OXFORD, Ohio -- Tim Schenke tipped in the go-ahead basket with nine-tenths of a second to play and Juby Johnson continued his scoring surge with 30 points, leading Miami of Ohio past Marshall 74-70 Saturday. The RedHawks (17-10, 12-6 Mid-American Conference) won on a last-second basket for the second straight game. Miami beat Kent State 59-57 Wednesday night when Danny Horace rebounded Johnson's missed jumper and scored on a putback as time expired. The Thundering Herd (11-16, 8-10) tied the score 70-all on LaVar Carter's three-point play with 15 seconds to play. Johnson's jumper with two seconds left was off the mark, but Schenke followed up to give the RedHawks the lead. Marshall quickly turned the ball over, and Johnson closed the scoring with two free throws. Johnson scored 31 against Kent State and has 88 points in his last three games. Marvin Black led Marshall with 18 points, Ronny Dawn added 14 and Mark Patton had 10. Miami erased a 39-31 deficit with a 21-8 run over nearly seven minutes of the second half. Johnson scored nine points and the RedHawks made four of their nine 3-pointers in the surge to lead 52-47 with 9:44 to play. The RedHawks finished 9-for-25 on 3s. Marshall went 7-for-9 beyond the arc and shot 51.1 percent overall. Josh Hausfeld added 15 points, Chet Mason scored 11 and Gene Seals had nine points and 10 rebounds for Miami.
