A's rely on Luis Medina as bullpen struggles against Red Sox

The Oakland Athletics' bullpen faced challenges in a recent four-game series against the Boston Red Sox, allowing eight runs in 15 innings for a 4.80 ERA. Right-hander Luis Medina, tasked with a one-run lead in the eighth inning, surrendered back-to-back homers to Wilyer Abreu and Willson Contreras, leading to a loss. Despite the setback, A's manager Mark Kotsay emphasized the importance of executing pitches with conviction for Medina's growth. Mason Barnett, making his first start of the season, impressed by going five innings with three earned runs and could earn a spot in the rotation as J.T. Ginn is set to return soon.
