Jarrett Parker seems to be in that stage of baseball prospect life where some may label him as a "AAAA" player, meaning he rakes in Triple-A but can't seem to find a rhythm in the major leagues. Aside from his three home run outburst last season, Parker has been mostly a disappointment for the Giants. The main reason is the amount of times Parker strikes out. In 87 major league plate appearances, he has received a "K" 30 times, which is an astoundingly high 34.5 percent rate. But despite batting .226 so far in 2016, his career big league average is right at .300, including .613 slugging percentage.
That's not even close to what Parker is doing this year in Sacramento. Before being called back up to San Francisco to replace an ailing Angel Pagan, Parker hit a ridiculous 11 home runs in May. Even more remarkable is that it came in just 98 plate appearances. So he hit a dinger 11.2 percent of the time he stepped into the batter's box. It all equated to a .954 slugging percentage in May, which of course makes him Giant Potential's "Prospect of the Month."
Some, actually most players need consistent playing time to really prove their worth in the majors. During the nine-game stretch from September 25 to the end of the season in 2015 when Parker started almost every game, he slashed .367/.441/.800 with a double and four home runs. But he was still striking out a ton. With both Pagan and Hunter Pence on the disabled list, Parker will have another chance to get consistent at-bats. Let's hope he can lay off pitches out of the strike zone.
Meanwhile, here's a look at the best Giants' minor leaguer at each position during the month of May.
C, Matt Winn
It's been a down year so far for catchers in the Giants' system. Andrew Susac is just getting healthy again and Aramis Garcia took a knee to the face sliding into second base and will probably miss the rest of the season with facial fractures. Thankfully Buster Posey exists. The most promising catcher in the system in May was Richmond, Va. native Matt Winn, who hit four homers and five doubles over the course of 23 games for the Augusta GreenJackets. He'll look to bring his strikeout rate down in the coming months, having K'ed 29 times in 95 plate appearances.
May Stats: .241/.290/.460, 21 H, 5 2B, 1 3B, 4 HR, 13 RBI, 5 BB, 29 K, 30.5 K%
1B, Chris Shaw
There's absolutely no doubt who the best first baseman prospect is right now for San Francisco. Chris Shaw is doing what everyone expected and hoped he would do in the California League through the first two months. In May, his numbers took a "dip" but only because he destroyed the ball in April. Still, he came into June leading the league with 18 doubles and slugging percentage at .605. His wOBA currently sits at .416, which is more than excellent and a top-40 mark in all of the minor leagues.
May Stats: .286/.361/.590, 30 H, 8 2B, 8 HR, 26 RBI, 12 BB, 25 K, 21.0 K%
2B, Jalen Miller
Jalen Miller improved immensely from April to May, clearly needing some time to get acclimated to the South Atlantic League at his young age. At 19, he is 2.3 years below the league average. He raised his average a full 51 points with 30 hits, including five doubles and three triples, in May while playing exclusively second base. He made seven errors during the course of that time, but only two since May 12.
May Stats: .313/.330/.458, 30 H, 5 2B, 3 3B, 1 HR, 17 RBI, 4 BB, 19 K, 18.1 K%
SS, C.J. Hinojosa
The former UT-Austin ball player made it back-to-back fantastic months of offensive baseball for the San Jose Giants, proving Giants personnel right with their advanced assignment of the shortstop. C.J. Hinojosa skipped right over Class-A Augusta and has been among the league leaders in multiple categories. He leads the California League in on-base percentage, is second in batting average, and third in OPS, while leading the organization with a .417 wOBA. Hinojosa collected 32 hits in May, tied for second best in the Giants' system, while drawing more walks than strikeouts. After committing six errors in April, Hinojosa toned it down to just two in May.
May Stats: .320/.402/.490, 32 H, 7 2B, 2 3B, 2 HR, 13 RBI, 15 BB, 13 K, 11.0 K%
3B, Mitch Delfino
Welcome back, Mitch! This former Cal Bear missed most of April with a two separate DL stints but has been a regular at third base since May 3. He hit a lot of singles, 21 of them to be exact, in what was certainly not his best display of power. But still, his .321 average and .404 on-base percentage made up for his relatively low .423 slugging mark. Delfino doesn't have crazy power, but he did hit 13 home runs in Augusta in 2013 and 12 with San Jose in 2014. He is slugging .381 so far this year, which is actually right near his career average of .382.
May Stats: .321/.404/.423, 25 H, 2 2B, 2 HR, 10 RBI, 11 BB, 13 K, 14.6 K%
OF, Steven Duggar
Like Hinojosa, Steven Duggar finished May drawing more walks than strikeouts. He leads the organization with 33 walks so far in 2016, and sprayed the ball all over the yard this past month, collecting 11 extra-base hits among 30 total. He and Jalen Miller lead the system with four triples, three of which Duggar had in May alone. Duggar's outfield arm is on full display, recording seven outfield assists already just 44 games in.
May Stats: .300/.410/.500, 30 H, 5 2B, 3 3B, 3 HR, 14 RBI, 20 BB, 19 K, 15.6 K%
OF, Austin Slater
Austin Slater managed to mash his way out of the Eastern League into Triple-A ball after just 95 career games in Double-A. At age 23, Slater is 3.7 years younger than the Pacific Coast League average. He is one of 37 23-year-olds in the PCL, while there are just 15 players younger than 23. He took May by storm for the Richmond Flying Squirrels with 30 hits, including seven doubles and three home runs, all while striking out just 17 percent of the time and drawing 14 walks. He led the league in OPS during the month of May before being promoted to Sacramento. He's also played a perfect outfield so far in 2016, making zero errors while playing mostly center field.
May Stats: .411/.494/.658, 30 H, 7 2B, 1 3B, 3 HR, 16 RBI, 14 BB, 15 K, 16.8 K%
OF, Jarrett Parker
I think the numbers speak for themselves. When you hit 11 home runs in fewer than 100 plate appearances, you're clearly on to something. When he was called up to the Giants on May 23, Parker led all of the minor leagues with 13 home runs. Only Chris Shaw had more RBI than Parker in May.
May Stats: .400/.473/.954, 26 H, 1 2B, 1 3B, 11 HR, 21 RBI, 7 BB, 11 K, 15.1 K%
DH, Miguel Gomez
A special category had to be created for Miguel Gomez. I had previously not included a category for designated hitter, because most players get a decent amount of looks at a position. But Gomez, during 27 May games, was DH 18 times. He played first base fives times and third base four times, so it was hard to throw him into any of those categories. I guess that's all beside the point, though. Gomez's 34 hits in the month were two more than any other Giants minor leaguer, and his 10.5 percent strikeout rate was the lowest in organization. He struck out just 12 times in 114 plate appearances, while drawing seven walks and hitting eight doubles and three home runs. He's rocking a nice .382 wOBA through June 3, which is seventh best in the system.
May Stats: .324/.372/.486, 34 H, 8 2B, 3 HR, 14 RBI, 7 BB, 12 K, 10.5 K%
RHP, Cory Taylor
On to the pitchers, where Cory Taylor squeaked out a stampede of impressive starting pitching performances from right-handers in May. I gave the nod to Taylor by virtue of his stellar K/BB ratio (4.17) combined with his 1.40 ERA and .212 opponent batting average. Hitters slugged just .253 off Taylor in May, and have a .280 mark overall, which is made up of just four extra-base hits among 43 total hits in 46.1 innings.
May Stats: 4 GS, 1.40 ERA, 1.052 WHIP, 25.2 IP, 21 H, 6 BB, 25 K, .212 OBA
RHP, Rodolfo Martinez
This was another difficult category, knowing that Tyler Rogers still hasn't allowed an earned run in 2016 and Reyes Moronta struck out 18 in 13 innings while giving up just six hits. But I went with Rodolfo Martinez because closers are important, and he locked down 10 saves in 10 tries. His pitching this year earned him a brand new spot on MLB Pipeline's Top-30 Giants' list when Derek Law "graduated" from the ranks. Martinez struck out a batter an inning and kept his ERA and WHIP below 1.00. That's really good, not to mention he's got the highest fastball velocity in the system besides Ray Black.
May Stats: 14 G, 10 SV, 0.64 ERA, 0.929 WHIP, 14 IP, 9 H, 4 BB, 14 K, .180 OBA
LHP, Adalberto Mejia
There was no question about this one. Adalberto Mejia left a rough April in the dust and absolutely dealt in May. He finished the month nearly throwing a complete game shutout, but was pulled with one out left after reaching 104 pitches. He struck out 10 in the game, while allowing just four hits and one walk. Overall, he made five starts, totaling 36.2 innings, and surrendered just 23 hits — an average of 5.6 per nine innings. And only five runs crossed home plate under Mejia's watch, two of which were unearned, giving him a 0.74 ERA. It helped lower his season mark to 1.87, which is tied for third best in the Eastern League.
May Stats: 5 GS, 0.74 ERA, 0.818 WHIP, 36.2 IP, 23 H, 7 BB, 28 K, .178 OBA
LHP, Alex Torres
It was kind of a rough month for left-handed relievers in the system, too. Caleb Smith impressed with a nice 11.4 K/9 ratio but his ERA and WHIP were higher than that of Alex Torres. While not really a prospect, Torres has been pitching quite well for the Sacramento River Cats and could find himself on the Giants should injuries present themselves. In May, he allowed just two earned runs in 9.1 innings while striking out 11. Over the entire season, opposing hitters are batting a measly .167 off Torres, with the splits not currently labeling him as a "lefty specialist" considering right-handers have just five hits off Torres in 32 plate appearances.
