Tom McNamara must have a big smile on his face.

The Mariners’ amateur scouting director selected the right side of the North Carolina infield — first baseman Dustin Ackley and second baseman Kyle Seager — with two of his first four Draft selections last week and both had big days today at the College World Series in Omaha.

Ackley went 5-for-6 witha double and three RBIs and Seager was 2-for-4 with a home run in the Tar Heels’ 11-4 victory over Southern Mississippi in an elimination game.

Ackley, the Mariners’ first-round pick and the second player chosen in the First-Year Player Draft, needed a hit in his final at-bat to tie a CWS record for most hits in a game. He lined out to left field.

Dustin Ackley went 5-for-6 in UNC’s win today over Southern Miss, fellow Mariners draftee Kyle Seager was 2-for-4 with a homer in the win.

“I’ve been impressed,” manager Don Wakamatsu said of Ackley. “I saw couple of the highlight hits and even before the Draft I saw his tapes. What probably impressed me more than anything is he attacks. He gets into a hitting position and ready to hit and his ability to hit to all fields, but even more so with his interviews. He’s a pretty mature, sharp kid.”

Ackley now has 27 hits in 14 CWS games with at least one game remaining. The left-handed-batting first baseman has at least one hit in 21 consecutive tournament games since 2007, hit a third-inning single to break the record of 24 career hits by Stanford’s Sam Fuld (2001-03).
