Mariners 3B prospect D.J. Peterson went 2-for-4 with a double and a walk for Double-A Jackson on Friday, raising his Double-A line to .290/.333/.500.
After a slow start, Peterson is in the midst of a seven-game hitting streak during which he has hit .367/.406/.733 with two doubles and three home runs. He has the potential to be a middle of the order slugger who hits 20-plus home runs on an annual basis since Raul Ibanez in the mid-2000s. Peterson will likely spend the rest of the season in Jackson, and should be playing for the Mariners at some point in 2015.
Cubs prospect first baseman Dan Vogelbach went 2-for-5 with a double for High-A Daytona on Friday, raising his season line to .274/.362/.427.
After a great June in which he hit .319/.429/.553 with 10 doubles and four home runs, Vogelbach has struggled in July, hitting .226/.316/.290 with two doubles over nine games. For the season, he has hit a robust .311/.391/.519 against right-handed pitching but just .198/.302/.238 against lefties. Due to his defensive limitations (his natural defensive position is DH), he may end up as a left-handed bat off the bench or a part of a platoon.
Indians recalled Zach McAllister from Triple-A Columbus.
He will return to the Indians rotation on Saturday against the White Sox, taking the place of the injured Justin Masterson. He owns a 5.89 ERA, 1.52 WHIP and 43/19 K/BB ratio over 47 1/3 innings with the Tribe this season.
Pirates shortstop prospect JaCoby Jones went 1-for-3 for Low-A West Virginia on Friday, extending his hitting streak to 13 games.
Jones has hit .500/.528/.917 with two doubles and six home runs during his hitting streak, and is hitting .297/.363/.493 with 14 doubles, one triple, and 14 home runs for the season. Like many young hitters, he needs to work on his pitch recognition and make more consistent contact, but he has the talent to be a solid shortstop who hits for some power and steals bases.
Indians optioned RHP Vinnie Pestano to Triple-A Columbus.
He has struggled in his limited time with the Indians this season, posting a 5.00 ERA, 1.56 WHIP and .333 batting average against over his first nine innings. He'll surely return at some point after the All-Star break.
Marlins third base prospect Colin Moran went 3-for-4 with a double for High-A Jupiter on Friday, raising his season line to .303/.347/.408.
Moran's big day brought his batting average above the magical .300 mark for the first time since going 2-for-4 in the first game of the season. After hitting .337/.376/.485 in June, Moran has remained hot in July, hitting .342/.390/.421. Moran could be in line for a promotion to Double-A Jacksonville before the end of the season, and could be manning the hot corner in Miami as soon as mid-2015.
Braves prospect right-handed pitcher Cody Martin allowed eight hits, six walks, and six runs over five innings for Triple-A Gwinnett on Friday.
Martin only struck out three batters in what was likely his worst outing of the season. The 24-year old was the Braves 7th round pick in the 2011 draft and has the potential to be a back-end starter who logs innings. After a solid April, opposing batters have been hitting .282/.346/.442 off Martin.
Astros right-handed pitching prospect Vincent Velasquez struck out four and allowed one single in two innings during a rehab start with the rookie-level GCL Astros on Friday.
Velasquez has missed two months with a groin injury, so it is good to see him back on the mound. He has the potential to be a solid mid-rotation starter, but he missed all of 2011 after having Tommy John surgery, which has slowed his development. He has a low-to-mid-90s fastball and a great change-up, and could be part of the Astros rotation as soon as late-2015.
