The Yankees’ heralded bullpen depth could be tested early. Andrew Miller broke his non-pitching wrist when struck on the right arm by a line drive in the seventh inning of New York’s 2-0 win over the Atlanta Braves on Wednesday. The left-hander threw his glove and walked into the Yankees’ dugout after pinch-hitter Willians Astudillo’s comebacker went off his arm, just above the wrist.
