Glasnow looking totally dominant in relief - upper nineties on the edges of the zone with a fall off the table curveball. We have to see a good amount of repetition, but I've kept as close an eye on him as anyone this spring, and outside of the one start, basically all of the appearances have been like this. Last spring, he was like this a fair amount of the time, but he would also get himself into some dicey situations. He just looks a lot more in control, particularly with the way he uses the fastball to set things up. The command isn't precision perfect, but he's seemed to lock-in on the kind of ranges and zones where he can set up the other stuff, and then in particular what is helping is that the curveball is devastating most of the time, as opposed to maybe 10-20% of the time.
Edit: probably spoke a bit too soon, as Glasnow runs into a bit of trouble in his third inning. Just caught too much of the heart of the plate a few times, but didn't get tagged for too much damage. This is the kind of experience that may prove difficult to get outside of mop up duty, since in a closer game, you might guess the long relief goes more like 2 innings. Still, there's plenty to work with as we start the season, but it'll be interesting to see what kinds of actual situations they use him and Brault in.
Glasnow stays on for a fourth inning in the seventh and commands a strikeout, a one-pitch weakly hit groundout, and gives up a single. Overall nice to see - 6 Ks, mostly weak contact, mostly commanding the zone and being in control vs batters. Again, the really interesting thing will really be when he's pitching in a game with a one or two run lead, where there isn't much room for one or two mistakes. Searage was interviewed during this game and make the remark that Brault and Glasnow could still get situational work if long relief opportunities aren't really opening up, so really we'll just have to see. It does seem like they can get a lot of work for 2ish innings at a time while having certain starters avoid the times through the order penalty.
Edit #2: Looks like the Pirates are not going with Brentz:
Pirates put Bryce Brentz on waivers
This makes sense to me. Osuna has really been locked in, but with him having options, and all the talk of taking an extra pitcher, I wonder if this could speak to a more aggressive bullpen strategy to start the season? I'd prefer to see Osuna getting at-bats and also reps at 3B in AAA, so that he's a bit more primed for a depth role higher up the chain next year or later in the summer if Freese is moved, but there's no denying that he's absolutely crushed a lot of baseballs this spring. Still, I wonder if an extra bullpen arm would allow the team a bit of an avenue to use Glasnow/Brault a combined total of 3 times a week, to try and aggressively offset a times through the order penalty, but not totally tax the bullpen. In order for that to really work, I think you'd need to have them occasionally finish a game out entirely with four innings or something, which would mean that they are down for 4 days or so, during which Neversaukas or whoever would need to be able to chip in with some middle relief.
Keeping an extra arm could just be a flexibility move, but it's hard to see how it's necessary so early in the season.
