Maybe I put too much emphasis in swinging strike rate (swinging strikes divided by number of pitches), but I look at it as a good measure of dominance, and dominance in theory should lead to wins, strikeouts and a low ERA, though clearly that doesn't always happen. Either way, this week we'll look at the pitchers who have shown the greatest swinging strike rate growth in the second half and those who have regressed the most. A lot of these guys won't be on your waiver wire, and most leagues don't allow trades this late in the year, but at least it can help you look to set your weekly lineups and think about 2020.
Lopez has to be one of my more frustrating pitchers, probably because I own him in multiple dynasty leagues and formats (Strat even). Case in point, his last two outings:
September 5 at CLE: 9 IP, 1 H, 1 ER, 3 BB, 11 K
August 31 at ATL: 0.2 IP, 6 H, 6 ER, 1 BB, 0 K
Reynaldo Lopez has a 4.18 ERA in his last six starts, which is fine, but in two starts he allowed 5+
