PHOENIX (Interstat) — The Arizona Diamondbacks, winners of eight of their last 10, welcome the Oakland Athletics to Chase Field on Tuesday night for the second game of a three-game series. Arizona (51-48) sits above .500 and looks to build on its recent surge. Oakland (42-57) is struggling, having lost seven of its last 10. Right-hander Jack Perkins (2-5) is the scheduled starter for the Athletics. Perkins has been inconsistent this season and will aim to give Oakland length after a taxing series against Washington. Players to watch Athletics left-handed pitcher Jacob Lopez has been used in a variety of roles. In his most recent outing Sunday against the Nationals, he threw 4 1/3 innings, allowing two earned runs on two hits with six strikeouts. He struggled in his previous two appearances, including a 1 2/3-inning scoreless stint July 10 and a three-inning outing July 7 in Detroit in which he allowed four earned runs on five hits. Diamondbacks shortstop Geraldo Perdomo has been a spark atop the lineup. Perdomo is 3 for 12 in his last three games, including a home run and two RBIs Sunday in a 8-7, 10-inning win over St. Louis. Over his last 10 games, he has two home runs, four RBIs and a .300 batting average.
