PHILADELPHIA -- Another pick on Saturday, another high school pitcher from Colorado for the Phillies. And Colorado has been good to the Phillies -- think Roy Halladay and Brad Lidge.

The Phillies selected right-handed pitcher Griffin Jax with their 12th-round pick of the 2013 First-Year Player Draft (361st overall). Jax is from the Denver area, and the Phillies used their first choice of the afternoon on Denton Keys, a left-handed pitcher from Rye, Colo.

Jax was a standout at Cherry Creek High School, where he excelled on the mound and at third base. He is currently committed to play baseball for the Air Force Academy. Lidge also attended the same high school as Jax.

As a pitcher for Cherry Creek in 2013, Jax had a 1.74 ERA, limited opponents to a .191 batting average and struck out 57 hitters in 40 1/3 innings.

Jax was the fourth straight pitcher the Phillies had selected, starting with Shane Martin on Friday at 271.

Phils draft Keys, who threw four no-nos this spring

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

PHILADELPHIA -- The Phillies began Day 3 of the 2013 First-Year Player Draft on Saturday by selecting high school pitcher Denton Keys.

A lefty from the small town of Rye, Colo., Keys was taken in the 11th round and 331st overall. Keys, who is listed at 6-foot-3 and 190 pounds, has committed to play for Kansas, and he'll soon have to make a decision between the Phillies and the Jayhawks.

Keys mowed down batters at the high-school level, and this spring, he threw four no-hitters -- one of which was a perfect game.

In total, Keys had a miniscule 0.15 ERA and struck out 115 batters in 45 2/3 innings for Rye High School this season. He was also named to the Rawlings 2013 West All Region First-Team.

Football star Martarano drafted by Phils in 13th

Draft Report: Joey Martarano, HS Third Baseman

PHILADELPHIA -- Two-sport star Joey Martarano has options.

A native of Fruitland, Idaho, Martarano has committed to play linebacker on the blue turf of Boise State's football field, but he was also selected at No. 391 overall in the 13th round by the Phillies in the First-Year Player Draft on Saturday.

Martarano reportedly told coach Chris Petersen recently that he intends to play football for the Broncos. However, the school does not have a baseball team, so the Phillies may be able to work out a deal that allows Martarano, who played third base in high school, to play college football and professional baseball.

"Just got drafted to the phillies!" Martarano tweeted Saturday afternoon. "Im still playing football but i can show up and play baseball whenever i want for 100k! #pumped"

Listed at 6-foot-4 and 235 pounds, Martarano has lots of power, which allows him to succeed on the diamond and gridiron. If Martarano does choose to play baseball professionally, he will likely move to the outfield or first base.

Dove first Phillies college player taken on Day 3

PHILADELPHIA -- The Phillies shook a trend of taking Day 3 high schoolers when they selected Georgia Tech infielder Samuel Dove with the 421st overall pick in the 14th round of the First-Year Player Draft on Saturday.

Unlike many of the high-school prospects who were selected this weekend, Dove did not have many choices on the diamond when he was younger and had to walk on at Georgia Tech. Dove eventually earned a starting role and was in the lineup for 61 of the Yellow Jackets' 64 games in the 2013 season.

Dove hit .288 with 34 RBIs and a .371 on-base percentage, while primarily playing second base last season. In his time at Georgia Tech, the 22-year-old also played left field and third base.

Phillies take Troy star Pierce in 15th round

PHILADELPHIA -- Logan Pierce put up big numbers while playing at Troy University, and the Phillies scooped him up in the 15th round (451st overall) in the First-Year Player Draft on Saturday.

Pierce, a 6-foot third baseman, led a 42-win Troy squad with a .364 average, and he also drove in 63 runs in his senior season.

Playing at Troy was comfortable for Pierce. The 23-year-old was playing in his hometown, and the Trojans' manager was Bobby Pierce, Logan's father.

Pierce also had a strong 2012 campaign, as he hit .351, scored 51 times and was an All-Sun Belt First-Team selection. At one point during the 2011 season, Pierce was named the Louisville Slugger National Hitter of the Week.
