Mateo went 1-for-3 with a three-run home run in Tuesday's 9-3 win over the Cubs.
Mateo's second-inning blast would be all the offense the Orioles needed, giving them a 5-1 lead at the time. He had gone 0-for-13 in his first five games in June prior to the long ball Tuesday. The shortstop is up to a .210/.240/.352 slash line with four homers, 15 RBI, 15 runs scored and 13 stolen bases through 51 contests.
