The 33-year-old Janssen didn’t pick a great time to have his worst season since 2009, and his new agents will be tasked with convincing interested parties that this year was an aberration as opposed to a genuine cause for concern. The former Jim McDowell client opened the year on the disabled list with a back strain that sidelined him through mid-May. Janssen’s struggles began after the All-Star break — during which he caught a violent case of food poisoning and lost eight pounds as a result. As John Lott wrote in the National Post in late August, Janssen himself would not use his illness as an excuse, but he did make five appearances in an eight-game stretch just starting on July 20, when he’d spent the previous two days attached to an IV to get fluids back into his body.
The end result of Janssen’s season was a 3.94 ERA with 5.5 K/9 and 1.4 BB/9, but the first- and second-half splits are eye-catching. He allowed three runs in 22 innings with a 14-to-1 K/BB ratio prior to the All-Star break (1.23 ERA) before posting a 6.46 ERA in 23 2/3 second-half innings. While there’s certainly a correlation with the food poisoning, detractors can note that Janssen’s strikeouts and ground-ball rate were down significantly, even in the first half.
As shown in MLBTR’s Transaction Tracker, ACES has negotiated multiple contracts for free agent relievers over the past couple of offseasons, including Brandon League, Randy Choate, Santiago Casilla, Joaquin Benoit and Grant Balfour, and they also negotiated Jonathan Papelbon’s record contract with the Phillies.
