Off days seem to work pretty well for minor league updates. There’s not much going on with the big league team on these days, so we might as well look into the minor league system.
Today let’s start in Double-A. Austin Romine is always the other catcher in the Yankees system. He’s not considered one of baseball’s elite like Jesus Montero, and he’s not a raw mega-talent like Gary Sanchez, but Romine is a legitimate prospect his bat is heating up.
He hit a walkoff single on Tuesday, then he homered twice on Wednesday.  Romine got off to a slow start in the season’s first week, but in the past five games he’s collected nine hits including a double and two home runs. He has nine RBI in the his past five games after not driving in a run in any of his first six games. His slash line is up to .310/.420/.500.
Of course, in this system, Romine isn’t the only minor league catcher who’s been hitting lately.
Jesus Montero continues to rake for Scranton/Wilkes-Barre. He had another three-hit game last night, and although he hasn’t homered since April 9 and has yet to draw a walk, Montero is batting .423/.423/.558 through 11 games. Down in Charleston, Gary Sanchez is back from a brief stint on the disabled list and had a hit last night. While Sanchez was out — Josh Norris says it was a sore oblique, of course  — J.R. Murphy got some regular time behind the plate and his bat is still going strong with three homers, 13 RBI and a .326 average.
For the immediate future, the catching situation that has the most impact on the Yankees is happening in Tampa, where Francisco Cervelli is supposed to be begin a rehab assignment tonight.
• Kei Igawa is up from Double-A to start for Scranton/Wilkes-Barre tonight. Kevin Millwood is coming up from the Double-A roster to start for Scranton tomorrow. As Donnie Collins pointed out, Millwood should have time to make one start after tomorrow before his out kicks in. 
• Speaking of Triple-A starters, David Phelps and Adam Warren have turned in back-to-back gems this week. Phelps allowed three hits and struck out six through 6.1 innings on Tuesday night, then Warren followed with eight scoreless innings on Wednesday. Minor league pitchers — and big league pitchers for that matter — occasionally talk about creating a friendly rivalry in which one player’s success helps to spark another’s success. Those two outings could start something like that.
• Jorge Vazquez is up to seven home runs in Scranton, meanwhile Chris Dickerson has started hitting in Triple-A. Eight hits in his past four games has Dickerson’s slash line up to .292/.393/.375. He’s had two doubles and a triple in the past three days, his first extra-base hits of the year.
• Manny Banuelos is back from his blister and made his second start on Tuesday night. He allowed two hits and one unearned run through four innings for Double-A Trenton. Dellin Betances is still on the disabled list in Trenton, but he seems close to a return. 
• Good numbers from a name you might not know: Mikey O’Brien, a ninth-round pick in 2008, has a 2.16 ERA with 19 strikeouts through his first three starts with Charleston. He’s walked only three and his production has been pretty steady (his numbers aren’t the product of just one good start), but he has yet to get a win. O’Brien could be building on last season when he had a 2.08 ERA in Staten Island.
