Of course he has a 73 wRC+, his f***ing BABIP is below the Mendoza line. Martin and Ryan Goins have the same career BABIP (.283), I think it says a lot that while running into the worst luck in the league he's still serviceable.
He has a .192 BABIP, he may not be Aaron Judge out there but his batting line should be a lot better, he's walking a ton and the power hasn't disappeared or anything.
Romano was awful dude, 4 walks and 3 strikeouts over 5 innings is not good at all. Minor league ERA is probably as irrelevant a stat as you could use to judge anyone.
Jack Morris was in his 4th MLB season posting consecutive 3.5 win campaigns at Romano's age.
Because we're playing in the f***ing National League and you're not letting the pitcher hit in the 8th inning, is that so hard to grasp? Blame it on the league and its archaic rules.
