Philadelphia at San Diego

Philadelphia owns a one-game lead over Atlanta in the National League East and comes off a 5-1 victory yesterday over the punchless Padres. Phillies righty Jake Arrieta (3.11 ERA) is throwing great and is unbeaten in seven starts. He is 4-0 with a 2.28 ERA since the beginning of July and has yielded fewer than three runs six times over that span. San Diego is 21-37 at home and on a 16-35 run, including a 5-16 run at home. The offense is #26 in runs scored and #29 in on-base percentage. Padres starter Joey Lucchesi has allowed 19 hits and 13 runs his last four starts (19 innings), so back the first-place visitors. Play Philadelphia.
