Pittsburgh Pirates: Two Minor League Signings That Could Make an Impact in 2024

The Pittsburgh Pirates signed right-handed relievers Ben Heller and Ryder Ryan to minor league deals, but they could prove to be under-the-radar pick-ups.

Occasionally, a team will sign a player to a minor league contract and find a diamond in the rough. The Pittsburgh Pirates were able to do this last year with Ryan Borucki, signing him to a minor league contract, and ended up giving them an ERA of just 2.45, a walk rate a touch under 3%, and one of the best pitchers at limiting hard contact. The Pirates recently signed two more relievers to minor league deals this off-season.

But these two arms definitely have the potential to become under-the-radar deals, like Borucki. That’s not to say that either will become the next Mariano Rivera, but they both have enough upside to potentially become quality middle relievers. But who are they? What makes them potential under-the-radar moves?

Ben Heller

The Pirates signed Ben Heller during the Winter Meetings. The right-hander has mostly served as an up-and-down depth reliever since 2016, appearing in five of the eight total seasons since his 2016 debut. Last year, Heller pitched 18.2 innings for the Atlanta Braves, owing a 3.86 ERA but a poor 5.02 FIP, 1.45 WHIP, a walk rate of 13.4%, and a sub-20% strikeout rate.

But Heller pitched a lot better at Triple-A, both for the Braves and Minnesota Twins’ Triple-A affiliate. He pitched 44 innings between the two teams, working to a 3.27 ERA, 3.35 FIP, and 1.23 WHIP. He had a 28.9% strikeout rate, and despite Triple-A introducing the automated strike zone, Heller only had a 7.6% walk rate. On top of that, Heller had a 51.4% ground ball rate and HR/9 of 0.41.

But aside from decent Triple-A numbers, what other reasons are there to believe Heller could be the next Ryan Borucki? Heller’s sinker displayed well above average movement last season with 25.2 inches of vertical movement (13% better than average) and 17.5 inches of horizontal break (14% better than average). Opponents had a hard time facing his cutter with a .214 batting average and slugging percentage, meaning he didn’t give up a single extra-base hit with his cutter. But the real impressive offering here is his sweeper.

Heller’s sweeper was untouchable last year, and that’s not hyperbole. He threw it 13.3% of the time and did not allow a single hit. His 78.6% whiff rate was the highest in baseball last year among pitchers who threw sweepers. It’s not just the highest this year either; it’s the highest whiff rate Statcast has ever recorded on a sweeper, and it’s not even relatively close. The next closest, Jose Cuas, has the second-highest whiff rate on a sweeper in the Statcast era, and he sat at 64.3% last year, a gap of 14.3%.

What Heller should do next year is drop his changeup. Even though he only used it against 12 batters last year, and just 12.7% of the time, five of them got a base hit (he allowed 13 hits in total). Of those five hits, two were extra-base hits, including a home run and triple. It is a small sample size, but Heller’s change-up was the only pitch in his arsenal that didn’t register a positive run value.

Ryder Ryan

Ryder Ryan has the bare minimum major league experience under his belt. Last year, he pitched a single scoreless inning for the Seattle Mariners, facing four batters, striking out two, and walking one. He spent nearly all of his year at Triple-A Tacoma, where he posted a quality 3.76 ERA, 4.17 FIP, and 1.24 WHIP. He clocked in with a 9.6% walk rate, a 24.3% strikeout rate, and a strong 0.65 HR/9 through 55 innings.

Ryan has pitched extremely well in the last two seasons. The right-hander owns a 3.70 ERA, 4.55 FIP, and 1.31 WHIP over his last 114.1 innings pitched. Ryan has a 25.1% strikeout rate, albeit a less impressive 10.4% walk rate. But he’s been great at limiting home runs with a HR/9 of just 0.87. Ryan gets both strikeouts and ground balls, clocking in with a ground ball rate over 50% at 51.7%.

I know what you may be saying: how is a high-3’s ERA and mid-4’s FIP “pitching extremely well?” Well, it’s because he’s been pitching in the Pacific Coast League. The league average ERA last season in the PCL was 5.70, and the average ERA in 2022 was 5.39. An ERA of 5.00 makes you a good pitcher in the league. Last season, over 60% of the pitchers who had 50+ frames had an ERA of 6.00 or higher.

There have only been ten pitchers in the PCL to toss 80+ innings across the last two seasons with an ERA under 4.00. Ryan had the 6th lowest ERA. Ryan also ranks 13 out of 93 pitchers in FIP, 26th in K%, and 12th in WHIP. His ground ball rate is also the 9th best and is one of 23 pitchers with a HR/9 under 1.00 (min. 80 innings pitched). He ranks 14th over the last two years in this stat. Last season, among pitchers with 50+ frames, he ranked in the top ten in ERA, FIP, WHIP, and xFIP. He was also one of just 29 pitchers with a walk rate under 10% (league average was 12.3%).

The fact that Ryan has now posted a sub-4.00 ERA in back-to-back seasons in the PCL is a feat in and of itself and deserves some recognition. Not to mention, he’s been above average to well above average in most other numbers as well. Trying to pitch well in the PCL is like trying to walk a minefield with a blindfold and ear muffs on. It got a lot harder for pitchers last year with the implementation of reviewable ball-strike calls. If you ask me, if you’re able to pitch well in the PCL over an extended period, like Ryan has, then you must be doing something right.
