29-year-old Jim Henderson, called up by the Brewers earlier in the day, made his major league debut Thursday night, retiring all three Nationals he faced in his inning of work.
Henderson was a 10-year minor league veteran, having been picked by Expos in the 26th round of the 2003 draft. After he failed as a starter in low-A ball in 2005, the Nationals shifted him to the bullpen, where he’s been ever since. His results have largely been mixed in stints in three different farm systems, but he broke through in Triple-A this year, amassing a 1.69 ERA and 15 saves as Nashville’s closer.
While Henderson had a 5.46 ERA in Double-A in 2010 and a 4.28 mark between Double- and Triple-A last year, his mid-90s fastball has kept him employed. He probably doesn’t have enough to go with it to contribute as more than a middle reliever, but it’d be a nice story if he happened to surprise.
A day after throwing an immaculate inning — getting through an inning on three consecutive strikeouts with nine pitches — against the Mariners, Dodgers reliever Zac Rosscup was placed on the 10-day disabled list with a left calf strain. The move made room on the 25-man roster for Kenley Jansen, who is back after missing some time due to an irregular heartbeat.
Rosscup pitched the ninth inning of Sunday’s 12-1 win over the Mariners. He struck out Kyle Seager, Ryon Healy, and Cameron Maybin on three pitches each. Rosscup is the fourth pitcher to throw an immaculate inning this season, joining Kevin Gausman, Max Scherzer, and German Marquez. 2018’s four immaculate innings is still far behind 2017’s record of eight.
Rosscup has pitched only 6 2/3 innings in the majors this year. He has yielded five runs (all earned) on seven hits and a walk with 10 strikeouts. He missed a significant amount of time earlier this season due to a blister on his left middle finger.
