The Last Chance Prospect Camp at Hartnell College in Salinas, Calif., gave players an opportunity to be seen by colleges and pro scouts. The idea was to give these players a chance to play at the next level.

Here are the standout players of the day:

Eric Nielsen out of Dublin (Calif.) High School sat comfortably between 90-91 mph with his fastball and had the top velocity on the day. With a 6-foot-8, 235-pound frame, he threw out of a three-quarter slot and kept the ball effectively down in the zone. With his size, velocity and pure stuff, he was the most impressive prospect at the pro level at the event.

Andrew O’Brien out of Corona (Calif.) High was one of the many underclassmen in the event. Graduating in the 2013 class, O’Brien had solid stuff with an 86-88 mph fastball and 70-73 mph curveball. He is list at 6-foot-2, 178 pounds and has a strong GPA of 3.6.

Tom Petersen of St. Francis (Mountain View, Calif.) was one of the more athletic players in attendance. He stood on the mound with an intimidating presence and with that he brought one of the heavier fastballs of the event. With a spread-armed delivery he brought his fastball at 87-88 mph. His delivery brought great deception that allowed his 70 mph slider to be a swing-and-miss pitch.

Mike Petersen out St. Francis was one of the more athletic players in attendance. Does that sounds familiar? It might ring a bell because Mike is the twin brother of the aforementioned Tom. The only thing that separated these twins on the mound was that Mike came in with the second-best velocity of the day. His fastball sat at 89-90 mph that set up his 72 mph changeup, which, like his brother's slider, was a swing-and-miss pitch.

Matt Krook is a well-known pitching prospect out of St. Ignatius (San Francisco). The left-hander recently attended the Arizona Fall Classic in mid-October and had a solid showing, throwing an 87-88 mph fastball. He is a good-bodied player with an athletic 6-foot-3, 190-pound frame. His off-speed stuff consists of a 78-80 mph changeup and a 77 mph curveball. Being a 2013 graduate, you will most likely be hearing about Krook around the summer showcase circuit after this spring season.

Dakota Mills out of Dulles (Sugar Land, Texas) was one of the few out-of-state players in attendance. Listed at 6-foot-2, 190 pounds, Mills had a very athletic build and looks like he will fill in more in the years to come. Offering a three-pitch mix, Mills came in with an average fastball that sat at 84-87 mph, a changeup that faded in between 74-71 mph and a solid slider at 73 mph. What separated Mills from the rest of the pack was that he threw all three of his pitches for strikes and located them well.

One of the more promising prospects was young 2014 graduate Matt Trask. Hailing from Davis (Calif.) High, Trask has a smooth delivery, good fundamentals for a sophomore, and already good velocity. Listed at 6-foot-1, 185 pounds, he still has a ton of growing to do. Built with wide shoulders and a V-shaped frame, his present velocity is 84-86 and has been seen up to 88 mph. Trask looks like a good bet to be hitting in the 90s once his time comes around to start thinking about where is he going to further his education.
