PHOENIX (Interstat) — The San Diego Padres, holding the National League’s best record at 17-8, visit the Arizona Diamondbacks (14-11) at Chase Field on Saturday at [time TBD]. Right-hander Germán Márquez (2-1) is scheduled to start for San Diego, while Arizona counters with right-hander Michael Soroka. Márquez will look to build on the Padres’ momentum after a 10-8 victory Thursday at Colorado. San Diego has won four of its last five games and eight of its last 10. First baseman Gavin Sheets has been a key contributor for San Diego. After a 1-for-2 outing Thursday that included a home run and three RBIs, Sheets has hit safely in three of his last four starts. Over his past 10 games, he is batting .250 with one homer and three RBIs. Soroka takes the mound for Arizona after allowing one earned run over five innings in a 4-1 loss to the Chicago White Sox on Thursday. In his previous four starts, the right-hander compiled a 2.57 ERA over 22 2/3 innings while striking out 24 batters. Arizona has lost four of its last six games. Despite Arizona being installed as a -1.5 run favorite, Interstat’s game simulator projects an 8-5 San Diego victory. Interstat’s ELO system gives the Padres a 52.20 percent probability of winning. The over/under for the contest is set at 15.5 runs. San Diego’s offense is averaging 5.8 runs per game this season. The Diamondbacks are averaging 5.1 runs. Following Saturday’s game, the teams meet again Sunday to close the two-game series. The Padres then return home for a three-game set against the Chicago Cubs beginning Monday. Arizona travels to Milwaukee for a three-game series starting Tuesday.
