Smoak has been on the prospect radar for a long time. As a high school player in South Carolina, he was one of the top hitters available in the 2005 prep draft class. He ranked 95th on Baseball America's Top 200 draft prospects that year but fell to the 16th round because of a strong commitment to South Carolina, and wound up turning down a reported $850,000 signing bonus from the Athletics to join the Gamecocks. While he had three strong seasons in Columbia, the Gamecocks never reached the College World Series with Smoak in the lineup.

He ranked eighth in Baseball America's Top 200 draft prospects list but fell to No. 11 in the draft that year, behind fellow first basemen Eric Hosmer (Royals) and Yonder Alonso (Reds) and seven spots ahead of Ike Davis (Mets). Smoak was compared to Mark Grace out of high school but showed more power than that in college and in pro ball.

Smoak is an average defender, and the Mariners are betting on his bat. However, his power hasn't been in evidence at upper levels, particularly from the right side of the plate. He slugged just .363 at Triple-A Oklahoma City last season in 197 at-bats. This season, as the Rangers' everyday first baseman, he was hitting just .139/.207/.266 in 79 at-bats as a righthanded hitter, while hitting a more respectable .244/.367/.397 from the left side.

One pro scout contacted by Baseball America said a hitch in Smoak's swing was upsetting his timing, keeping him from maximizing his raw power, and as a result, his overall athleticism was beginning to be questioned.

The best prospect in the deal is Beavan, the towering righthander taken 17th overall in the 2007 draft, who must be bummed to be traded from his hometown club. He's in the midst of an outstanding season, and scouts consider him a future No. 4 starter and innings eater. While he no longer throws in the mid-90s as he did in high school, Beavan thrived with Frisco by commanding his 88-91 mph fastball and having a good feel for his changeup and slider. He had just 12 walks in 110 innings in Double-A and had earned a recent promotion to Triple-A.

"He can really pitch," one pro scout with an American League organization said earlier this week. "He doesn't need to throw hard to be effective. He has very good control, and it takes hitters one or two times through the order before they even start to get a feel for what he's doing. He's probably not an ace, but he's got average stuff with command. That's a fourth-starter profile."

An aggressive, offensive-minded second baseman, Lawson also has played some left field and profiles more as a utility player than as a regular. He's a grinder with some pop.
