Gallen (1-7) allowed four earned runs on eight hits and three walks while striking out five across five innings, taking the loss to the Padres on Sunday.
All of Gallen's runs allowed came via the long ball, including two solo home runs by Fernando Tatis. Gallen has struggled with preventing homers, surrendering eight over his last five starts. The 25-year-old has a 5.03 ERA, nearly double the ERA of his previous two seasons. His only win this year came on April 25. However, he is still consistently striking opponents out at a 10.7 K/9 rate through 73.1 innings this season.
