As we head into the final day of June, the story of this month has mostly been written. There were some memorable performances during the past 29 days, and fantasy baseball managers who understand the advanced stats behind these performances can make smart moves in the coming days. Let’s take a look at some June stars.
June stat line: 9 HR, 19 R, 28 RBI, .418 AVG
Alvarez has been baseball’s best hitter in June, posting a 1.345 OPS that led the league by a wide margin. And any fantasy manager who looks at advanced stats could have seen this coming. Alvarez was good during April and May, but his performance was still unlucky based on the incredible batted-ball data he produced in those months. His luck finally normalized in June, and the results were spectacular. On the season, Alvarez now owns a .365 xBA, a .499 xwOBA and a 61.1 percent hard-hit rate.
Fantasy strategy: All Alvarez managers should resist the urge to sell high on him, and thankfully he seems to have avoided serious injury in a scary collision on Wednesday. In the words of Yahoo colleague Scott Pianowski, I would need a true Godfather offer to trade Alvarez. He could be the No. 1 fantasy asset in the second half of the season.
Jon Berti (2B/3B/OF, Miami Marlins)
June stat line: 15 R, 10 RBI, 18 SB, .297 AVG
Without a doubt, the month of June will be best remembered in fantasy circles for Berti’s wild stolen base total. The speedster has teased managers with his wheels in the past, but he has never put together a month like this. Berti entered June with just four swipes and was sitting on waivers in most fantasy leagues. He is now 78 percent rostered, and my guess is that the leagues where he remains on waivers are mostly points formats with a shallow number of teams.
Fantasy strategy: Berti managers should send him out in offers to every steals-needy team right away. There is a good chance that he has…
