Trey Mancini, picked in the eighth round by the Orioles, hit behind the highly touted Eric Jagielo in Notre Dame's lineup this season, giving the Fighting Irish a formidable one-two punch.

While Jagielo is the better all-around prospect, Mancini actually hit one point higher than his teammate, batting .389 in 2013. He also led Notre Dame with 54 RBIs and 138 total bases while striking out just 23 times in 229 at-bats.

Listed at 6-foot-5 and 205 pounds, Mancini is strong and creates good loft with his quick right-handed swing, leading to 28 career collegiate homers. Mancini needs to improve his pitch recognition to reach his potential as a hitter, and his value is tied to his bat.

Mancini is a capable first baseman, defending his position with a .990 fielding percentage this year.

With third-round pick, O's grab lefty Tarpley

Draft 2013: Orioles draft LHP Stephen Tarpley No. 98

BALTIMORE -- After drafting a trio of high-school players on Day 1 of the First-Year Player Draft, the Orioles picked five college players and three high schoolers on Friday's Day 2.

Scouting director Gary Rajsich said the Orioles didn't enter the Draft with a plan of selecting so many high-school players Thursday and Friday, but that's just the way it worked out.

"No, it's just coincidence," Rajsich said. "In any Draft, you have players targeted where you're comfortable taking them and where you think they fit. And with 29 other teams picking, they're not always available. ... We try to get the best value for that pick that we can and it seems like early in the Draft, it was in the younger players and in the later rounds today it was in the older players."

Among those choices were three left-handed pitchers, three catchers, a first baseman and a third baseman. The Orioles drafted four catchers with their first 11 selections.

"It's all about acquiring assets for your organization," Orioles manager Buck Showalter said. "Whether they play for you or somebody covets them enough to give you the player that might be a difference-maker on your club. It's all about acquiring assets."

The Orioles began their day by using their third-round pick to select left-hander Stephen Tarpley out of Scottsdale Community College in Arizona.

Once an eighth-round pick of the Indians in 2011, Tarpley instead initially honored his commitment to Southern California to start his college career. After just one season at USC, the Arizona native transferred closer to home to Scottsdale Community College, thus making him eligible for this year's Draft, in which the Orioles selected him at No. 98 overall.

"We think he's a left-hander with tremendous upside," Rajsich said. "We like him as a future starter that can really hold down a spot in our rotation. He's got a live, quick arm and a pretty good delivery that needs a few minor adjustments. But he's got a live, hard fastball, he throws a curve and a slider and he's got good feel for a changeup."

In his sophomore season at Scottsdale Community College, Tarpley went 3-2 with 15 starts and a two-inning bullpen appearance. He struck out 108 batters in 92 innings and walked 40.

As a freshman at USC, Tarpley went 5-3 with 3.22 ERA in 14 appearances, including 13 starts. Notably, he didn't give up a home run in 78 1/3 innings. He struck out 67 batters and walked 29.

The strong and athletic lefty can crank his fastball up to 94 mph with easy effort. Both Tarpley's curve and slider can be at least average, if not better. His changeup is behind the breaking stuff, but should also be a Major League average pitch for him.

Tarpley can throw strikes and has terrific mound presence with his 6-foot-2, 190-pound frame. It's that combination, especially from the left side, that led to Tarpley's selection in this year's Draft. The southpaw has an upside as a future member of a big league rotation.

Tarpley was the first of eight selections the Orioles made on Day 2, which included rounds 3-10.

Baltimore also selected Amherst High School (N.Y.) catcher Jonah Heim, Crestwood (Canada) left-hander Travis Seabrooke, Calvert Hall (Md.) catcher Alex Murphy, Youngstown State (Ohio) third baseman Drew Dosch, Notre Dame (Ind.) first baseman Trey Mancini, Dartmouth (N.H.) left-hander Mitch Horacek and Fresno State (Calif.) catcher Austin Wynns.

"I think we're building. We're trying to get younger and at the same time we're trying to get better," Rajsich said. "We're trying to always add pitching, because pitching is very important. At the same time, we're addressing the short- and long-term needs of our organization as far as getting guys quickly who can help at the Major League level and also developing the young guys for the future."

Day 3 of the Draft continues with Rounds 11-40 streamed live on MLB.com on Saturday, starting at 1 p.m. ET.

In the Pipeline
The Orioles have had their top picks rocket through the system in recent years, from Manny Machado to Dylan Bundy and, recently, Kevin Gausman.

With those players having contributed in the Majors at the age many prospects are still refining their game in the Minor Leagues, some analysts peg the Orioles' farm system as middle of the pack.

O's note Heim's upside, take him in fourth round

The Buffalo, N.Y., area isn't known to be a hotbed of baseball talent, but Jonah Heim is the second premium catching prospect in two years that area scouts have been fortunate enough to evaluate.

At 6-foot-3, 189 pounds, Heim is tall for a catcher, but he has plenty of upside that had scouts excited entering this year's MLB First-Year Player Draft, in which he went at pick No. 129 by the Orioles.

Despite his size, Heim -- out of Amherst Central High School -- has good pop at times, and still is fairly agile behind the plate.

Heim has a strong arm and, in time, has the potential to be at least an average defender. There are more questions surrounding his offensive ability, but he has some raw power and a good approach at the plate.

Heim is committed to play at Michigan State next year.

Canadian Seabrooke taken in fifth round by O's

Canada's crop of Draft talent this year isn't terribly deep, but Travis Seabrooke stands out among that pool as a lefty with a high ceiling, and the Orioles took a chance on him in the fifth round.

At 6-foot-5, 182 pounds, Seabrooke is athletic and very projectable.

His fastball will sit around 90 mph, but it has great downward plane and should see an uptick in velocity as he fills out. Seabrooke has also shown good feel for his curveball, which has the potential to be an above-average offering down the line. His changeup lags behind the other two offerings but could become average in the future as he learns to use it more.

Baltimore goes with Murphy's bat with sixth-round pick

Alex Murphy, Baltimore's sixth-round pick, was named the 2013 Gatorade Maryland Baseball Player of the Year and earned All-Metro as a senior. He was a team captain and four-year starter.

In his senior season, Calvert Hall won the Maryland Interscholastic Athletic Association "A" Conference championship. Murphy also won the championship his junior season with Calvert Hall, the school's second consecutive title and seventh in the past nine years.

Murphy won the home run derby at the Hard 9 Classic, where he beat out 31 other players from 15 teams around Utah and California.

He is committed to Wake Forest.

Plate approach attracts O's to seventh-rounder Dosch

Draft Report: Drew Dosch, College Third Baseman

Drew Dosch began last summer as a temporary fill-in in the Cape Cod League, but he wound up playing well enough to work his way onto the All-Star team as the starting designated hitter.

Dosch, a third baseman, played well this spring at Youngstown State, hitting .338 with a .434 on-base percentage and a .488 slugging percentage. He got on base more often but otherwise saw his numbers drop from his sophomore season, when he compiled a .353/.408/.527 line with eight homers and only 21 strikeouts in 224 at-bats.

The last Penguins player to get drafted before the 27th round was Justin Thomas, taken by the Mariners with the 119th overall pick in 2005.

Dosch has an advanced approach at the plate. The 20-year-old has decent power, but he barrels the ball well and has a smooth left-handed swing.

Dosch committed 15 errors in each of his last two seasons at Youngstown State and doesn't have great range, which may force him to move across the diamond to first base as a professional.

Dartmouth southpaw Horacek selected by O's

The Orioles took Dartmouth left-handed pitcher Mitch Horacek at No. 279 overall with their ninth round selection.

Horacek had a good season for the Big Green.

The left-hander went 6-2 this year in eight appearances, seven of which were starts. In 45 innings, he had a 2.20 ERA and 42 strikeouts with 10 walks. Opposing batters hit just .241 against him in 166 at-bats.

Horacek stands 6-foot-5, 210 pounds. He grew up in Highlands Ranch, Colo., and attended ThunderRidge High School.

O's get quite a catch with Wynns to close Day 2

To conclude Day 2 of the Draft, the Orioles used their 10th-round pick to select Fresno State catcher Austin Wynns.

Wynns, a senior, grew up in Poway, Calif., and attended Poway High School.

The 6-foot-2 backstop made the Western Athletic Conference All-Tournament Team in 2012. He also earned Academic All-WAC that year.

In high school, he won the California Interscholastic Federation championship in 2008 and '09.

Wynns batted .267 this season, finishing .286 overall in his four-year career at Fresno State, including a .326 batting average as a sophomore.

In 567 collegiate at-bats, Wynns had 40 doubles, two triples and five home runs.
