1) Zach Phillips (LHP, Clinton) - A 20-year-old lefty, Phillips allowed just one total run between three starts in the last two weeks. Though he gave up four hits and walked three in five innings on Friday, he was able to keep his opponent off the board, earning his 10th win of the season. Phillips won just five games in 28 starts with Clinton in 2006. His ERA currently sits at 2.45.
2) Mauro Gomez (1B, Clinton) - Clinton's slick-fielding first baseman had been quiet with the bat up until his recent stretch. In his last 10 games, Gomez has gone 13-for-35 with two doubles and six home runs. He recently hit five home runs in five days and is hitting .393 in 56 July at-bats.
3) Edinson Volquez (RHP, Oklahoma) - Volquez fanned 10 while walking none in his final start with the Frisco RoughRiders before being promoted to Triple-A Oklahoma. In his first start of the season with the RedHawks, Volquez surrendered just one hit over seven innings of work. After a rough start to the season with Bakersfield, Volquez now appears to be on the fast track back to the Major Leagues.
4) Chris Davis (3B, Bakersfield) - Davis recently saw his hitting streak come to an end at a California League record-tying 35 games. He is 14-for-42 with two doubles and four homers since July 8. Davis, who was hitting .262 at the end of May, is currently batting .307.
5) Andy Walker (RHP, Bakersfield) - It has been a rough season for Ace Walker, but he has been phenomenal in his last three starts. The 24-year-old fanned 13 in a complete game, four-hit shutout on July 12. He was nearly as good in his last start, surrendering just two runs on four hits in seven innings. Though Walker is just 5-10 on the season, he is 3-1 in the month of July.
6) John Mayberry (RF, Frisco) - Mayberry has displayed impressive power since being promoted to Double-A Frisco. Although the Stanford product has only 10 hits over his last 11 games (.263), five of those hits have left the park. Mayberry, who has nine round-trippers with the RoughRiders, has combined for 25 home runs in 354 at-bats this season.
7) Taylor Teagarden (C/DH, Bakersfield) - Teagarden still isn't able to catch full-time because of his elbow troubles, but it hasn't hurt him at the plate. The Dallas native hit just .235 (8-for-34) over the last two weeks, but like Mayberry, half of his hits were home runs. The extremely patient catcher also drew 11 walks and knocked in 11 runs over the 11-game stretch. Teagarden leads the California League in on base percentage and is currently second in slugging percentage.
8) Jesse Ingram (RHP, Frisco) - Ingram loses points for pitching in just 4 2/3 innings, but it's hard to be more dominant than he has been. The Frisco closer hasn't allowed a hit in any of his five appearances over the last two weeks. He has walked just one while striking out 10. Ingram, who has recorded three saves in those five appearances, remains a perfect 20-for-20 in save opportunities this year. He has not allowed a run since June 10.
9) Jacob Brigham (RHP, Spokane) - Brigham is the lone short-season player to make to the hot list. The right-handed pitcher surrendered just one run on six hits in 11 2/3 innings over his last two starts. He has walked five and struck out 10. A sixth round pick in last year's draft, Brigham is 3-1 with a 1.78 ERA as a member of the Spokane Indians this season.
10) Luis Mendoza (RHP, Frisco) - Mendoza has been the workhorse of the Frisco staff this season, going 10-1 with three complete games while logging 101 1/3 innings. In his two appearances since July 8, the native of Mexico has yielded only one run in 13 combined innings. He has worked at least six innings in each of his last five starts.
1) John Whittleman (3B, Clinton) – Though Whittleman did hit a home run in the All-Star Futures Game, his work with the Clinton LumberKings has been less than impressive of late. The third baseman's average has dipped all the way to .274 after going 5-for-49 with only one extra base hit in July.
2) Fabio Castillo (RHP, Spokane) - One of the most talented pitchers in the Rangers organization, Castillo has struggled in his first season of professional ball in the U.S. The right-hander has surrendered five runs on 12 hits in six innings over his last two starts. He has walked six and struck out just two during that time. Castillo is being hit at a .343 clip through his first six starts of the season.
3) Chad Tracy (OF, Clinton) - A 22-year-old product of Pepperdine, Tracy has struggled ever since playing in the Midwest League All-Star Game. The left fielder is 16-for-93 (.172) with no home runs in 24 games since the All-Star break. Tracy, who is hitting .122 in his last 10 games, is batting just .252 on the season.
