contract and was released on August 7. Acereros de Monclova On February 21, 2017, Janssen signed with the Acereros de Monclova of the Mexican League. Janssen posted an 0-3 record and 4.30 ERA in 15 appearances for Monclova before he was released on May 16, 2017. Pitching style Janssen relies mostly on a four-seam fastball in the 91–93 mph range, and a cutter at 90–91. He also features a sweeping curveball (76–78), a two-seam fastball (low 90s), and a slider (mid-80s). The slider is almost exclusively used against right-handed hitters, with the two-seamer being its replacement against left-handers. Janssen's curveball has become an excellent "out pitch"; in 2012, batters hit .128 against it, and its whiff rate was 39%. Janssen has become an excellent control pitcher, walking only 1.6 batters per 9 innings in 2012. He has emphasized a low walk rate in becoming a successful pitcher: "I pride myself, as much as I can, in not walking hitters. ... I can live with giving up hits—they're going to happen—but walks are tougher to swallow."
