Pittsburgh OF Gregory Polanco, Triple-A Indianapolis: 4-for-4, HR, 3 RBI, R — More of the same for the Pittsburgh outfielder. Now hitting .500 with 1.300 OPS through 10 games.

Baltimore RHP Zach Davies, Double-A Bowie: 1 1/3 IP, 2 H, ER, 2 BB, K — Davies was struck in his throwing elbow by a line drive in the bottom of the second. X-rays on the elbow were negative, but Davies was left with a bruise. The team will determine his status further in the coming days.

Milwaukee RHP Ariel Pena, Triple-A Nashville: 4 IP, 4 H, ER, BB, 8 K — Brewers prospect now has 16 strikeouts in nine innings with just three walks, 2.00 ERA.

Houston RF Domingo Santana, Triple-A Oklahoma City: 3-for-4, 3 2B, BB, RBI, R, K — Monster day for the 21-year-old outfielder, who now has consecutive multi-hit games after a 4-for-28 start.

Chicago 3B Kris Bryant, Double-A Tennessee: 2-for-4, HR, 2B, RBI, R, K — Bryant’s power and advanced approach are both shining through in his first look at upper-level pitching, as he’s slashing .269/.406/.654 through eight games.

Oakland RHP Raul Alcantara, Double-A Midland: 6 2/3 IP, 5 H, 1 R, 1 BB, 7 K — Impressive start to the season for the 21-year-old, who boasts a 0.61 ERA through two Double-A starts.

Milwaukee OF Mitch Haniger, Double-A Hunstivlle: 1-for-4 HR, RBI, R, K — Homers on consecutive days for the Brewers prospect.

Atlanta SS Jose Peraza, Class A Advanced Lynchburg: 3-for-5, R, SB — The speedy shortstop is hitting .324 with .780 OPS and four steals through nine games. The 19-year-old has also started playing more second base, with eight games at the keystone versus just two at short — surprising, considering his strong defensive reputation.

Chicago (NL) LHP Rob Zastryzny, Class A Advanced Daytona: 5 2/3 IP, 7 H, ER, BB, 5 K, HR — A solo homer to Reymond Nunez in the sixth was Zastryzny’s only punished mistake.

Minnesota OF Adam Brett Walker II, Class A Advanced Fort Myers: 2-for-5, HR, 3 RBI, R, K — The Florida State League is supposed to be a tough place for Minor League hitters to hit home runs, although Walker is not your average Minor Leaguer. Big raw in the 6-foot-4, 225-pounder’s swing, reflected in four homers through nine games. Slashing .250/.289/.583 thus far.

Colorado SS Trevor Story, Class A Advanced Modesto: 2-for-2, 2 BB, 2 R, 4 SB — The breakout everybody was looking for from Story last year might be coming a year late. Rockies middle infielder is slashing .415/.478/.683 with nine steals through 10 games. Only red flag is 15 strikeouts thus far, but power/speed combo is impressing right now.

Tampa Bay OF Johnny Field, Class A Bowling Green: 3-for-3, 2 HR, 2 BB, 4 RBI, 3 R — Monster day for the Rays’ 2013 fifth-round pick, hitting .345 with .472 OBP, 1.196 OPS in full-season debut. Channeled fellow Bishop Gorman grad Joey Gallo with the multi-homer game yesterday.

Miami 2B Avery Romero, Class A Greensboro: 3-for-5, 2 2B, R, K — The 20-year-old has three-straight multi-hit games, has struck out just twice in nine contests and boasts a 1.092 OPS. Undersized at 5-foot-8, 190-pounds, Romero needs to work on his defense at second, but the 2012 third-rounder can flat-out hit.
