The Blue Jays made it back-to-back left-handers when they chose Tim Mayza in the 12th round with the 355th pick of the 2013 First-Year Player Draft on Saturday.

Mayza came into his junior year at Millersville University as Baseball America's sixth-best Division II prospect, and he didn't disappoint.

The 21-year-old was named All-PSAC East, and All-Atlantic Region First Team by Daktronics, and was a semifinalist for the Tino Martinez Award as the top Division II collegiate player.

Mayza went 11-3 in 15 starts for Millersville, posting a 1.55 ERA with 1.01 WHIP and 91 strikeouts in 98 2/3 innings on the mound.

His greatest strength may come from his ability to shut down left-handed hitters, who hit only .190 against him on the season.

Blue Jays tab Brentz in the 11th round

Draft Report: Jacob Brentz, HS Pitcher

It didn't take long for the Blue Jays to return to what they've been doing throughout the entire 2013 First-Year Player Draft on Saturday.

After taking their first, and so far only, positional player in the 10th round, Toronto went back to selecting high-upside arms.

The Blue Jays chose left-handed high school pitcher Jacob Brentz in the 11th round with the 325th overall pick.

2013 Draft Central

Brentz, 18, is 6-foot-2 from Parkway South Senior High School in Missouri.

He's a 2013 Rawlings 1st Team All-American Central -- All Region 1st Team, who can hit 97 mph with his fastball.

Brentz is a two-way standout from the Missouri high school ranks, who's also shown some ability to spin a breaking ball to complement his impressive fastball.

Although the lanky lefty is still pretty raw on the mound, only recently did he find himself pitching after years in the outfield.

Locastro heads to Toronto in 13th round

The Blue Jays strayed from pitching for only the second time in the 2013 First-Year Player Draft in the 13th round, selecting Ithaca College shortstop Timothy Locastro with the 385th pick.

Locastro, 20, was coming off a spectacular sophomore season, and bested that as a junior, hitting .436, with a .553 on-base percentage, and four home runs, 36 RBIs and 71 runs scored in 48 games.

Locastro bats and throws right-handed, and has good speed, stealing 40 bases in 41 attempts.

The Division III prospect was named a Second-Team All-America by D3baseball.com.

Toronto picks power-hitting Dantzler in 14th

For the first time, the Blue Jays chose back-to-back positional players -- selecting power-hitting first baseman L.B. Dantzler from the University of South Carolina in the 14th round with the 415th pick of the 2013 First-Year Player Draft.

The 5-foot-11, 200-pound senior hit a Southeastern Conference-best 15 home runs, and stood second with a .648 slugging percentage.

His power, however, also makes Dantzler a free swinger, as he led South Carolina with 46 strikeouts. The left-handed batter does possess a solid eye at the plate, though, walking a team-high 36 times.

Dantzler also hit .332, with a .445 on-base percentage and 48 RBIs, and earned the prestigious Capital One Academic All-American of the Year award from the College Sports Information Directors of America.

Toronto chooses OF Davis in 15th round

The Blue Jays wrapped up the 15th round of the 2013 First-Year Player Draft on Saturday with their third consecutive position player, but only their fourth of the entire Draft, selecting outfielder Jonathan Davis with the 445th pick.

Davis, 21, regressed in his junior year at the University of Central Arkansas. The speedy Camden, Ark., native hit only .268 with three home runs, 49 RBIs, 48 runs scored, and 25 stolen bases in 2013.

His on-base percentage was solid at .416, but his average was nearly 80 points lower than his first two seasons playing collegiate ball.

Despite not having the same success as a junior, Davis was previously the Southland Conference Freshman of the Year and a Louisville Slugger Freshman All-American in 2011.

In the Pipeline

Although eight of the top 10 Blue Jays prospects are pitchers, the club decided that there was no such thing as too many arms. The Blue Jays picked up 22 pitchers in the 2013 First-Year Players Draft, including 11 of their first 12 selections. First-round pick Phillip Bickford and company join a system that includes Aaron Sanchez, Roberto Osuna, Daniel Norris, and Marcus Stroman.
