Oakland Athletics Season in Review: Biggest Surprises and Letdowns

Bullpen Pillars Struggle
Blake Treinen, Lou Trivino and Joakim Soria played hot potato with being awful for most of the season, culminating with Treinen and Trivino doing next-to-nothing for the final month of the regular season after Puk and Luzardo debuted before being shut down.
Soria figured it out, going 7.2 scoreless innings in September with a .094 OPS allowed, but the Two T’s didn’t have the same luck.
From May 13 on, Lou Trivino had a 6.97 ERA and 2.13 WHIP while allowing an .870 OPS and .352 BAbip in 41.1 IP.
From April 28 on, Blake Treinen posted a 6.15 ERA and 1.74 WHIP while allowing an .852 OPS and .321 BAbip in 45.1 IP.
Somehow, the A’s were still 33-13 in Blake Treinen’s appearances in that span, incl. 16-2 in May and June.
The nature of rotating relievers in baseball make this not as much of a surprise as a disappointment, considering how stellar Treinen was last year – even earning Cy Young and MVP votes – and Trinvio’s dominant outing in the Wild Card Game.
If both Treinen and Trivino are on the team next season it would be a shocker.
