Dontrelle Willis is Still Valuable

Mar 21, 12 Dontrelle Willis is Still Valuable

Just days after being released by the Philadelphia Phillies this spring, Dontrelle Willis signed a minor league deal with Baltimore Orioles. You may be wondering why teams keep signing Willis, who has been with six teams (Tigers, Giants, Diamondbacks, Reds, Phillies, and Orioles) since 2010. I wonder the same because all of these teams (with minor exception to the Giants) did not try Dontrelle out as a lefty specialist in the bullpen – he continues to be placed in the rotation, where he has been atrocious since 2007.

Here is why Dontrelle Willis is valuable if he is used exclusively as a lefty specialist.

Take a look at Dontrelle Willis‘ splits for key statistics in 75.2 innings last year and in his career as a whole underneath. The main numbers that pop out are his BAA (Batting Average Against) and K/9. Lefty batters have hit just .196 against Willis throughout his career, while RHBs have hit a respectable .276. Even more astounding – Willis’ strike out rate for LHBs is nearly doubled that of RHBs in his career (10.5 K/9 vs 5.72 K/9).

BAA vs L BAA vs R K/9 vs L K/9 vs R Strike% vs L Strike% vs R GB% vs L GB% vs R
2011 .123 .298 10.59 5.68 71.10% 60.60% 58.30% 53.80%
Career .196 .276 10.5 5.72 65.70% 61.10% 51.0% 45.0%


Two reasons for his success vs LHBs: 1) He throws strikes significantly more often to LHBs than he does to RHBs and 2) He induces ground-balls more often vs LHBs than he does vs RHBs.

Even though Willis has lost his overpowering velocity, he is able to succeed vs LHBs because of his off-speed pitches (slider and curve) which he has become more reliant on in recent years.

Another interesting note is Willis’ swinging strike percentage, which jumped up to 15% last year – the first time it reached such high margin since leaving the Marlins.

If Baltimore puts Dontrelle in the bullpen as a lefty specialist, the team will have a valuable asset.

    Имеется такая услуга – добровольное медицинское обслуживание (или ДМО).
    Она предполагает, что вы вносите небольшую сумму за то, что посещает врачей в течение года не платя за каждый прием.
    Однако опросы показывают, что лишь 3% жителей города знают о такой услуге.
    Да потому что клиникам выгоднее брать плату за каждый визит.
    А если какой-нибудь сотрудник клиники попытается рассказать про добровольное медицинское обслуживание клиенту – это сулит ему увольнением.
    Эта информация уже спровоцировала много скандалов, после того как информацию об этом рассекретил один возмущенный врач.
    Его уволили “по собственному желанию”, после того, как он посоветовал ДМО своему пациенту.
    Самое страшное, что официальные положения по ДМО есть в открытом доступе, просто находили на эту информацию только случайные люди.
    Как отстоять свои права?
    О правилах оказания услуги и обязанностях частных клиник можно узнать, просто вбив в Яндекс фразу: “добровольное медицинское обслуживание”.
    Именно обслуживание, а не страхование.
