That resulted in the MLBPipeline.com First-Half All-Prospect team listed below. The only requirement for a player to be considered is that he was on a team Top 20 Prospects list at the start of the 2014 season. Some have graduated off those lists to the big leagues, with their strong performances at the highest level a major reason for their inclusion. All stats mentioned are through June 30.
1B: C.J. Cron, Angels
The former first-rounder bounced back from a so-so 2013 season to hit .319/.369/.602 in 28 Triple-A games, earning a callup to the big leagues. He hit eight homers and drive in 22 runs over his first 42 games for the Angels.
2B: Mookie Betts, Red Sox
Sure, he's playing outfield now, but that's just been to get his bat in the big league lineup. Betts hit .355/.443/.551 with 22 steals in Double-A to earn a promotion to Triple-A, where he promptly hit .322/.425/.444 in 23 games to earn the bump to Boston.
SS: Corey Seager, Dodgers
Yes, it's the California League, but it's hard not to be impressed by the 2012 first-round pick's numbers: .347/.401/.611 with 14 homers and 55 RBIs all while playing a solid shortstop. He was third in the Minors in total bases through the season's first three months.
3B: Kris Bryant, Cubs
About as big of a no-brainer as there is on this list, Bryant hit .352/.451/.717 with 28 homers and 73 RBIs while earning a promotion from Double-A to Triple-A, all in his first full season of pro ball.
C: Blake Swihart, Red Sox
The catching group didn't perform exceedingly well, but Swihart has handled himself well in his first taste of Double-A, hitting .296/.348/.482 with nine homers and 42 RBIs in 66 games. He's also thrown out better than 50 percent of would-be basestealers.
OF: George Springer, Astros
He needed just 13 games in Triple-A to prove he was ready, hitting .353/.459/.647 with three homers and four steals. He's provided a huge boost in Houston, with Springer finishing the end of June with 16 homers, 43 RBIs and three steals.
OF: Gregory Polanco, Pirates
Another callup who's given a big league team a lift, Polanco was hitting .347/.405/.540 with 15 steals when he was summoned to join Pittsburgh. He hit .288/.374/.375 with a pair of homers, 10 RBIs and four steals in 19 June contests following the promotion.
OF: Joc Pederson, Dodgers
In another organization, Pederson probably would have earned a big league callup by now. All he did in Triple-A was hit .319/.437/.568 with 17 homers and 20 steals, and that was with missing the last handful of games in June with a shoulder injury.
DH: Joey Gallo, Rangers
Gallo's first half, along with Bryant's presence at third, necessitated a DH spot. The Rangers prospect trailed only Bryant in total bases in the Minors. He did top the list with 29 homers, driving in 71 runs and hitting a robust .313/.443/.726, earning a promotion to Double-A in the process.
RHP: Jimmy Nelson, Brewers
Many of the "bigger names" have either been hurt or underperformed, but it'd be tough to find a right-hander who's been better than Nelson. In 15 appearances, Nelson went 9-2 with a 1.66 ERA. Over 97 1/3 innings, Nelson allowed just 62 hits (.180 average against) and 29 walks while striking out 105. That doesn't include his strong start for Milwaukee in late May.
LHP: Henry Owens, Red Sox
Owens continues to be one of the tougher southpaws to hit, going 10-3 with a 2.25 ERA over 15 starts in the Double-A Eastern League. Over 92 innings, Owens allowed 59 hits (.181 average against) and 37 walks while striking out 95. He gave up no runs in seven of those outings.
RP: Shae Simmons, Braves
Simmons was about as dominant as possible in Double-A during this season's first half, going a perfect 14-for-14 in save opportunities, holding hitters to a .183 batting average, posting a 0.78 ERA and striking out 11.7 per nine in 23 innings. It carried over to Atlanta, as the undersized right-hander gave up just two runs and struck out 13 over his first 13 big league innings.
