According to the Arizona Republic's Nick Piecoro, Pollock was diagnosed with a sprain in his left thumb. Pollock will likely undergo an x-ray and MRI with a hand specialist on Tuesday, so we should know more soon on the severity of the injury.
Ryan Braun was out of the Milwaukee lineup for the second game in a row with back tightness. An All-Star in 2015, Pollock played only 12 games in 2016 after breaking his elbow on a slide just before the regular season started and was out from mid-May to early July with a strained groin last season. Jonathan Villar also hit a home run in the inning. The six-game losing streak is the team's longest under Lovullo. He helped the Brewers win for the fourth time in five games and the fifth time in seven. Junior Guerra tossed six innings of two-run ball to even his record at 3-and-3.
Christian Yelich singled in the go-ahead run in seventh inning as the Brewers went on to beat the Diamondbacks 7-2 in the first of three at Chase Field.
Jeff Mathis walked to open the eighth inning off Taylor Williams (0-1), and pinch runner Jarrod Dyson took second on a sacrifice bunt.
Arizona starter Zack Greinke gave up four hits and one run in six innings, with five strikeouts and one walk. The team recently got back right fielder Steven Souza Jr., who they acquired from Tampa Bay last offseason.
Shaw and Santana hit two-out drives in the first as Milwaukee took a 3-0 lead, but Descalso homered in the bottom half.
