Yes, they have changed, but can we say it's for the better? From a baseball "union" stand point yes, there are more pitching "jobs" now than ever. Back in the day, there was 4-5 starters, a couple of set ups and a closer. The rest was mop up guys. Today, the starters rarely even get 200 innings, and bullpen guys are used more than ever. Some rosters are half pitchers.Things have changed a bit from when Tom Browning was a rookie. I'm sure there's reasoning why they don't "push" guys. Also, Michael Lorenzen does a ton of work on flexibility and core strength. but hasn't thrown more than 83.1 innings in a year except for the year he started.
