5:40pm: Dennis Lin of the San Diego Union-Tribune tweets that Hessler will report to the Padres tomorrow and serve as the club’s 26th man for Wednesday’s double-header.
4:03pm: The Padres announced today that they have claimed left-hander Keith Hessler off waivers from the Diamondbacks. Arizona had designated Hessler for assignment back on April 30 in order to clear room on the roster for lefty Zac Curtis, whose contract was selected from Triple-A.
The 27-year-old Hessler has appeared in 20 games for the D-backs over the past two seasons but struggled, yielding 14 earned runs in 15 1/3 innings. He’s struggled in similarly limited exposure to the Triple-A level as well (5.32 ERA in 22 innings), but overall he enjoyed a strong season in the minors last year, working to a combined 2.14 ERA with 9.9 K/9 against 2.3 BB/9 across three levels. Lefties batted just .195/.246/.322 against Hessler between the Majors and Minors in 2015.
