Toledo – Adam Wilk (LHP)
Adam Wilk has been cranking out fine minor leagues seasons since he joined the Tigers following the 2009 draft. While he struggled in the big leagues in 2011, he has jumped right back into pitching superbly in the minor leagues this season. He topped everything off with a sparkling 1.11 ERA in five July starts, finishing with a 1-1 record. In 32 1/3 innings, Wilk allowed only 21 hits and 11 walks while fanning 31 batters en route to one of the best months of his professional career. His .188 batting average against further illustrates his July dominance.

Erie – Bruce Rondon (RHP)
Much has been made of Bruce Rondon this season, what with his triple-digit heat, Futures Game performance and rapid promotion through the system. After dominating the Florida State League, Rondon was "tested" at Double-A, but he dominated there as well. In twelve reliever appearances for Erie, Rondon has allowed eleven hits and eight walks while striking out 15 batters. His performance netted him a 0.73 ERA and five saves, earning him yet another promotion to Triple-A.
Runner-Up – Michael Morrison (RHP)
Lakeland – Tyler Clark (RHP)
Backfilling Rondon in Erie is right-hander Tyler Clark who has been equally as dominating with High-A Lakeland. In nine appearances, Clark picked up six saves with 12 1/3 innings pitched. He has allowed just five hits and one walk while striking out a ridiculous 21 hitters. Aside from his six saves, Clark posted a 2-1 record and .128 batting average against, making him one of the FSL's most dominating relievers. While Rondon works his magic with overpowering stuff, Clark relies on location, mixing pitches and some deception to get outs.
Runner-Up – Luis Sanz (RHP)
West Michigan – Marcelo Carreno (RHP)
After posting a 4.55 ERA in 24 games (23 starts) with West Michigan last year, the 21-year old right-hander was sent back to the Midwest League for another shot at the league. He has improved across the board in 2012 and capped it all off with a spectacular performance last month. In five starts, Carreno notched a 2-2 record and 2.81 ERA. He tossed 25 2/3 innings, allowing only 14 hits and one home run, while walking only four batters and punching out 19.
Runner-Up – Melvin Mercedes (RHP)
Connecticut – Endrys Briceno (RHP)
Briceno made a big jump in the mid-season update to the TigsTown Top 50 and his July performance should at least hint at why the staff felt he deserved the aggressive movement. After posting a 14.63 ERA in two June starts, Briceno settled in with a 2.67 ERA in six starts in July. He compiled a 3-1 record on the heels of just 21 hits in 30 1/3 innings. While he did walk 15 batters, he did manage to strike out 20 and keep the ball in the park by allowing only one home run.
Runner-Up – Josh Turley (LHP)
GCL Tigers – Jake Thompson (RHP)
The Tigers top pick in June, the 6-foot-4, 235 pound right-hander wasted no time dominating his first professional opponents. In four starts before being shut down for the season, Thompson put up a miniscule 1.45 ERA across four starts. He tossed just 18 2/3 innings, but allowed only seven hits along the way, walking another seven and striking out an impressive 20 batters.
Runner-Up – Jose Valdez (RHP)
DSL Tigers – Juan Falcon (RHP)
The Tigers signed Falcon just before the DSL season began and he has been a huge help to the club this year. A big 6-foot-3, 200 pound 20-year old, Falcon has a shiny 1.00 ERA for the season. In July he was even better than that, finishing the month (nine relief appearances) with a 0.87 ERA in 20 2/3 innings. He allowed only two earned runs all month, stemming from only eight hits and eight walks allowed. While he only struck out 11 batters, his 2.12 groundball ratio helped him dominate the competition.
Runner-Up – Jesus Guzman (LHP)
VSL Tigers – Eudis Idrogo (LHP)
Just 17-years old, Idrogo has put together a spectacular season with the VSL Tigers. The young lefty has a 1.33 ERA and 5-0 record in eleven games (just one start). Last month's performance was the crowning achievement of his debut season as he was 3-0 with a 0.93 ERA in four games. Across 9 2/3 innings, Idrogo allowed nine hits and two walks while striking out eleven.
