Yordan Alvarez becomes the first Astros rookie to hit three home runs in a game. The 22-year-old slugger went 4-for-5 with a double and a walk to lead Houston to a 15-4 win over the Orioles. Alvarez's historic performance included home runs in three consecutive at-bats, capping off a 5-for-5 night with 10 total bases. The rookie outfielder's power display set a new Astros rookie record and marked the first three-homer game by a Houston player since Carlos Lee in 2007.
