I know catching can be tough on the body, but Salvador Perez just turned 28! Sure, but his OBP just turned .259 .... he's a home run, low OBP guy, and now he's not even slugging .400 - I'm absolutely not buying without a significant paydown. Hey, Perez is worth checking on at this point as his value is down. He had a terrible month of June but he slugged .441 in April, .482 in May, and .491 so far in July. He's averaged 23 HR in the past 3 seasons and he's on pace for that or more this year. As for Duffy, I still think he'd be the ace on this Brewer staff, is under fairly reasonable control through 2021, and is still under 30. He's got 8 straight starts of at least 6 innings, with 6 of those 8 allowing one run or less. In that time, he ERA has gone from 5.81 to 4.40.
