Astudillo is going to be sent down to Rochester Saturday, per Dan Hayes https://twitter.com/DanHayesMLB/status/1137197691329503233 Per Hayes again, it sounds as though as reliever will be coming up. Rochester had a double-header Friday with essentially a bullpen game in the second game. Here's a look at the 40-man guys recently: Hildy: Earned a 6 pitch save Friday, given up at least one run in 5/8 outings at Rochester, 8.38 ERA Moya: Threw 32 pitches Friday, 8.44 ERA in 16 outings Romero: Threw 33 pitches Friday, 5.70 ERA in 13 outings Vasquez: Currently on the 7-day IL retroactive to June 4th, 6.14 ERA in 8 outings Littel: Threw 37 pitches Friday, 3.97 ERA in 10 outings Stewart: Threw 95 pitches Friday, 4.11 ERA in 10 outings Thorpe: Last pitched Wednesday, 5.95 ERA in 11 outings Smeltzer: Sent down Friday and therefore ineligible to come back up Gonsalves: On IL, only pitched 2 innings this year For the life of me I don't see any reliever worthy of returning/coming to the major league club, if i had to make my best guess it would be Littel due to a shortened "primary" outing Friday but he showed himself largely ineffective in relief earlier this season. Hayes doesn't make a report of Astudillo being DFA'd so the reliever coming up would have to be from this bunch. It's possible an arm is called up just to eat some innings for a day and then return to Rochester after Saturday or Sunday, that would seem like the most likely scenario.
