Who’s No. 1: The Blue Jays’ No. 7 prospect, Roberto Osuna threw just 23 combined innings last year, the vast majority (22) in the Florida State League as he returned from Tommy John surgery. He did go to the Arizona Fall League as well, but he joins the Toronto bullpen having thrown 129 total pro innings.

Who’s No. 1: Some day Bryce Harper will no longer be the youngest player in the National League, but with 56 big league home runs and 360 games played, he’s still younger than anyone else in the NL. This is the third consecutive year that he has been the youngest player in the league on Opening Day, though this time it is a function of an older league. In the American League, Harper would rank eighth.

Who’s No. 1: Jose Peraza, the Braves No. 2 prospect now that Matt Wisler has joined the club, ranked 54th on our Baseball America Top 100 Prospects coming into the season. Peraza is the Braves’ heir apparent at second base, though Jace Peterson is impressing in Atlanta, which might buy some time for Peraza to get more seasoning.

Who’s No. 1: Carlos Garay, a Venezuelan catcher, is the one name that doesn’t fit on this list. He is expected to be a short-term backup at Triple-A. He did not rank among the Rangers’ Top 30 Prospects last season and he comes into the year with just seven games about Rookie ball. Herrera, the Mets’ No. 4 prospect coming into the season, will likely take over the top spot before long.

Who’s No. 1: Zach Eflin, the No. 9 Padres prospect before his trade to the Phillies, is one of the more advanced high school pitchers drafted in recent years. Despite his youth, he’s been on a steady one-level-a-year progression. He led the Midwest League in ERA in 2012 (2.73) and was third in the California League last year at 3.80.

Who’s No. 1: The White Sox are traditionally aggressive in their promotions timetables for prospects, but in Tyler Danish‘s case, a jump to the Southern League was a very easy decision. Danish, the team’s No. 7 prospect, went 5-3, 2.65 in the Carolina League last year. Danish succeeds thanks to a solid sinker, an improving slider and a changeup he has significantly refined as a pro.

Who’s No. 1: Julio Urias has been the youngest player in every full-season league he’s played in. The No. 3 prospect in the Dodgers system and the 10th best prospect overall, scouts said two years ago that Urias could probably succeed in Double-A as a 16-year-old. Now he’ll get to prove he can handle the level as an 18-year-old. With an 89-94 mph fastball that touches 97 and a quality changeup and curveball, Urias is equipped to handle an aggressive assignment.

Who’s No. 1: If you are looking at aggressive assignments to start the season, none are more aggressive than the decision to send Franklin Barreto to the California League. Barreto, acquired last offseason in the Josh Donaldson deal, spent all of last season in the Northwest League. But the shortstop has a long track record of playing against advanced competition, going back to his days with the Venezuelan youth national teams. And if a hitter is going to be challenged, the hitter-friendly California League is a good place to do it. In 2013, the Athletics jumped Addison Russell to Stockton with just a 13-game pit stop in the Midwest League the year before as preparation, so they have a history of having this work out.

Who’s No. 1: Wendell Rijo, the Red Sox’s No. 24 prospect, has a solid chance to become an above-average offensive second baseman. One problem—he’s in an organization heavy with above-average offensive second baseman, starting with Dustin Pedroia, Mookie Betts and Yoan Moncada. Rijo needs to show defensive improvement at second, but offensively, he’s got a chance to hit for average with a little more pop than the average second baseman.

Who’s No. 1: Amed Rosario, the Mets No. 6 prospect, gets to skip a full season in the South Atlantic League thanks in part to the Mets’ healthy logjam of shortstops. Every full-season level has a shortstop with at least some big league potential. Matt Reynolds is at Triple-A Las Vegas, 2012 first-rounder Gavin Cecchini is playing for Double-A, Rosario jumps to high Class A and defensive whiz Luis Guillorme heads to low Class A Savannah.

10 Reese McGuire Bradenton (Pirates) 1995-03-02


Who’s No. 1: Gleyber Torres, the Cubs No. 8 prospect, jumps straight to full-season ball after 43 games in the Arizona Rookie League and an additional seven in Boise last summer. A $1.7 million signee out of Venezuela in 2013, Torres adds to the Cubs massive glut of middle infielders. It’s a good problem to have.

Who’s No. 1: Ricardo Sanchez came to the Braves last offseason in the trade that sent Kyle Kubitza and Nate Hyatt to the Angels. The lefthander spent last year in the Arizona League, so this is an aggressive promotion. Sanchez has a smooth and easy delivery, but he’s still working on throwing strikes consistently and at times he’s had to dial back his 93-95 mph fastball to locate it better.
