Chicago Cubs catching prospect Moises Ballesteros went 4-for-5 with a double and two home runs during their contest against Triple-A St. Paul on Wednesday. These were Ballesteros' first two long balls of the Triple-A regular season. During this impressive six-game hitting streak, the young backstop has posted a stellar .522/.577/.870 slash line. Through the first 14 games of the Iowa Cubs' regular season, the 21-year-old has swung a hot bat, holding a .379/.419/.586 slash line. Last summer, Ballesteros received his first taste of Triple-A and enjoyed similar production as he posted a .281/.340/.454 line with 15 doubles and 10 home runs across 68 games. Fantasy managers should expect the No. 66-ranked prospect in baseball to debut later this summer.

San Diego Padres relief pitcher Robert Suarez earned his MLB-leading eighth save of the season on Wednesday night against the Cubs to secure the series win over Chicago. Suarez retired the side in order on just eight pitches, preserving a 4-2 victory. Suarez has been absolutely dominant this season, allowing just three hits and two walks across nine scoreless innings. He has 10 strikeouts in nine games and has converted each of his eight save opportunities. The Padres lead the MLB with 15 wins, and Suarez is one of many things that have gone right for them. The 34-year-old righty remains one of the elite closers in baseball right now.

Baltimore Orioles third base prospect Coby Mayo went 3-for-5 with a double, a home run, and three RBI during their contest against Triple-A Omaha on Wednesday. This was Mayo's second three-hit game of the young season. In addition, the top third base prospect has begun to find his power as he has gone deep three times over his previous four contests. Over his last nine contests, Mayo has tallied at least one hit in all but one contest. During this stretch, the 23-year-old has posted a stellar .343/.442/.714 slash line with seven extra-base hits. Mayo reached the majors last summer but tallied just four hits across his 17-game stint. Fantasy managers should expect Mayo to contend for an early return to the big leagues if he continues to perform well at Norfolk.

Seattle Mariners relief pitcher Andres Munoz has already racked up seven saves in his team's nine wins this season. He pitched a clean ninth inning against the Reds in Cincinnati to secure the 5-3 win. He didn't give up a hit or run but did need 19 pitches to get through the inning. The 26-year-old righty has appeared in nine games for the Mariners this year, allowing only five hits and racking up 12 strikeouts in nine scoreless innings. He'll continue to be one of the top closers in baseball since his team plays so many close games, and he is so effective closing them out. The Mariners finish their series in Cincy on Thursday afternoon.

Boston Red Sox relief pitcher Justin Slaten slammed the door on the Rays in the ninth to earn his second save of the season. Slaten got the call from manager Alex Cora with Aroldis Chapman unavailable after pitching three of the last four nights. He retired the heart of the Rays order with a one-run lead, getting Junior Caminero to fly out to center field before striking out Christopher Morel and Jose Caballero to end the game. Slaten had one rough outing against the Orioles, giving up four runs without retiring an out. However, aside from that outing, he has not allowed a run in his eight games, earning a save in both of his chances and retiring the side in order in each of his last four innings. He will continue to sneak a save whenever Chapman isn't available, but Chapman is still Boston's closer of choice for now.
