DETROIT (AP) - Alex Avila hit a tiebreaking grand slam in the sixth inning off Stephen Strasburg and the Detroit Tigers beat the Washington Nationals 5-1 Tuesday night. Anibal Sanchez gave up one run, five hits and two walks over seven innings for Detroit. Jose Veras, a day after being acquired from Houston, was perfect in the eighth in his Tigers debut. Joaquin Benoit, who will keep his job as the team's closer, gave up one hit in the ninth inning. Strasburg allowed five runs, six hits and three walks while striking out seven over seven innings. Strasburg is winless in his last four starts and has given up at least four earned runs in three of his last five outings.
