Here's a look at the top offensive performers in each league for the week ending May 18:
Gregory Polanco, Indianapolis
(.591/.654/1.000, 6 G, 13-for-22, 4 2B, 1 3B, 1 HR, 9 RBI, 6 R, 4 BB, 2 K, 2 SB)
While the debate rages on about his proper place in the Pirates system, Polanco continues to do nothing but hit, as seen last week when he compiled four multi-hit games and three contests with three hits or more. The Pirates top prospect, who now has two IL Player of the Week honors to his name this season, leads the Triple-A circuit in batting average (.389), OBP (.453), slugging percentage (.623), hits (63), total bases (101), runs (30) and RBIs (38). With the Bucs getting little production from their right fielders this season, Polanco will likely join the big club once the Super Two deadline passes sometime next month.

Jimmy Paredes, Omaha
(.400/.483/.800, 6 G, 10-for-25, 2 2B, 1 3B, 2 HR, 12 RBI, 7 R, 4 BB, 5 K, 2 SB)
To hit for the cycle might be good enough to win this award by itself. To collect eight RBIs in a week definitely is. Well, Paredes did both Monday in the Storm Chasers' 19-1 win over New Orleans. "That was awesome," he told MiLB.com. "Every day I go to play hard. I play hard, do the best I can. I put all my energy into the game. …You give love to your dad, your mom ... and to love the game is so important."

Christian Walker, Bowie
(.458/.500/.833, 6 G, 11-for-24, 3 2B, 2 HR, 6 RBI, 5 R, 2 BB, 5 K)
There were concerns about the 23-year-old first baseman's power coming into the season, but he's doing his best to put those to bed. With homers in back-to-back games last week, Walker has hit nine in 41 games this season with the Baysox, tied for second-most in the Eastern League this season and only two fewer than he slugged in 103 contests across three levels in 2013. He owns a .325/.368/.533 slash line this season and has captured the circuit's Player of the Week award twice, the first coming April 21.

Jeremy Hazelbaker, Chattanooga
(.455/.500/.818, 6 G, 10-for-22, 2 2B, 2 HR, 5 RBI, 4 R, 2 BB, 5 K, 2 SB)
Acquired from the Red Sox in the offseason, Hazelbaker is heating up in his first year with the Dodgers. After batting .278 with an .810 OPS in April, the 26-year-old outfielder has those numbers up to .333 and 1.001 in 16 May contests. With two more steals last week, he has 10 in 38 games this season, a sign he still has the speed that helped him accrue at least 36 steals in each of his four full Minor League seasons. Despite not tripling last week, Hazelbaker is tied for the Minors lead in the category with seven for the Lookouts.
Alex Yarbrough, Arkansas
(.385/.484/.885, 6 G, 10-for-26, 2 2B, 1 3B, 3 HR, 14 RBI, 9 R, 5 BB, 6 K, 1 SB, 1 CS)
A move to the Texas League hasn't done much to slow down the Angels' No. 9 prospect. Following his best week of the season -- during which he hit his first three homers of the season -- Yarbrough's slash line through 42 games with the Travelers (.314/.351/.456) bares a striking resemblance to the one he put up with Inland Empire (.313/.341/.459) a season ago. "Everyone says, and I agree, that the biggest jump is from high-A to Double-A," he said after his two-homer, six-RBI game last Thursday. "Every pitcher you face has plus stuff and plus command. I've felt pretty consistent for the most part and my confidence keeps growing more and more that I play at this level. I've been pretty happy with it thus far."

Chris Jacobs, Rancho Cucamonga
(.458/.536/.875, 6 G, 2 2B, 4 HR, 9 RBI, 6 R, 3 BB, 4 K)
Now in his third straight season in the Cal League, Jacobs is putting up numbers that could see him back in the Southern League, where he began the 2013 season, before too long. The 25-year-old first baseman, who collected a season-high four hits Wednesday, is batting .325 with 10 homers, 38 RBIs and a 1.036 OPS through 43 games with the Quakes. This is his first Player of the Week honor since entering the Dodgers system in 2007.
Joey Gallo, Myrtle Beach
(.529/.714/1.529, 7 G, 9-for-17, 2 2B, 5 HR, 8 RBI, 9 R, 9 BB, 1 K, 1 SB)
Just when we all though Gallo couldn't play any better in the Carolina League, the Rangers' No. 4 prospect took his game to another level, particularly on the power end. If you took his five homers on the week -- three of which came Friday alone -- that'd still be good enough for seventh-best in the Carolina League for the whole season. As it stands, his 18 homers not only lead the league by eight but are also tops in the Minors, beating out the 15 put up by Adam Duvall and Peter O'Brien. The left-handed-hitting slugger continues to rake with a .342/.459/.795 triple slash in 42 games with the Pelicans.

Florida State League
Patrick Leonard, Charlotte
(.348/.400/.783, 6 G, 8-for-23, 1 2B, 3 HR, 8 RBI, 6 R, 2 BB, 6 K, 1 SB)
The 21-year-old first baseman started with a bang, going 4-for-4 with two homers and five RBIs on Monday, and that was enough to carry him through to the award this week. After batting just .225 with nine homers and a .648 OPS in 123 games with Class A Bowling Green last season, Leonard is off to a better start with the Stone Crabs this season with a .302 average, .944 OPS and seven homers already in just 38 games.
Eric Aguilera, Burlington
(.500/.552/.875, 7 G, 12-for-24, 3 2B, 2 HR, 9 RBI, 4 BB, 2 K, 1 SB)
Since moving up to Inland Empire for an 11-game spell at the end of April, Aguilera has played like a man on a mission to return. Punctuated by four consecutive multi-hit games to end last week, the 23-year-old first baseman is batting .341 with two homers (his only two of the season) and 10 RBIs in 11 games with the Bees this month.
South Atlantic League
Ashley Graeter, Asheville
(.611/.650/1.389, 5 G, 11-for-18, 5 2B, 3 HR, 5 RBI, 7 R, 1 BB, 2 K, 4 SB, 1 CS)
Signed by the Rockies as a non-drafted free agent in 2012, Graeter is making his full-season debut with the Tourists, and so far so good for the 24-year-old, who has gotten time at first base, catcher and DH. He collected 10 hits in a three-game span between Thursday and Saturday, pushing his average up to .383 through 13 games with Asheville.
