Minnesota rookie Danny Santana is swinging a hot bat and attempts to torment Houston again on Sunday when the host Twins close a three-game set against the Astros. The 23-year-old Santana hit his first major-league homer Friday and had the best outing of his 21-game stint in the majors Saturday by going 4-for-5 with five RBIs in Minnesota's 8-0 victory. Saturday's loss snapped the Astros' six-game road winning streak.Santana's emergence comes at the same time the Twins are attempting to spruce up their offense by agreeing on a one-year contract with free agent Kendrys Morales, who hit 23 homers for Seattle last season. Morales will be primarily used as a designated hitter while occasionally spelling first baseman Joe Mauer. Houston outfielder George Springer has struck out in 12 of his 23 at-bats in June after earning American League Rookie of the Month honors for having 10 homers and 25 RBIs in May.TV: 2:10 p.m. ET, CSN Houston, FSN North (Minnesota)PITCHING MATCHUP: Astros RH Collin McHugh (4-3, 2.52 ERA) vs. Twins RH Samuel Deduno (2-3, 3.83)McHugh has won back-to-back starts, allowing seven hits over 12 shutout innings against the Kansas City Royals and Los Angeles Angels.
