What Does SU Mean in Baseball?

Imagine being the last line of defense, the one tasked with ensuring the team’s victory. It’s intense, right? That’s exactly what an SU or Set Up Pitcher in baseball is all about.

In the baseball lexicon, “SU” stands for “Set Up Pitcher” or “Set Up Man”. This role is held by a relief pitcher, who takes the mound just before the Closer, typically in the tense moments of the eighth inning.

The Set Up Pitchers are often considered the second-best relief pitchers on the team. They are accountable for keeping the game in check, laying the groundwork for the Closer, and, ultimately, setting the stage for victory.

Mostly, they’re expected to pitch just one inning, but that one inning can make or break the game. Intrigued? Let’s dive deeper into the fascinating role of an SU in baseball.

What is SU in Baseball, and How is it Used?

As you delve into the fascinating world of baseball statistics, you may come across some abbreviations that could stump you.

“SU” is one such term that often leaves even avid baseball fans scratching their heads. So, what’s the deal with this mysterious “SU” acronym?

Breaking Down SU

In baseball, “SU” stands for “Straight Up.” It’s a term borrowed from the betting terminology and is predominantly used in the context of baseball wagering.

An SU result refers to whether a team won or lost without considering the point spread.

How is SU used in Baseball?

Now that we’ve cracked the code, consider how “SU” is practically used. In baseball betting, you might say a team is “10-5 SU in their last 15 games.”

This means the team has won 10 games and lost 5, regardless of the odds or the run difference in each game.

In Context of Baseball Stats

While “SU” primarily finds its place in betting, it can also be useful for analyzing a team’s performance.

In this context, a team’s SU record can give a raw look at their winning percentage, unadulterated by factors like run differential or home-field advantage.

Exploring the Role of the SU Pitcher

When you catch wind of an ‘SU’ in a baseball discussion, it’s not some cryptic baseball lingo. In the great game of baseball, SU stands for ‘Set-Up’. Primarily, it’s a role attributed to a pitcher, but a specific kind of pitcher, mind you.

Let’s unbox this baseball jargon and give you a clearer picture.

The Set-Up (SU) Pitcher Defined

As the name suggests, a Set-Up pitcher, or SU pitcher, is a type of relief pitcher in baseball. Their unique role? They are the ones who ‘set up’ the closing pitcher. It sounds pretty straightforward, but there’s a subtler art to it.

Stepping Up to Set-Up

Typically, an SU pitcher steps onto the mound in the late innings of the game, usually the seventh or eighth. This is when the game is tense, the stakes are high, and the closing pitcher prepares to swoop in.

Responsibilities of an SU Pitcher

  1. The SU pitcher must maintain or improve the team’s position in the game.
  2. They aim to keep the opposing team’s score in check to give their team a fighting chance.
  3. Most importantly, they set the stage for the closing pitcher to finish the game on a high note.

Notable SU Pitchers

Every team has its unsung heroes; in baseball, the SU pitchers often fit this bill. Some notable SU pitchers include Arthur Rhodes of the Cincinnati Reds and Mike Adams of the Texas Rangers.

The Difference Between SU and Closer in Baseball

Regarding baseball, the term ‘SU’ might have you scratching your head. Never fear, dear reader; we’re here to clear up the confusion and lay it all out on your home plate.

In baseball parlance, SU stands for ‘Set Up’. It’s a role typically performed by a relief pitcher who operates in the seventh or eighth inning, with the primary goal of setting the stage for the closer.

But you may wonder, how does this differ from a closer? Good question! 

How Does a Set-Up Man Differ From a Closer?

A set-up man and a closer may work similarly, but they play distinctly different roles during a baseball game. As the name suggests, the setup guy’s job is to ‘set up’ the game for the closer.

The SU’s primary function is to hold the lead or keep the game close in the final or penultimate inning before the closer comes in to finish the game.

On the other hand, the closer is typically the team’s best relief pitcher. He usually pitches in the ninth inning, intending to close out and secure the win.

Why is the Set-Up Role Important?

In the grand scheme of a baseball game, the set-up role is incredibly significant. The SU provides a bridge between the starting pitcher and the closer.

If the SU does his job well and keeps the opposing team at bay, it creates a smoother transition for the closer to come in and seal the victory.

So, while they might not get the same level of limelight as the closers, set-up men are unsung heroes in their own right.

So there you have it. The next time you hear ‘SU’ in a baseball context, you’ll know exactly what it means and its crucial role in the game. Stay tuned for more baseball lingo breakdowns!
