Vladimir Guerrero Jr. homered in both games of a doubleheader, including a solo shot to center in the nightcap that helped the Toronto Blue Jays earn a split with an 8-4 victory over the Baltimore Orioles. Guerrero went 7 for 10 in the doubleheader with five RBIs. In Game 2 Monday night, he had a homer, three doubles and three RBIs. Baltimore made three errors in the second game, leading to three unearned runs. In the opener, Zach Eflin turned in a gritty pitching performance in his Orioles debut, Anthony Santander hit his 30th home run and Baltimore cruised to an 11-5 victory. But the struggling Orioles never led in the second game and now have lost 11 of 17.
