SoxProspects.com: July's best and worst

Here’s a look at the best and worst performances in the Red Sox minor league system for July. (SoxProspects.com prospect ranking in parenthesis)

Top offensive players in July

(31) Mauro Gomez, 1B, Pawtucket -- .333/.390/.593 with 2 HRs

(34) Juan Carlos Linares, OF, Pawtucket -- .337/.369/.526 with 4 HRs

(NR) Jeremias Pineda, OF, GCL Red Sox -- .436/.470/.553 with 0 HRs and 10 SBs

NR means player is not ranked in the top 60

Gomez’s impressive play in Triple-A Pawtucket earned him two separate call-ups to Boston in July, where he hit .321 in 28 at-bats ... Linares, 28, is capable of playing all three outfield positions, and may be part of Boston’s bench equation in 2013 ... Vazquez has thrown out 42 percent of would-be base stealers for the season, while posting solid numbers at the plate ... Almanzar made history by reaching base in 16 consecutive plate appearances in mid-July, matching the major league record held by Ted Williams ... Pineda, an athletic 21-year-old center fielder out of the Dominican Republic, is leading the Rookie-Level Gulf Coast League in batting average, on-base percentage, slugging percentage, OPS, hits, and total bases.

Top pitchers in July

(14) Henry Owens, SP, Greenville – 2-2, 4.50 ERA, 1.27 WHIP, 25/9 K/BB in 22.0 IP

(53) Yeiper Castillo, SP, Salem/Greenville – 2-1, 1.70 ERA, 1.05 WHIP, 28/13 K/BB in 37.0 IP

(60) William Cuevas, P, Lowell – 4-1, 2.18 ERA, 0.94 WHIP, 35/6 K/BB in 33.0 IP

(NR) Ricardo Betancourt, P, GCL Red Sox – 3-1, 0.00 ERA, 0.97 WHIP, 16/6 K/BB in 22.2 IP

(NR) Francisco Taveras, P, Lowell – 2-1, 1.59 ERA, 1.02 WHIP, 22/10 K/BB in 28.1 IP

Owens, who just turned 20, leads all of the minor leagues with 12.27 strikeouts per nine innings ... After four injury-plagued seasons in Low-A Greenville, Castillo responded well to a July 5 promotion to High-A Salem ... Cuevas has impressed with a low-90s fastball that can occasionally top out around 95 mph ... Betancourt, a 19-year-old Venezuelan lefty, has posted an 0.75 ERA in 36.0 innings between stops in the Dominican Summer League and Gulf Coast League ... Along with Cuevas, Taveras is among the top 10 in the NY-Penn League in ERA for the season.

July underachievers

(6) Bryce Brentz, OF, Portland – .200/.250/.326 with 3 HRs

(19) Jose Vinicio, SS, Greenville – .213/.238/.262 with 1 HR

(25) Frank Montas, SP, GCL Red Sox – 1-4, 7.64 ERA, 1.58 WHIP, 18/8 K/BB in 17.2 IP

(NR) Derrik Gibson, IF, Portland – .187/.260/.209 with 0 HRs

(NR) Ryan Dent, IF, Portland/Pawtucket – .157/.224/.186 with 0 HRs

Brentz’s approach is being tested after cycling through Eastern League competition -- he spent July trying to find a balance between staying aggressive at the plate while managing the strike zone ... Vinicio’s subpar line can be somewhat attributed to the fact that he was returning from a three-week DL stint as the result of a left shoulder contusion ... Montas, a 19-year-old Dominican with a high-90s fastball, has shown solid control, but he’s been too hittable due to lack of deception and movement ... Neither Gibson nor Dent have been able to show much offensive success over extended time in Double-A ... Dent was the 62nd overall draft pick in 2007 while Gibson was the 77th overall pick in 2008 (for contrast, Will Middlebrooks was 174th overall in 2007 and Ryan Lavarnway was 202nd overall in 2008).
