Billy Butler’s ISO was up over 100 points in the second half before his home run on Sunday. His GB/FB is down to 1.28 from 2.12. He will come cheap next year and possibly bounce back to his peak form.
According to the stats at minorleaguecentral.com 42.9% of Javier Baez’ outfield fly balls have become home runs. His rate in Triple-A was 23.2%. In the majors only Jose Abreu and George Springer are above 40% with a meaningful number of plate appearances.
Pedro Alvarez’ BB/K is all the way down to 0.06 in August. After a brief benching he is playing enough to be rostered, but despite two home runs on Saturday not well enough to be counted on.
Shin-Soo Choo’s batting eye is also deteriorating. He owns a 0.16 BB/K in the second half. He hits right-handed pitching to the tune of 148 wRC+ in his career but only 104 this year. BABIP is not to blame, it sits right at .300.
Clayton Kershaw has the only single season SIERA below 2.00 since 2010.
With a 99 wRC+ Dustin Ackley is nearly a league average hitter. He ranks 19th as a 2B and 31st as a MI but loses that eligibility this year. He is not relevant in standard mixers next year, but AL only players should note his progress.
Tsuyoshi Wada has a 41/11 K/BB and 3.60 xFIP through eight starts. He is a solid streaming candidate in September.
With Manny Machado out for the year Steve Pearce is a starter again. He owns a 143 wRC+, sixth among first basemen with 250 PA.
Hector Rondon recorded his eighth straight scoreless appearance on Sunday and has a 2.74 xFIP. Chicago should have no urgency to replace him next year.
Kennys Vargas is showing legit power with a .202 ISO but there are some troublesome markers as well. He has a 0.16 BB/K and a .424 BABIP propping his average up. A .333 BABIP on ground balls is highly suspect given his 1.9 speed score. On the positive side his spray chart reveals he is not an obvious shift candidate.
Rougned Odor is struggling in many ways as a 20-year-old in the majors, but it should all be taken in context. His .373 SLG exceeds Dustin Pedroia’s .372.
