Inspired by the “in-a-box” feature presented by Bill James in “The New Historical Baseball Abstract,” here is a review of some of the standout performances from the low Class A Midwest League in 2015.

League Champion
West Michigan (Tigers) defeated Cedar Rapids (Twins) three games to two in the finals.
Best Record
Quad Cities (Astros) went 88-50 (.638) but lost to Cedar Rapids in the first round of the playoffs.

Best Offense
Lake County ranks No. 1 in the MWL with a park-adjusted OPS+ of 111. Team leaders: 1B Bobby Bradley (181 OPS+), 2B Claudio Bautista (148) and CF Greg Allen (129).
Home-Field Advantage
Kane County featured the highest park factor in the MWL at 117. Cougars home games featured nearly nine runs per game and road games about 7.6.
League MVP
Lansing 1B Ryan McBroom hit .315/.387/.482 (143 OPS+) with 12 home runs in 127 games. He led the MWL in on-base percentage and with 39 doubles and ranked second in batting, RBIs (90), slugging and extra-base hits (52).
Percentage Of .300 Hitters (Among Those Who Batted 300 Times)
9 percent (10 out of 114)
Batting Champion
Kane County SS/2B Ildemaro Vargas hit .321, edging league MVP Ryan McBroom by six points. The Diamondbacks signed the 24-year-old Vargas this May after he had been released by the Cardinals (he also spent 30 games in the Atlantic League). He has eight years of pro experience and previously reached the high Class A Florida State League in 2014.
Most Home Runs
Lake County 1B Bobby Bradley led the MWL with 27 home runs. No other player hit more than 16.
Most Aggressive Baserunner
Peoria SS Oscar Mercado stole a league-leading 50 bases in 69 tries, hit three triples and scored 70 runs in 117 games.
Most Power
Not only did Lake County 1B Bobby Bradley lead the MWL with 27 homers, but he also paced the circuit with 92 RBIs and a .529 slugging percentage.
Best Switch-Hitter
Lake County CF Greg Allen hit .273/.368/.382 (129 OPS+) with 27 doubles and 43 steals in 123 games.
Top Power-Speed Player
West Michigan RF Mike Gerber hit 13 home runs and stole 16 bases, but as a four-year starter at Creighton, he turned 23 in July and was older than the MWL average this season. For a younger alternative, South Bend RF Jeffrey Baez hit nine homers and stole 34 bases.
Most Well-Rounded Player
West Michigan RF Mike Gerber scored above the league average (among those who qualified for our Top 20 ranking) for power (90th percentile), walk rate (50th), strikeout rate (70th), average on balls in play (70th) and speed (60th).
Best Prospect Who Did Not Qualify For League Top 20
Burlington C Taylor Ward, the 26th overall pick in June, went 32-for-92 (.348) with 10 walks in 24 games.
PITCHING STANDOUTS

Best Pitching Staff
Quad Cities ranks first in park-adjusted ERA+ at 140. Team leaders: RHP Francis Martes (379 ERA+), RHP Justin Ferrell (202) and RHP Josh James (150).
Home-Field Advantage
Lake County (87) played as the top pitcher’s park, though the MWL featured a narrow spread of run-scoring contexts.
League Pitcher Of The Year
The MWL does not name a pitcher of the year.
ERA Champion
Peoria RHP Matt Pearce led the MWL with a 2.43 ERA, though he only narrowly edged out Dayton RHP Tyler Mahle by a margin of 2.426 to 2.428.
Most Strikeouts
Peoria LHP Austin Gomber struck out 140 batters.
Strikeout Artist
Three pitchers struck out at least 30 percent of batters faced: Cedar Rapids LHP Stephen Gonsalves (36.8 percent), Bowling Green RHP Hunter Wood (33.3) and Lansing RHP Sean Reid-Foley (30.7).
Control Artist
South Bend RHP Ryan Williams walked just two of 195 batters faced (1 percent) and promptly moved up to Double-A Tennessee.
Best Command
Dayton RHP Tyler Mahle recorded a +110 differential between strikeouts (135) and walks (25), indicating that batters struggled to handle his pitches even when located in the strike zone.
Tough To Square Up
Neither West Michigan RHP Spencer Turnbull (117 innings) nor Wisconsin LHP Kodi Medeiros (93 innings) allowed a home run. In fact, the former is the first full-season starter in at least 10 seasons to both qualify for the minor league ERA title and not allow a home run.
Best Prospect Who Did Not Qualify For League Top 20
Quad Cities RHP Joe Musgrove went 4-1, 0.70 with a 23-to-1 strikeout-to-walk ratio in his five league appearances, but he fell about 20 innings short of qualifying.
Most Well-Rounded Pitcher
The well-rounded nature of Quad Cities RHP Francis Martes‘ game marked him as a fast-riser in the Astros system, and he finished the season at Double-A Corpus Christi. In the MWL, he ranked above the league average (among those who qualified for the Top 20) for home run rate (90th percentile), strikeout rate (80th), walk rate (50th), opponent average (90th) and ground/fly ratio (60th).
FIELDING STANDOUTS

Best Double-Play Combo
Once adjusting for the estimated impact of baserunners on double-play opportunities, the Lake County middle infield comes out ahead with the highest adjusted rate of double plays per game. SS Yu-Cheng Chang (71 double plays) and 2B Claudio Bautista (42) were the regular double-play combo, but they received help from SS Yonathan Mendoza (19) and 2Bs Steven Patterson (26) and Ordomar Valdez (26).
• West Michigan middle infielders recorded the best fielding average (.969), while Kane County middle infielders recorded the highest unadjusted rate for double plays per game (.708).
Playmakers
Leaders at their position in total chances—or “touches”—per game. Minimum 70 games at position required (45 games for catchers). This is essentially range factor—to those familiar with that metric—plus errors.
Pos Player Team Org TC/G
C Francisco Mejia Lake County Indians 9.28
1B Avain Rachal Dayton Reds 10.52
2B Darren Seferina Peoria Cardinals 4.42
3B Joe DeCarlo Clinton Mariners 3.07
SS Luis Gonzalez Dayton Reds 5.24
LF Charcer Burks South Bend Cubs 2.17
CF Thomas Milone Bowling Green Rays 2.91
RF Justin Williams Bowling Green Rays 2.40
Armed And Dangerous
Cedar Rapids C Brian Navarreto led the MWL by throwing out 56 percent (50-for-89) of basestealers. The Twins made him a sixth-round pick in 2013 from high school in Jacksonville.
• A pair of 2014 second-round picks out of high school tied for the MWL lead with 21 outfield assists. Great Lakes CF Alex Verdugo and Fort Wayne CF Michael Gettys both reached that total.
