With the 440th pick overall in round 15, Minnesota drafted left-hander Derrick Penilla out of Mount San Antonio College.

Penilla led the Mounties with 90 1/3 innings in 2013 as he went 6-3 on the season. He posted a 2.39 ERA with 96 strikeouts and 32 walks in 16 appearances -- 14 of which he started.

"He's got a good changeup and his fastball is anywhere from 87 to 91 [mph]," scouting director Deron Johnson said. "He's not a hard thrower, but he throws strikes and he's got a pretty breaking ball."

The 6-foot-2, 180-pound left-hander was the second lefty the Twins have picked up.

2013 Draft: MLB.com looks at the Twins' picks

With their 11th-round pick, No. 320 overall, the Twins selected high school shortstop Nelson Molina.

Molina, 18, is ranked as the No. 5 prospect from Puerto Rico by Baseball America.

The 6-foot-3, 175-pounder from Arecibo, P.R., bats left-handed. He has above-average speed and is steady defensively, possessing a good arm.

"He's got a nice body," scouting director Deron Johnson said. "We think he's a true shortstop and we think he's got a nice left-handed swing."

Pitt righty Mildren goes to Twins in Round 12

In the 12th round, No. 350 overall, Minnesota selected right-hander Ethan Mildren.

The junior out of Pittsburgh is the first Panther drafted by the Twins. In 2013 he pitched 114 2/3 innings for a 2.35 ERA. With a 10-3 record, the 6-foot-4, 230-pound righty went seven-plus innings in 13 of his 15 starts and struck out 76.

"He won't light up the gun -- he's 90-91 [mph] -- but he throws straight and we think he's a starter," scouting director Deron Johnson said.

He also earned first-team All Big East honors in 2013.

In Round 13, Minnesota lands righty Peterson

With their 13th-round pick, the Twins drafted right-hander Brandon Peterson out of Wichita State, No. 380 overall.

A Savage, Minn., native, Peterson served as a closer for the Shockers in 2013 and pitched 40 innings with 26 appearances. He accumulated a 1.12 ERA with 42 strikeouts and a 3-1 record.

At 6-foot-1, 198 pounds, Peterson has a fastball that touches 95 mph and consistently falls at 90, which he pairs with a slider.

"He's got some pretty good tools," scouting director Deron Johnson said. "He's running up to 95 and he's got a good slider. He's not as big as [Twins' 12th-round pick Ethan] Mildren, but he's a bulldog on the mound."

Twins get college speedster Granite in 14th

In the 14th round of the First-Year Player Draft, the Twins selected outfielder Zack Granite at No. 410 overall.

A junior out of Seton Hall, Granite led his team with 35 stolen bases in 2013 -- second in the Big East and eighth nationally. Over the season, the 5-foot-9, 185-pound center fielder posted a .990 fielding percentage and a .304 average at the plate. He had 21 multihit games and 30 RBIs.

"He can really run," scouting director Deron Johnson said. "He's a plus runner, not a lot of power, but he's got good bat control. He plays a small man's game. He's a good bunter and he can spray the ball around; he's a gap-type hitter."

Granite earned First-team All Big East honors in 2013 and is the second Pirate to be drafted by the Twins this year -- righty Brian Gilbert was taken in the seventh round.
