt Wieters caught all three nights in Boston.

According to the Elias Sports Bureau, Tyler Wilson is the third Orioles rookie starting pitcher in the last 25 years with an outing of at least eight shutout innings and three hits or fewer, joining left-handers Chris Waters (2008) and Zach Britton (2011).

With Brian Matusz now in the Cubs organization, first baseman Chris Davis will serve as race ambassador for the seventh annual Casey Cares 5K Run/Walk on Saturday, Aug. 6 at Camden Yards.

"We thank the Orioles for again serving as an integral partner of Casey Cares this season," said Casey Baynes, executive director of the Casey Cares Foundation. "Last year, with the support of the Birds, Casey Cares was able to provide more than 19,000 activities to our community. The Orioles' ongoing commitment to the critically-ill children in our programs helps these kids have an unforgettable, once-in-a-lifetime experience."

Davis and his wife, Jill, a former nurse, have supported Casey Cares for several years. Davis has previously attended the organization's Extra Innings Event, where critically ill children and their families meet with Orioles players to learn the fundamentals of baseball. Davis will be attending the Extra Innings Event again this year.

The 3.1-mile run/one mile walk starts at 8 a.m. at Camden Yards and ends on the field. Participants will partake in a pre-race warm-up with the Oriole Bird, music and other entertainment, and will enjoy post-race refreshments. Top race winners will be announced in a pregame ceremony prior to the Aug. 16 game against the Red Sox.

Registration for the race is now open. Entry fees are $45 per person through Friday, Aug. 5, or $50 per person on race day (cash or check only). Children 8 and under can be registered for only $20. To register, visit www.orioles.com/caseycares.

The Mariners designated former Orioles pitcher Steve Johnson for assignment.

The Baltimore native was 1-0 with a 4.32 ERA in 16 relief appearances. His ERA was 2.87 before he allowed three runs without retiring a batter on June 12. He worked a scoreless inning two days later in his final outing.
