Senior guard Kassius Robertson scored 23 points as Missouri, playing without freshman phenom Michael Porter Jr., routed Wagner 99-55 on Monday in Columbia, Mo.

Porter, a projected NBA lottery pick, played only two minutes in Friday's 74-59 season-opening victory over Iowa State before leaving with a nagging left hip injury. The excitement surrounding the 6-foot-10 forward has led to a season sellout for Tigers home games.

Missouri freshman forward Jontay Porter, Michael's less-heralded brother, had 11 points, eight rebounds, four assists and two steals. Senior forward Jordan Barnett added 13 points for the Tigers (2-0), who shot 67.4 from the field and made 12 of 22 from 3-point range.

Sophomore guard Blake Francis scored 17 points for the Seahawks (1-1). Wagner shot 33.3 percent from the floor and was 6 of 20 from beyond the arc.

Jontay Porter was a big factor in Missouri's fast start as the Tigers led 54-21 at halftime.

Porter hustled in the corner to save a 3-point miss by Robertson from going out of bounds and passed back to Robertson, who drilled a 3 to make it 33-10. Porter provided a nifty assist on Terrence Phillips' bucket that capped a 15-1 run and made it 42-11.

Porter, who stands 6-11, had nine points, seven rebounds and four assists in the first half as Missouri torched Wagner for more points than it allowed in its 60-49 season-opening victory over NJIT on Saturday.

Robertson's 3-pointer made it 63-23 with 17:22 remaining before Wagner scored seven straight points, highlighted by a Francis 3-pointer. Robertson's fifth and final 3-pointer extended the lead to 74-34 with 10:07 to play.
