Mariners activated RHP Robert Whalen from the 10-day disabled list; optioned him to Triple-A Tacoma.
Whalen is recovered from his spring calf strain, but there's not a spot for him right now at the major league level. He'll work as a starter at Tacoma.
Pirates prospect Will Craig knocked in five runs on Wednesday for High-A Bradenton.
RBI aren't a great predictive stat for prospects, but it certainly isn't a bad thing to see. Craig also went 2-for-4 with a double, a run and a strikeout. Pittsburgh took Craig in the first-round last year with the hope that his bat could move quickly through the system. So far, so good.
Jeff Locke (biceps) has been pitching simulated games in Jupiter, Florida.
And if everything continues to go smoothly the left-hander should soon be cleared for a minor league rehab assignment. Locke has been out all season because of tendinitis in his left biceps. "I know he's feeling good," manager Don Mattingly told MLB.com on Thursday. "Not one report I've read that he's had any negative effect to what he's doing. He's really getting closer."
Braves prospect Ronald Acuna went 2-for-4 with a double for High-A Florida on Wednesday.
Acuna also knocked in three runs, scored two runs, stole two bases and walked once. That's a full afternoon for anyone. We're several years away from seeing him in the big leagues, but this is one of the most talented outfielders in baseball. He should already be on your roster in deep keeper leagues.
Red Sox transferred RHP Carson Smith from the 10-day disabled list to the 60-day disabled list.
The move clears a 40-man roster spot for infielder Chase d'Arnaud, who was claimed off waivers from the Braves on Thursday. Smith is still working his way back from Tommy John reconstructive elbow surgery. He should be ready sometime in June.
Red Sox claimed INF Chase d'Arnaud off waivers from the Braves.
He was designated for assignment by Atlanta on Tuesday. The 30-year-old infielder holds a weak .231/.288/.312 career batting line at the major league level.
Yankees prospect Jorge Mateo went 3-for-5 on Wednesday for High-A Tampa.
Mateo also scored two runs. It was a much needed quality game for the infielder, as even with the three-hit day his average still sits at .234. All of the talent is here to be a fantasy stalwart, but the application of those talents has taken a hit in the last few years. He might need a change of scenery.
Reds prospect Vladimir Gutierrez pitched five shutout innings for High-A Daytona on Thursday.
It was easily the best start of Gutierrez's season, as he allowed just three hits and seven strikeouts with no walks. There's a long way to go, but when he's at his best he shows a 96 mph fastball and a true power curveball that can miss bats. If the command can be even average, he has a chance to pitch in a rotation. If not, he could be a quality relief option.
