"The Mariners signed right-hander Carter Capps, their third-round pick in the 2011 draft, and assigned him to Class A Clinton. The team also signed catcher Luke Guarnaccia, their 19th-round pick, and outfielder Cory Scammell, their 35th-round selection.

Capps, 21, went 14-1 with a 1.75 ERA in 20 games, including 15 starts, last season for Mount Olive College. He struck out 129 and walked just 18 in 118 innings. He holds the NCAA Division 2 record of 24 consecutive wins. In 16 games with the Harwich Mariners in the Cape Cod League he went 4-1 with a 0.60 ERA, notching 34 strikeouts and walking two in 30 innings.

"Carter is a big, physical kid with a power arm potential," director of scouting Tom McNamara said in a news release. "He had a great college season as a starter and continued his success in the Cape Cod League. Bottom line is, he is a strike thrower with tremendous potential.""
