This one isn't like the others. Seems like Oneli had some struggles in the DWL playoffs. At least is just 6 appearances.
In 18 appearances (22.0 IP), Perez (4-0, 1 save) has allowed 5 runs, 4 earned, on 7 hits while striking out 18 and walking 7. He has a 1.64 ERA.

If I'm reading licey's schedule correctly, oneli could get a few more chances there. BTW, here's MLB.com's update.
