Another pitching staff shuffle

Another series of roster moves Wednesday for the Twins, none of which involved Randy Rosario:

• Right-handed pitcher Nick Tepesch, who had been on the Triple A disabled list but occupied a spot on the 40-man roster, was released.
• Left-handed pitcher Hector Santiago was placed on the 10-day disabled list and was to return to the Twin Cities to have his throwing shoulder examined. This opened a spot on the 25-man roster.
• Right-handed pitcher Chris Heston was claimed on waivers from the Los Angeles Dodgers. He inherits Tepesch's spot on the 40 and Santiago's spot on the 25 (and presumably Santiago's rotation berth, although I don't know how stretched out he is).

Heston never actually pitched for the Dodgers; they claimed him on waivers from Seattle on May 26 and almost immediately tried to get him through waivers themselves. He did make one three-inning appearance for their Triple A club.

All I really know about Heston is that he spent the 2015 season in the San Francisco rotation, making 31 starts and throwing 177-plus innings with a 12-11 record and 4.15 ERA but also including a no-hitter (June 9 against the Mets in New York). He's 29 and has six major league appearances total the past two seasons.

I'm not counting on much from him. Remember, the Dodgers just picked up Jason Wheeler from the Twins; presumably the Dodgers prefer Wheeler to Heston, and the Twins just jettisoned Wheeler. We are, again, dealing with marginal pitchers.
