Toledo – Jeff Larish (1B/3B)
As Larish has continued to regain his health and strength from season ending wrist surgery last fall, he has continued to improve his offensive performance. Playing nearly every day as a third baseman in June, Larish's bat yet again caused people to start wondering if he could hit at the big leagues. For the month, Larish saw action in 27 games, ripping International League pitching to the tune of a .307/.404/.602 line. He ripped five doubles and seven home runs en route to driving in 27 runs with 25 walks and 27 strikeouts.

Erie – Andy Dirks (OF)
In a month that saw Dirks and his teammates go winless at home, and the offense struggle mightily, Dirks shone through as a beacon of hope for the struggling team. Playing in almost every game during the month, sitting atop the lineup for many of them, Dirks posted a .333 average with six doubles and four home runs, raising his season totals to 16 and ten, respectively. To cap it all off, Dirks swiped six bases during June, giving him 17 for the season.
Runner-Up: Michael Bertram (3B/1B)
Lakeland – Billy Nowlin (1B)
After struggling in a big way for the first two months of the season, Nowlin finally started showing the bat that earned him acclaim as a prospect after last year's breakout campaign in West Michigan. In the season's first two months, Nowlin slugged just three home runs, and he proceeded to best that total in June alone, with four on the month. He finished the month with a .352/.418/.511 line that includes 16 RBI and nine walks in just 23 games.
Runner-Up: Francisco Martinez (3B)
West Michigan – Jamie Johnson (OF)
It has been a very nice full-season debut for Jamie Johnson in 2010, but nothing he had done in the season's first two months compare to what he accomplished in June. In 21 games as one of the ‘Caps regular outfielders, Johnson hit a whopping .384 with 28 hits, including three doubles and a triple. He drew 12 walks against just 18 strikeouts, and stole four bases while being caught just one time.
Runner-Up: Wade Gaynor (3B)
DSL Tigers – Francisco Contreras (3B)
Signed during the off-season and making his professional debut this summer, Contreras turned in a solid first full month while seeing action in 22 games for the Tigers. Contreras doubled three times and tripled once, though he has yet to slug his first professional home run. He finished his first full month with a solid .296/.351/.366 line that gives hope for his future.
Runner-Up: Samuel Ortiz (INF)
VSL Tigers – Jesus Ustariz (3B)
Another third baseman signed in the off-season and making his official professional debut this summer, Ustariz is a more highly regarded prospect and it showed in his performance during the month of June. Ustariz tore the cover off the ball with a .327 average in 16 games, behind 17 hits. He smoked two doubles and two home runs, and maybe more impressively, he walked six times as opposed to just four strikeouts.
