AROUND THE HORN

■ Cardinals: Adam Wainwright threw a three-hit shutout as the Cardinals snapped the Marlins’ four-game winning streak 5-0. Wainwright (9-5) struck out five in his 10th career shutout and didn’t allow a hit until Adeiny Hechavarria doubled to open the sixth. Wainwright is 3-0 in three starts this month, allowing one run in 22 innings. Jhonny Peralta homered and Stephen Piscotty had two RBIs. ■ Nationals: Tanner Roark pitched eight innings of five-hit ball and had an RBI single in a 6-0 victory over the Pirates. Anthony Rendon homered and drove in two, and Stephen Drew had three doubles and an RBI as the Nats won their fifth straight. ■ Mariners: Hisashi Iwakuma limited the Astros to two hits in seven innings and Robinson Cano drove in the only run in a 1-0 victory. Iwakuma (10-6) became the first Mariners pitcher to reach double-digit wins. He struck out eight and walked one. ... RHP Felix Hernandez, out nearly two months with a strained calf, will pitch Wednesday against the White Sox. ■ Orioles: Chris Tillman gave up one run on four hits in seven innings and became the AL’s second 13-game winner in a 2-1 victory over the Rays. J.J. Hardy hit a two-run homer. Zach Britton struck out two in the ninth for his 29th save, sealing the Orioles’ fourth straight victory. ■ Athletics: Khris Davis homered twice, Ryon Healy hit his first and Sonny Gray won for the first time in nearly three months in a 5-4 victory over the Blue Jays. Healy’s three-run shot off R.A. Dickey was his first majorleague hit. Gray allowed three runs in six innings. ■ MLB: MLB executive Joe Torre sent a memo to managers, warning them to stop arguing balls and strikes. “The prevalence of manager ejections simply cannot continue,” Torre said. Managers are increasingly relying on technology from the clubhouse to argue from the dugout. Managers or coaches ejected for arguing balls and strikes “will be disciplined, including at least a fine,” he said.
