• On Saturday, 40 of the best high school baseball players in the country will take part in the 2014 Under Armour All-America Baseball Game at Wrigley Field, including two-sport star Kyler Murray of Allen, Texas.
Murray is the first to be selected for both the Under Armour All-America Baseball and Under Armour All-America Football games. He is best known as the top dual-threat quarterback in the country, and he has led Allen High School to two straight Texas 5A state titles.
Saturday's game will be played at 6:05 p.m. CT, and this will be the first time the annual summer showcase will be played under the lights at Wrigley. Since the game's inception in 2008, 185 of the 208 eligible players from the Under Armour All-America Baseball Game were selected in the First-Year Player Draft, including 51 first-round picks.
• On Tuesday night, in his first Minor League rehab start, left-hander Felix Doubront threw 80 pitches over four-plus innings for Triple-A Iowa in Des Moines against Las Vegas. Doubront, who has been on the disabled list since July 31 with a strained left calf, gave up four runs on four hits and two walks while striking out seven. The Cubs acquired Doubront from the Red Sox on July 30 for a player to be named.
• Outfielder Justin Ruggiano left Tuesday's game because of leg fatigue, but Renteria said the situation is not serious. Shortstop Starlin Castro stayed in the game despite aggravating his left knee, which he twisted running to first base on Monday.
