On Andrews, I have to disagree. He's had 59 career minor league outings, pitching 92.1 innings - or 1.5649 innings per outing on average. Let's round it up to one and two-thirds innings per outing. His 2018 (https://www.baseball-reference.com/register/player.fcgi?id=andrew003cla&type=pgl&year=2018) and 2019 (https://www.baseball-reference.com/register/player.fcgi?id=andrew003cla&type=pgl&year=2019) show that he went an inning or less in only 21 of the 59 games. By comparison, he's pitched at least two innings in 26 of those 59 career outings. The other 12 were 1.1 or 1.2 innings. This points to him being developed as that "fireman" - similar to what Hader does at the MLB level. He comes in, goes an inning-plus, and gets the team to the closer. Now, let's look at Torres-Costa. His career numbers are 148 games in which he's pitched 221.2 innings. That is an average of 1.49 innings per appearance. Now, if you remove the 2019 season where he was back on the tail end after recovering from Tommy John surgery, it goes to 1.509 innings per appearance (217.1 IP in 144 games). Or, just enough to say we could round him UP to the same one and two-thirds innings that Andrews has. Taking the 2015 (https://www.baseball-reference.com/register/player.fcgi?id=torres000qui&type=pgl&year=2015), 2016 (https://www.baseball-reference.com/register/player.fcgi?id=torres000qui&type=pgl&year=2016), 2017 (https://www.baseball-reference.com/register/player.fcgi?id=torres000qui&type=pgl&year=2017), and 2018 (https://www.baseball-reference.com/register/player.fcgi?id=torres000qui&type=pgl&year=2018) logs into account, we see Costa has done more of the LOOGY/one-inning appearances, but in 2017, he had seven appearances of more than three innings - and went as many as four and a third innings (13 outs) in a single appearance. He's still been more likely to go over two innings in an outing as opposed to less than an inning. But again, looking at the pattern of usage over the full minor-league seasons... Torres-Costa also appears to have been used in multi-inning relief, often to shut down an opposing team. Again, you could say it's the same sort of role Hader's in at present. The Tommy John may make him more of a Claudio replacement. The game logs and the numbers tell me that their performance will be a factor in Hader's availability. If they are both performing at their 2018 levels... that will have an effect. The same will be applicable if they both have Zack Brown flameouts and get lit up. The former scenario makes Hader more available. The latter scenario will make him less available.
