Walker (1-1) earned the win Friday by holding the A's scoreless and striking out eight across seven innings. He allowed one hit and a pair of walks.
Walker retired his first eight batters before issuing a walk to Tony Kemp in the third inning. The only hit he gave up was a leadoff double to Ramon Laureano in the fourth. It was a long awaited successful outing for the 27-year-old, who underwent Tommy John surgery in 2018. Walker will look to stay in the win column with a favorable matchup against the Angels on Thursday.
