Rox add lefty bat in 11th round with outfielder Dwyer

The Rockies picked up their fifth left-handed bat of the 2013 First-Year Player Draft when they selected Florida Gulf Coast left fielder Sean Dwyer with their 11th-round pick.

Dwyer was a well-regarded prospect coming out of high school in 2010, and was drafted in the 15th round by the Padres. He chose to attend Florida Gulf Coast instead and has improved his production each year.

2013 Draft Central

As a junior in 2013, Dwyer drove in 46 runs -- tied for the team lead -- while hitting .332 with six home runs and scoring 44 runs. He also led the Eagles with a .424 on-base percentage and a .512 slugging percentage.

Dwyer has a good approach at the plate, and his raw power is starting to show up in games. He has average speed, but uses it aggressively on the basepaths.

Dwyer played first base and left field in college. He profiles best as a corner outfielder, where he is a capable defender with an adequate arm. He did not commit a single error in 57 starts this year.

Manager Weiss' son drafted in 22nd round by Rox

DENVER -- Brody Weiss has already played on the Coors Field diamond twice, taking part in the Rockies Futures game each of the past two years. But his next appearance in Denver might be a bit different, as the Rockies, the club his father, Walt Weiss, manages drafted him in the 22nd round of the 2013 First-Year Player Draft.

Brody, who plays shortstop like his father did, has committed to play for University of California Santa Barbara, and it would be a major surprise if he signed with the Rockies. As a senior in high school, Brody hit .371 with 26 hits and drove in 23 runs as a senior for Aurora's Regis Jesuit High School (Col.).

"He got a few calls [from Major League teams]," said Weiss, a rookie manager. "The Rockies knew him best, because he's been running around here. He was down there all spring. They got to see him up close and personal. It's exciting. … I guess I'll have to negotiate with the Rockies the next couple weeks."

Walt played 14 years in the big leagues with the A's, Marlins, Rockies and Braves, winning Rookie of the Year in 1988 and making the All-Star team in 1998. He was a first-round pick (11th overall) by Oakland in the 1985 Draft.

But the Rockies manager won't be in the negotiating room talking numbers with the executives that he works with regularly.

"That's his mom. I'm not negotiating with [Rockies assistant general manager Bill] Geivett," Weiss joked.

Rox select Sooners lefty Waltrip in Round 12

He may not carry a pedigree equal to that of third overall pick Jonathan Gray, but the Rockies took another pitcher from Oklahoma in the 12th round of the First-Year Player Draft when they selected southpaw Billy Waltrip.

Waltrip began the year as a starter, but quickly moved to the bullpen, where he will likely stay at the professional level. His fastball can climb into the low-90s, but usually hangs in the high-80s. The lefty complements that fastball with a slider that allows him to pile up strikeouts.

Waltrip struggled with command as a junior, likely a product of his mechanical delivery, finishing with a 5.15 ERA and a 2-3 record in 20 appearances. He also struck out 45.

If the left-hander can regain control, he could be a solid bullpen piece for Colorado down the road.

Before joining Gray at Oklahoma this year, Waltrip played two years at Seminole State College in Florida, finishing 7-2 with a 1.60 ERA in his final year of junior college ball. The Orioles selected Waltrip out of Seminole State in the 12th round of the 2012 First-Year Player Draft, but he elected to delay the big leagues for the chance to play Big 12 baseball.

Infielder Benjamin goes to Rockies in Round 13

The Rockies spent their 13th-round pick on Arizona State third baseman Michael Benjamin, who was one of the Sun Devils' most trusted bats in 2013.

The right-handed Benjamin showed he could hit for power and average, hitting .335, driving in 47 runs and belting eight home runs. He was the lone player in the Pac-12 to rank in the top four in the conference in batting average, slugging percentage, runs, hits and homers.

Though Benjamin says he is a natural shortstop, he primarily played third base for the Sun Devils. However, with limited arm strength, he may be best suited for shortstop or second base in the pros.

An all-region quarterback in high school, he had enough pop in his bat and athleticism for the Rockies to draft him out of high school in the 45th round of the 2010 First-Year Player Draft.

Benjamin's junior season ended Monday when Arizona State lost to Cal State Fullerton in the NCAA Regionals.

Rox go back to South Alabama, draft Stamey

Colorado grabbed another bullpen arm in the 14th round of the First-Year Player Draft when it selected reliever Dylan Stamey from South Alabama.

Stamey -- a teammate of the Rockies' fourth-round pick, outfielder Jordan Patterson -- appeared on the radar of Major League scouts after an impressive junior campaign. In 24 appearances, he carried a 2.17 ERA and picked up four saves. He pitched 37 1/3 innings and struck out 62, an average of more than 1.5 strikeouts per inning.

With a sturdy 6-foot-2, 185-pound frame, he could develop into a reliable power pitcher out of the bullpen. Stamey also has the endurance to last multiple innings, especially valuable at a hitter-friendly park like Coors Field, where starters sometimes are hit hard and out after just a few innings.

Stamey, 21, came to South Alabama after two years at Faulkner State (Ala.) Community College and was named to the first-team Southern League. The right-hander had a 2.27 ERA in 35 2/3 innings and collected eight saves, finishing with a 4-1 record in 2012.

Rockies draft promising hurler Beck in Round 15

In the 15th round of the First-Year Player Draft, the Rockies grabbed John Beck, a right-hander who has shown promise at the University of Texas-Arlington, but recently endured a tumultuous junior year.

Beck has served as both a starter and reliever with the Mavericks, making six starts and 18 relief appearances this year. He struggled in 2013 with a 5.11 ERA and a 1-6 record while surrendering five home runs. He was much more effective as a sophomore, however, finishing with a 3-1 record and a 3.71 ERA.

Beck's fastball hangs between the high 80s and low 90s, but he has control issues that might explain the spike in his ERA this year. However, when he keeps his fastball down, it can lead to ground balls, always a plus when pitching at Coors Field.

The right-hander also throws a curveball -- potentially his best pitch -- that sits in the high-70s and usually has better command than his fastball.

At 21, Beck still time to develop a more consistent fastball and learn when to work in his offspeed pitches, which would turn him into an effective bullpen arm. At 6-foot-2, 195 pounds, the physical tools are there and he should improve under the guidance of professional coaches.
