Rangers release left-hander Michael Kirkman

Back in December the Rangers non-tendered Michael Kirkman and then re-signed him to a minor-league contract, but now they’re released the 28-year-old left-hander.

Kirkman has generally been an effective middle reliever, pitching parts of five seasons for the Rangers, but he spent most of last year in the minors and has struggled with shoulder problems all spring.

As a lefty with a mid-90s fastball and 103 strikeouts in 107 career innings he should be able to latch on somewhere else pretty quickly, but Kirkman’s health and poor control are holding him back.

MLB’s juiced baseball is juicing Triple-A home run totals too

There has been considerable evidence amassed over the past year or two that the baseball used by Major League Baseball has a lower aerodynamic profile, leading to less drag, which leads directly to more home runs. If you doubted that at all, get a load of what is happening in Triple-A right now.

The minors have always had different balls than the majors. The MLB ball is made in Costa Rica at a Rawlings facility. The minor league balls are made in China. They use slightly different materials and, by all accounts, the minor league balls do not have the same sort of action and do not travel as far as the big league balls. Before the season, as Baseball America reported, Major League Baseball requested that Triple-A baseball switch to using MLB balls. The reason: uniformity and, one presumes, more accurate analysis of performance at the top level of the minor leagues.

The result, as Baseball America reports today, is a massive uptick in homers in the early going to the Triple-A season:

Last April, Triple-A hitters homered once every 47 plate appearances. As the weather warmed up, so did the home run rate. Over the course of the entire 2018 season, Triple-A hitters homered every 43 plate appearances. So far this year, they are homering every 32 plate appearances. Triple-A hitters are hitting home runs at a rate of 135 percent of last year’s rate.

Again, that’s in the coldest, least-homer friendly month of the season. It’s gonna just get worse. Or better, I guess, if you’re all about the long ball.

Which you had better be, because if they did something to deaden the balls and reduce homers, we’d have the same historically-high strikeout and walk rates but with no homers to provide offense to compensate. At least unless or until hitters changed their approach to become slap hitters or something, but that could take a good while. And may still not be effective given the advances in defense since the last time slap hitting was an important part of the game.

In the meantime, enjoy the dingers, Triple-A fans.
