Abreu was on fire all month, hitting .313 with 10 homers and six doubles. He currently leads the American League with 26 home runs and a .627 slugging percentage, good for a 155 wRC+ and 2.7 fWAR through 72 games. The 27 year old has certainly been worth every penny the White Sox paid for him, justifying the six-year, $68 million contract he received after defecting from Cuba.
Hamilton hit .327 with 10 doubles, three homers, and 14 stolen bases in June, helping overcome a slow early start and moving his season line up to .279/.309/.400 with 35 steals and 2.8 fWAR. His production has been on an upward course as the season progresses: .610 OPS in April, .652 in May, .842 in June. His outfield defense has been quite good according to the advanced metrics, which is why his fWAR is actually a little higher than Abreu's.
