WEST SACRAMENTO, Calif. (Interstat) — The Miami Marlins and Oakland Athletics open a two-game series Saturday at Sutter Health Park, with first pitch set for 7:07 p.m. on Independence Day. Miami (46-42) enters the game as a -1.5 favorite on the run line, according to Interstat’s game simulator, which projects a 5-3 Marlins victory. The over/under is 10.5 runs. The Athletics (41-46) will look to build on a 7-1 win over the Los Angeles Dodgers on Wednesday, while the Marlins aim to snap a two-game losing streak after being outscored 20-7 in Denver. Players to watch: Otto Lopez, Marlins shortstop: The 27-year-old is batting .368 (7-for-19) over his past five games, including a 3-for-5 performance Thursday against the Rockies. He has two home runs and three RBIs in his last four contests. Lopez is hitting .310 in June and July combined and has been a steady presence atop Miami’s lineup. J.T. Ginn, Athletics pitcher: The right-hander is expected to start Saturday after earning a win July 1 with six innings of three-hit, one-run ball against the Dodgers. Ginn (4-3, 3.86 ERA) has allowed three earned runs or fewer in four of his last five starts, striking out 22 over 29 innings in that span. Series context: Friday’s series opener was postponed — no score was recorded — which means the teams will play a traditional doubleheader or a single makeup date later in the season. Saturday’s game is the first of two scheduled contests between the clubs this weekend. Recent results: Miami lost 14-4 to Colorado on Thursday, with Lopez going 3-for-5. The Marlins have dropped consecutive games for the first time since June 28-29. Oakland beat the Dodgers 7-1 on Wednesday behind Ginn’s strong start and a two-RBI home run from catcher Jonah Heim. The Athletics have won three of their last four games. Looking ahead: Following Saturday’s game, the Marlins conclude their road trip Sunday against the Athletics before returning home for a six-game homestand against Seattle and Cleveland starting Tuesday. The Athletics travel to Detroit for a three-game series beginning Tuesday.
