A switch-hitter whose 6-foot-3, 200-pound frame could cause him to outgrow his current position, Littlewood hit .538 and .531 in his final two prep seasons. His double in the 2008 Youth Pan-Am Games was one of the deciding hits in Team USA's 16-and-under squad's gold medal win against Mexico.
Round 3: Ryne Stanek, RHP, Blue Valley High School (Stilwell, Kan.)
Stanek posted a 0.85 regular-season ERA and helped lead his team to the Class 6-A state title this season, pitching a shutout and hitting two doubles in the quarterfinals. The long-armed Arkansas signee has reached 97 miles per hour on the radar gun but is more consistently in the high 80s and low 90s.
Round 4: James Paxton, LHP, No School
Paxton's 2009 season landed him a supplemental first round pick, but he couldn't agree to terms with the Blue Jays and returned to the University of Kentucky for his senior year. Baseball America considered him the top college pitcher for 2010 and a top-10 Draft selection, but a spat with the NCAA led to him leaving UK for independent league ball and his stock fell.
Round 5: Stephen Pryor, RHP, Tennessee Tech
A hard-throwing reliever, Pryor struck out a whopping 75 of 178 batters faced this season.
Round 6: Christian Carmichael, C, Mililani High School (Mililani Town, Hawaii)
Carmichael hit .410 with four homers and 20 RBIs this season.
Round 7: Maguire Wiswall, 1B, Boston College
After three seasons, Mickey ranks second in Boston College history with 37 home runs. He blasted 19 this season and was an All-Atlantic Coast Conference first-teamer.
Round 8: Jabari Blash, RF, Miami Dade College South
Athletic for his 6-foot-5, 218 pound frame, Blash turned down a ninth-round selection by the Rangers last year to return to Miami Dade. He hit .341 but was kicked off the team in April.
Round 9: Luke Taylor, RHP, Woodinville Senior High School (Woodinville, Wash.)
Taylor is a converted shortstop and signed to play at the University of Hawaii next year. He played for the same high school as current Mariner Matt Tuiasosopo, making him the first local selection by the club in 2010.
Round 10: Tyler Burgoon, RHP, University of Michigan
Burgoon tied a school record for saves this season with 10.
Round 11: Jon Keller, RHP, Xavier High School (Cedar Rapids, Iowa)
Keller was diagnosed with Type 1 diabetes as a high school freshman and takes between three and 10 insulin injections per day, but it hasn't slowed him. With a fastball in the mid 90s, he projects as a reliever.
Round 12: Stefen Romero, 3B, Oregon State University
Romero hit .326 this season as a junior and led the Beavers with 13 home runs.
Round 13: Jason Markovitz, LHP, Cal State University Long Beach

Round 14: Tyler Linehan, LHP, Sheldon High School (Sacramento, Calif.)
Linehan fanned 95 batters this season after striking out 93 and 70 the previous two seasons. He set a school record with 18 strikeouts in a game.
Round 15: Charles Kaalekahi, RHP, Campbell High School (Ewa Beach, Hawaii)
Round 16: Jordan Shipers, LHP, South Harrison High School (Bethany, Mo.)
Shipers' school didn't have a baseball team, so he honed his craft in wood-bat leagues. He threw a no-hitter in the 2009 Junior Sunbelt Showcase for Team Missouri.
Round 17: Danny Lopez, SS, University of Pittsburgh
Lopez hit .349 this season, the best of his career as a four-year starter at Pitt.
Round 18: William Kesler, RHP, University of New Mexico
At a squat 6-feet, 225 pounds, Kesler has already bounced back from Tommy John surgery and can hit in the low 90s.
Round 19: Frankie Christian, CF, Upland High School (Upland, Calif.)
Round 20: Matthew Bischoff, RHP, Purdue University
Bischoff is the first player in school history to earn all-Big 10 Conference honors in four seasons.
Round 21: Luke Guarnaccia, C, St. Thomas Aquinas High School (Ft. Lauderdale, Fla.)
Guarnaccia caught and pitched in high school.
Round 22: Stephen Landazuri, RHP, Carter High School (Rialto, Calif.)
In April, Landazuri's school squared off against Mariners first-round pick Taijuan Walker's Yucaipa High. Neither pitched, and Yucaipa won 16-3.
Round 23: Jandy Sena, RHP, Marion Military Institute
At 6-foot-6, 245 pounds, Sena is the biggest player in a Mariners Draft class that began with five straight players that stand at least 6-foot-3.
Round 24: Bennett Whitmore, LHP, Concordia University
Whitmore was the Mariners' 32nd-round pick last year, but he didn't sign and then left the University of Oregon for Concordia before his senior season. He led the team in starts, wins, innings and strikeouts, among other categories.

Zaragoza is signed to play at San Diego State University next season.

Anston started every game this season as the leadoff hitter, and he led the Eagles in doubles (21), triples (6) and steals (18) while finishing second in batting average (.324), on-base percentage (.409), runs (55) and hits (77).
Round 27: Nick Fleece, RHP, Texas A&M University
Fleece took to the hill after spending his freshman year as an outfielder. This season he was 1-2 with a 4.09 ERA and one save while making the first five starts of his career.
Round 28: Tim Griffin, RHP, Rollins College
Griffin finished sixth in the nation in wins this year with 11 and led the team with a 2.76 ERA and 94 strikeouts. He threw seven complete-games with three shutouts. His cousin, Shawn, played at the University of Tennessee and for the Kansas City Royals.
Round 29: Jonathan McGibbon, 1B, Lindenhurst High School (Lindenhurst, N.Y.)
McGibbon played receiver on his school's football team and signed a baseball scholarship to play at Clemson University.
Round 30: Derek Poppert, SS, University of San Francisco
Poppert hit .308 this season with 19 doubles and 30 RBIs, and he struck out just 16 times in 201 at-bats.
