A's select righty Trivino to kick off Day 3 of Draft

Lou Trivino went 7-5 with a 1.83 ERA in his junior year at Division II Slippery Rock, striking out 92 batters and walking just 18. He finished the season having thrown 83 2/3 innings, with eight of his outings going for complete games.

The A's drafted Trivino with their 11th-round pick on Saturday to start off their selections for Day 3 of the 2013 First-Year Player Draft.

The 6-foot-5, 225-pound right-hander has an active fastball, cutter, changeup, slider and curveball in his arsenal.

He threw three straight shutouts during his 2013 campaign -- five total -- and also threw a no-hitter. He posted quality starts in 11 of his 12 outings.

The first-team All-PSAC West honoree leaves Slippery Rock as the holder of the school record in career strikeouts and single-season strikeouts, with 227 and 92, respectively.

A's add another right-hander in Freese

Dakota Freese, a right-hander from Des Moines Area Community College, was selected with Oakland's 12th-round pick on Saturday.

Freese went 7-1 in 12 starts in 2013, logging 61 innings with a 2.66 ERA and 90 strikeouts.

The 6-foot-3, 190-pound Iowan throws in the low 90s and has a respectable curveball.

He was previously a 34th-round selection by the White Sox in 2011, but opted for college with intentions of improving his chances of being drafted higher. His Draft stock may have been hurt in 2011 after he missed the early part of his senior year because of a school-imposed suspension.

A's take free-swinging Higley in 13th round

Justin Higley finished the 2013 season with a .252 batting average in 210 at-bats for Sacramento State.

The A's 13th-round pick also hit 10 home runs, but he struck out 55 times with just 22 walks.

The 6-foot-4, 200-pound outfielder bats lefty and throws righty. He's stated that one of his professional aspirations is to become a police officer.

Higley was used in multiple spots in the lineup while at Sacramento State, batting in the first, second, fourth, fifth and sixth spots in the order.

Lomangino was a top right-hander in the Big East

At 6-feet tall, 205 pounds, James Lomangino was one of the top pitchers in the Big East. He finished 2013 with a 3.79 ERA despite going 2-6 in 15 starts.

The A's selected Lomangino with their 14th-round pick. He matched a career-high 10 strikeouts as part of his first career complete game against Notre Dame toward the end of the season with St. John's University to bump him up to second in the conference in strikeouts.

He ended the season tied for third in the category.

A's select Diaz, son of former big leaguer, in 15th round

Edwin Diaz's father, also named Edwin, was a second-round pick in 1993, but the 6-foot-2, 180-pound high schooler from Puerto Rico didn't go as high as his dad did.

The A's selected Diaz with their 15th-round pick of the Draft on Saturday.

Diaz is a reliable defender at short, but scouts are split on whether he can remain at the position due to fringy range and arm strength.

At the plate, he projects to be an average hitter who should add more power as he fills out. Oakland's selection suggests it feels confident that he can play shortstop in the Major Leagues.
