Phillies RHP prospect Mark Leiter didn't allow a hit until the seventh inning Sunday in a no-decision for Double-A Reading.
New Hampshire eventually broke through for three hits and three runs in the seventh, but it was still a fine outing for the 25-year-old, who now holds a 6-3 record over 22 appearances for the Fightin Phils. He totaled four strikeouts while yielding just two free passes. Opponents have hit .241 against Leiter this year with 85 strikeouts in 357 at-bats. The former 22nd-round pick is the nephew of former Mets left-hander Al Leiter.
Diamondbacks RHP prospect Max Duval fanned six hitters over a career-high eight scoreless innings Sunday in a win for Low-A Kane County.
He held visiting Beloit to four hits while spinning 72 of his 99 pitches for strikes. The victory snapped a three-game losing streak for the 25-year-old. Duval has been very well-traveled this year, appearing in games for Kane County, High-A Visalia, Short-Season Hillsboro and even the team's Arizona League affiliate. The results have mostly been solid for Duval, who carries a 3.55 ERA over 14 outings (11 starts) in 2016.
Athletics activated DH Billy Butler from the 7-day concussion disabled list.
Butler suffered a concussion last weekend in a clubhouse fight with teammate Danny Valencia. The two have since apologized, to each other and to the A's organization. Butler has a disappointing .286/.338/.419 batting line with four homers and 30 RBI in 228 plate appearances this season.
Athletics optioned INF/OF Arismendy Alcantara to High-A Stockton.
The move clears a 25-man roster spot for Billy Butler, who was activated off the 7-day concussion disabled list in a corresponding move. Alcantara is 3-for-15 with eight strikeouts this season in the major leagues.
Cardinals recalled LHP Dean Kiekhefer from Triple-A Memphis.
