Braves second base prospect Tommy La Stella went 3-for-4 with a walk for Triple-A Gwinnett on Saturday, and is hitting .295/.370/.318 for the season
With Dan Uggla hitting .237/.281/.390 for Atlanta, La Stella will remain in Triple-A until Uggla's OPS dips below .650. The 25-year old second baseman is not likely to become an elite player, but he could do much better than Uggla (who still has one year and $13 million left on his contract).
Yankees placed RHP Ivan Nova on the 15-day disabled list with a partially torn ulnar collateral ligament.
Nova hasn't decided whether he'll rest and rehab or undergo Tommy John surgery, but the latter is probably an inevitability. It's a tough blow for the Yankees' rotation, as Nova showed glimpses of a potential breakout last season. The Yankees will likely use Vidal Nuno as his rotation replacement for now.
Mets manager Terry Collins said Sunday that Kyle Farnsworth has supplanted Jose Valverde as the team's new closer.
Farnsworth has pitched well for the Mets in the early going, allowing just one run over his first 7 1/3 relief innings. However, his velocity has been declining for a few years now and he hasn't had an effective full season since 2011. It's a move that's unlikely to work out, but the Mets don't have any great options.
Diamondbacks outfield prospect Brandon Jacobs went 2-for-3 with a double and two walks on Saturday for High-A Visalia.
He is hitting .271/.340/.479 with three home runs and a double on the season in his return to High-A. Jacobs is a tremendous athlete who has struggled to turn his athletic ability into baseball production. After a breakout 2011, he struggled for the next two seasons, which included getting traded twice (from the Red Sox to the White Sox to the Diamondbacks) in a five month span in 2013. If he can cut down on his strikeouts, he could turn into a middle of the order force with 25-plus home run potential.
Brendan Ryan (back) was limited to six at-bats during a simulated game Saturday due to a tight hamstring.
Ryan was playing in his first game since March 4. Yankees manager Joe Girardi said it was "a little bit" of a setback for the infielder and seemed skeptical Ryan would be activated by the end of next week as originally hoped. "I don't know now," Girardi said. "We'll see how he feels next week. For that to happen, we'd have to push him a little bit. But we'll see."
Yankees recalled RHP Bryan Mitchell from Double-A Trenton.
Mitchell held a 5.14 ERA but struck out 20 over his first 14 Double-A frames. He'll give the Yankees some length in the bullpen with Vidal Nuno making a spot start Sunday.
Yankees recalled RHP Preston Claiborne from Triple-A Scranton/Wilkes-Barre.
Claiborne allowed just one earned run over his first six relief innings at Triple-A to earn the promotion. He'll work in middle relief.
Red Sox prospect second baseman Mookie Betts went 4-for-5 with his second home run of the season for Double-A Portland.
The 21-year old Betts is hitting .453/.492/.717 for the season, with four stolen bases to go with five walks and seven strikeouts. The slugging percentage is much higher than the 5'9" 160-pound Betts will achieve in the major leagues, but hitting .300 with 30-plus stolen bases is not out of the question. He's still blocked in Boston, but could be a big chip in a trade or be a solid fill-in if there is an injury, such as a recurrence of Dustin Pedroia's wrist injury.
