Mac Williamson (OF, SF)
Williamson, 25, has been summoned for his first call-up as the Giants play out the string while holding onto slim hopes of a wild card berth. He was a highly-touted pitcher in high school, but switched to the outfield while at Wake Forest. During his time in college, Williamson improved his game tremendously at the plate and became a 3rd-round pick in the 2012 draft. Once he entered the Giants system, he exhibited his impressive power immediately, blasting 34 HR in his first 651 AB. Tommy John surgery cost him most of 2014 and Williamson has spent 2015 climbing to the Triple-A level while working to regain his pre-surgery production at the plate. His strong physique (6’5", 240 pounds) is certainly a factor in the plus raw power, but he also exhibits a compact stroke and improving plate discipline while hitting the ball to all fields with authority. Williamson is not a burner on the base paths, but has good speed for his size. Breaking balls have been a source of struggles, creating a substantial swing-and-miss portion to his game. This will obviously be a liability for his batting average, but there's been recent improvement in pitch recognition. Defensively, he can handle all three outfield positions but his arm best suits him for RF. He will work in a reserve role down the stretch, but has the potential to be an impact bat for the Giants in the very near future. Over 1184 career AB Williamson has hit .291/.376/.486 with 50 HR and a 0.44 Eye. (CM)
2015 STATS: Sacramento (AAA) – 189 AB, .249/.370/.439, 12 2b, 8 HR, 1 SB, 0.47 Eye
Richmond (AA) – 259 AB, .293/.366/.429, 16 2b, 2 3b, 5 HR, 3 SB, 0.47 Eye
CURRENT ROLE: Reserve outfielder

Trevor Brown (C, SF)
Brown has cracked his first big-league roster and will give the Giants some extra depth at catcher down the stretch. The 23-year-old was a 10th-round pick out of UCLA in 2012 and is a strong defensive catcher, but not much of a producer at the plate. He owns an athletic frame (6’2", 195 pounds), but is lacking in the speed and power departments. At the plate, Brown shows a balanced stance but loads up his swing with a high leg kick that causes timing issues. His hands can be slow to the ball and he doesn’t utilize much of his lower half. Brown’s swing path can have some leverage but is usually pretty flat through the zone. He will have a tough time handling high-velocity pitches while up with the big club. As catchers often develop later offensively than other position players, there is certainly still a window of time for Brown to improve at the plate. However, he should be viewed primarily as a defensive replacement at this juncture of his career. He’s played sparingly at 1B and 2B throughout his career, but his greatest value is as a receiver handling a pitching staff. Over 1114 career AB, Brown has a slash line of .244/.300/.316 with 7 HR and 0.47 Eye. (CM)
2015 STATS:
Sacramento (AAA) – 283 AB, .261/.319/.343, 17 2b, 2 HR, 1 SB, 0.39 Eye
CURRENT ROLE: Reserve catcher
POTENTIAL: Reserve catcher

Matt E. Duffy (1B, HOU)
Instead of calling up Jonathan Singleton, who already is on the 40-man roster, the Astros called up Matt E. Duffy (not the other Matt Duffy who plays for the Giants). This is Matthew Edward Duffy, a 26-year-old 1B and 3B who stands 6'3" and weighs 215 pounds. He now has a chance to seize some playing time at 1B for the contending Astros, with neither Luis Valbuena nor Chris Carter doing much this year. Duffy is a decent hitter with some power, putting up 20 HRs this year while getting on base at a decent clip. His tools don't stand out, but he can play either 1B or 3B competently. His batting eye is decent (with this year's 0.53 mark an improvement over his 0.38 career batting eye), and he does not strike out excessively. His 16% strikeout rate this year is right in line with his 17% career mark. He had a great year, leading his team in hits and driving in 104 runs, leading to him being named the Pacific Coast League MVP. On an Astros team prone to the strikeout, Duffy could be a useful player to get on base or drive in a runner. Singleton is still around, but for now the team is giving this Matt Duffy a chance to show if he belongs. With a batting line this year nearly identical to his career mark, he could put up decent numbers. In five minor-league seasons Duffy has produced a batting line of .293/.367/.471 in 2194 AB. (NR)
2015 STATS: Fresno (AAA) – 490 AB, .294/.366/.484, 29 2b, 20 HR, 0.53 Eye, 4 SB

Jay Jackson (RHP, SD)
After being in the minors for eight years with five teams and stalling at the Triple-A level for the past seven seasons, 27-year-old Jay Jackson will make his major league debut out of the taxed San Diego bullpen. The 6'1", 195-pound righty is having his best season, so the team might as well see if he can handle the major leagues. Jackson was drafted by the Cubs back in 2008 as a starter, but has successfully transitioned into a late-inning reliever and had 15 saves this year between Double-A and Triple-A. Jackson features a low-90s mph fastball, but his secondary pitches (curve and change-up) haven't developed as hoped, yet in his bullpen role he's been successful enough. He hasn't given up too many home runs and has struck out nearly five times as many batters as he's walked this year. He might find a role in the majors as a middle reliever. In seven Triple-A seasons his ERA is 4.89 with a 1.456 WHIP and a Cmd of 2.3 in 596.1 IP. (NR)
2015 STATS: El Paso (AAA) – 48g, 63.2 IP, 2.54 ERA, 2.4 Ctl, 4.1 Cmd, 9.9 Dom, 2 HR, .239 oppBA
CURRENT ROLE: Middle reliever
POTENTIAL: Middle reliever

Cody Decker (1B/3B, SD)
After seven years in the minors, soon-to-be minor-league free agent and 2009 UCLA draftee Cody Decker has finally reached the big leagues. The 28-year-old 1B and 3B has put up moderate numbers in his career, and this season has seen even a step back from those numbers. So his cup of coffee is more of a token thank you to a player who is about to end his time with the team. The stocky 5'11", 225-pound infielder has no speed (five career stolen bases), but does bring power to the plate with 154 career home runs. He routinely puts up 20+ HR seasons, with an OBP that is decent if not great. Since he plays both corner infield spots, he can provide some useful pop off the bench while backing up more than one position. In seven minor-league seasons Decker has produced a batting line of .265/.348/.524 in 2566 AB. (NR)
2015 STATS: El Paso (AAA) – 373 AB, .252/.335/.448, 23 2b, 21 HR, 0.39 Eye, 1 SB
CURRENT ROLE: Bench infielder
POTENTIAL: Bench infielder
