SEEKING A WIN

He is still seeking his first win since Sept. 29. 2013.The 2013 AL All-Star made just two starts, both losses, in April 2014 before having surgery. Moore will be opposed by Houston rookie Lance McCullers (4-2, 2.16 ERA), who attended high school in Tampa, Fla., and will be pitching against the Rays for the first time.
CROSSTOWN WRAPUP
Jake Arrieta (9-5, 2.80 ERA) goes for his 10th win as the Chicago Cubs wrap up their weekend series against Jose Quintana (4-8, 3.69) and the crosstown White Sox at Wrigley Field.
SEEING THE FUTURE
Reds greats Tony Perez and Ken Griffey Jr. will manage the Futures All-Star Game, with some of baseball's up-and-comers taking their swings at homer-friendly Great American Ball Park in Cincinnati. The game will kick off the All-Star festivities, with the Home Run Derby set for Monday night and the major league All-Star Game on Tuesday night.
