Pitching Prospect of the Day: Robert Stephenson, RHP, Reds (Low-A Dayton): 5.0 IP, 5 H, 1 ER, 1 BB, 9 K; Stephenson has an elite fastball with the chance for two plus secondary offerings (slider/changeup). I talked with a scout about the Reds’ system, and he said, “Watch out for Stephenson. He might be the best prospect in the system, and I don’t care how fast Hamilton is.”

Position Prospect of the Day: Andrew Lambo, LF, Pirates (Double-A Altoona): 4-6, 2B, 3B, HR, 4 R, 3 RBI, K; Lambo, a onetime upper-tier prospect, has started 2013 swinging a hot bat. He hit for the cycle after making this list a few nights ago because of a three-hit performance; .417/.500/.833 with two doubles, a triple, and two home-runs in 24 at-bats.

Other notable prospect performances from April 9:

“The Good”

  • Raul Alcantara, RHP, Athletics (Low-A Beloit): 7.0 IP, 1 H, 0 ER, 0 BB, 6 K; Alcantara, acquired by Athletics in the Andrew Bailey deal, has a plus fastball that he can command to both sides of the plate and mixes in a solid slider and changeup.
  • Jayce Boyd, 1B, Mets (Low-A Savannah): 3-5, 2B, R, RBI, K; Boyd has excellent bat-to-ball ability, but his lack of over-the-fence power and first-base defensive profile don’t mesh well; 12-for-22 with four doubles.
  • Edward Butler, RHP, Rockies (Low-A Asheville): 6.0 IP, 2 H, 0 ER, 4 BB, 7 K; Butler, a 2012 supplemental first-round selection, has a fastball that sits in the plus velocity range and can touch plus-plus when necessary. In addition, he brings a slider that flashes bat-missing ability and a changeup that is still a work in progress; 14 innings pitched, three hits allowed, and 14 strikeouts.
  • Andrew Chafin, LHP, Diamondbacks (Hi-A Visalia): 7.0 IP, 4 H, 0 ER, 1 BB, 10 K; Chafin shows a plus fastball and a plus slider, but he uses a max-effort delivery that will at some point turn him into a late-inning reliever.
  • Christian Lopes, 2B, Blue Jays (Low-A Lansing): 3-4, HR, R, RBI, K; Lopes makes loud contact and a lot of it because of a short quick bat, but he is limited to the right side of the infield because of below-average speed and range.
  • Luis Mateo, RHP, Mets (High-A St. Lucie): 6.2 IP, 4 H, 0 ER, 2 BB, 9 K; A plus fastball mixed with a 70-grade, wipeout slider makes Mateo one of the more interesting prospects in the Mets system. The changeup is still a complete work in progress, and he is already 23, which leads me to believe the Mets could fast track Mateo with a move to the bullpen at any point.
  • Jiovanni Mier, SS, Astros (Double-A Corpus Christi): 3-3, HR, R, 2 RBI, BB; Mier, a first-round pick in 2009, shows only average tools at the plate, but has flashed gap power. His defense is only considered average, and he is now looked at more as a utility option than as a regular starter.
  • Rafael Montero, RHP, Mets (Double-A Binghamton): 6.0 IP, 6 H, 1 ER, 0 BB, 7 K; Montero features a plus fastball with an average slider and changeup. He has plus command of all of those pitches, which will allow him to eventually slot in nicely behind Zack Wheeler and Matt Harvey in the Mets rotation.
  • Domingo Santana, RF, Astros (Double-A Corpus Christi): 3-4, 3 2B, R, 2 RBI, BB, K; Potential plus-plus power and a plus arm make Santana a good fit for right field. Making consistent contact has always been his problem, and he will continue to work at it in Double-A.
  • Jesus Solorzano, RF, Marlins (Low-A Greensboro): 3-5, 2B, R, 5 RBI, SB; Solorzano has plus power potential, but will need to improve his plate discipline and routes to the ball in the outfield; .391/.391/.522 in 23 at-bats.
  • Jose Urena, RHP, Marlins (High-A Jupiter): 6.0 IP, 3 H, 1 ER, 0 BB, 7 K; Urena mixes a potential plus-plus fastball with a slider that flashes plus, a developing changeup, and a get-me-over curveball. Urena has the ability to miss bats, but must keep working to develop his changeup and improve his command in order to reach his third-starter ceiling.
  • Jose Vinicio, SS, Red Sox (Low-A Greeville): 3-4, HR, R, 2 RBI; Vinicio, a $1.95 million Dominican signee in 2009, shows the chops to stick at shortstop and good bat speed. He must add mass to his extremely small frame.

 “The Bad”

  • Billy Hamilton, CF, Reds (Triple-A Louisville): 0-3, BB, K, CS; Man, someone better give Billy the red light… he got caught stealing.
  • Joe Terdoslavich, RF, Braves (Triple-A Gwinnett): 1-5, 2B, 4 K; Terdoslavich has limited defensive ability, which puts extreme pressure on his production at the plate; 5-for-22 with six strikeouts to date.
  • Jesse Winker, LF, Reds (Low-A Dayton): 0-3, 2 K; Winker, a 2012 supplemental first-round selection, might already be restricted to left field. He will rely on his bat, which is his best tool, but will need to develop power to fit the corner-outfield profile.

“The Ugly”

Adalberto Mondesi, SS, Royals (Low-A Lexington): 0-6, BB, 6 K; just 24 hours after being on this list for all the right reasons, Mondesi had a very forgettable night.
